Surface Geophysical Methods

Surface Geophysical Methods (Astm D 6429)

Surface geophysics allow subsurface features to be located, mapped, and characterized remotely by making measurements at the surface without drilling and recognizes the differences in physical properties of various materials. Geophysical methods can identify where changes in the subsurface occur and these changes are often associated with geological, man-made or environmental features of interest. Surface Geophysics provides a rapid, cost-effective, non-invasive approach for solving a variety of environmental, geotechnical, groundwater and archaeological-related issues. There are many surface geophysical methods available to investigate and solve subsurface problems. Among the applications of geophysics that ACES has performed are:

Electrical Resistivity MethodElectrical resistivity methods involve the measurement of the apparent resistivity of soils and rock as a function of depth or position. The resistivity of soils is a complicated function of porosity, permeability, ionic content of the pore fluids, and clay mineralization. The most common electrical methods used in hydrogeologic and environmentalinvestigations are vertical electrical soundings (resistivity soundings), resistivity profiling and electrical resistivity tomography.

During resistivity surveys, current is injected into the earth through a pair of current electrodes, and the potential difference is measured between a pair of potential electrodes. The current and potential electrodes are generally arranged in a linear array. Common arrays include the dipole-dipole array, pole-pole array, Schlumberger array, and the Wenner array. The apparent resistivity is the bulk average resistivity of all soils and rock influencing the flow of current. It is calculated by dividing the measured potential difference by the input current, and multiplying by a geometric factor (specific to the array being used and electrode spacing).

Vertical Electrical Sounding (VES)

In resistivity soundings, the distance between the current electrodes or the distance between the current and potential dipoles is expanded in a regular manner between readings, thus yielding information of the electrical properties of soils from deeper and deeper depths. Models of the variation of resistivity with depth can be obtained using model curves or forward and inverse modeling computer programs.

Main applications, to :

• Characterize subsurface hydrogeology• Determine depth to bedrock/overburden thickness• Determine depth to groundwater• Map stratigraphy & Map clay aquitards • Map salt-water intrusion • Map vertical extent of certain types of soil and groundwater contamination • Earthing and corrosion control design

Electrical Resistivity Profiling (ERP)

In resistivity profiling, the electrode spacing is fixed, and measurements are taken at successive intervals along a profile. Data are generally presented as profiles or contour maps and interpreted qualitatively.

Main applications, to :

• Map faults• Map lateral extent of conductive contaminant plumes • Locate voids • Map heavy metals soil contamination • Delineate disposal areas • Map paleochannels • Explore for sand and gravel & Map archaeological sites

Surface Geophysical Methods

2D & 3D Electrical Resistivity Tomography (ERT)

The technique utilizes pairs of current and potential electrodes inserted into the ground. By measuring the voltage between the potential electrodes the apparent resistivity of the subsurface can be determined. By taking a large number of resistivity readings using different geometrical arrays a 2-dimensional profile of the subsurface can be generated. The electrodes are connected by a multicore cable to a field computer. Data are processed in the field as an initial quality control check. The data is inverted using the Res2dinv/Res3dinv or Earth Imager (2d&3d) imaging software to produce an apparent resistivity depth model. Material types and properties can then be assigned based on the geophysical data in conjunction with available geological data.

Main applications, to:

• Determine the depth and thickness of geologic strata• Detect lateral changes and locate anomalous geologic conditions• Measure soil resistivity for estimating metal corrosion rates and designing grounding grids• Map saltwater intrusion and contaminant plumes• Locate buried wastes (e.g. locate landfill boundaries)• Azimuthal measurements to determine fracture orientation• Create a detailed 3D resistivity model • Monitor changes in groundwater or contaminants

Spontaneous potential or Self Potential (SP)

The self-potential (SP) survey method is a passive geophysical technique that measures extremely small, naturally occurring voltage variations in the earth. The technique is based on the observation that when certain materials are in contact with either a different material (e.g., buried iron next to buried copper) or a localized change in the condition of the same material (e.g., interface of saturated and unsaturated condition), an electrical current is created. This current is readily detectable with inexpensive, portable voltage measuring instrumentation.

Main applications, to:

• Detection of leaks in dams and dikes• Hydrogeology and geothermal power, where one is interested in the flow of water in the ground• Locating base metals • Delineating spring catchments areas • Detecting and delineating sinkholes Mapping zones vulnerable to pollution • Locating leaks in dams and leachate leaks around landfills

Induced Polarization (IP)

This is an active method that is commonly done in conjunction with DC Resistivity.It employs measurements of the transient (short-term) variations in potential as the current is initially applied or removed from the ground.

Main applications, to:

Mineral Exploration Oil shale investigation Map clay and sit layers which serve as confining units separating unconsolidated sediment aquifers Distinguish geologic layers which do not respond well to an electrical resistivity survey Resolving thin stratigraphy layers while modelling electrical resistivity data can be reduced by analysis of IP data

Surface Seismic Method

Seismic methods involve the measurement of elastic waves traveling through the subsurface. Stratigraphy, structure, and material properties can be assessed with seismic methods. Three of the most useful seismic methods for shallow applications include refraction, reflection, and multi-channel analysis of surface waves (MASW).

Seismic Refraction (SR) ‒ ASTM D 5777

Seismic Refraction is a method to determine the P-wave velocity structure of the subsurface and the depths to layers with a significant change in P-wave velocity (e.g. sediment to rock). The P-wave velocity Vp is dependent upon the bulk modulus, the shear modulus and the density (ASTM D5777). Seismic P-waves are generated on the surface by an energy source such as a simple sledge hammer. The P-waves propagate through the soil and rock, and when the seismic waves encounter interfaces between materials of different seismic velocities, the waves are refracted according to Snell’s Law. The seismic wave will travel along the interface with a velocity of the underlying (faster) layer. An array of geophones is placed along the survey line and a seismograph is used to record the travel-times of the seismic signals.

Main applications, to:

• Map bedrock topography• Map faults in bedrock• Estimate depth to groundwater• Estimate bedrock rippability• Evaluate rock properties• Mapping geologic strata and anomalous conditions

Seismic Reflection ‒ ASTM D 7128

The Seismic Reflection technique measures the two-way travel time of seismic waves from the ground surface downward to a geologic contact where part of the seismic energy is reflected back to geophones at the surface (ASTM 7128-05). Reflections occur when there is a contrast in the density and velocity between two layers. The reflection method provides a high resolution cross section of soil/rock strata along a profile line. For geotechnical and environmental work, reflection measurements are typically made from about 50 to 1,000 feet deep on land. More detailed (higher-frequency) and shallower data can be obtained on water

Main applications, to:

• Map subsurface stratigraphy • Map lateral continuity of geologic layers• Map buried paleochannels • Map faults in sedimentary layers• Map basement topography • Mapping structural and anomalous geologic conditions.• identify smaller targets such as mines, tunnels, and caves

Seismic Refraction Tomography (SRT)

Seismic refraction tomography uses the same equipment as for standard refraction work, but using a different field procedure and data processing.

Main applications, to:

• Bedrock profiling and location of faults and fracture zones• Determine the thickness of the various overburden layers • Determine the depth to the water table• Identify sub-vertical geological contacts • Discontinuous low velocity zones • Fracture zone orientation • Fault orientation and thickness

Surface Geophysical Methods

Surface Geophysical Methods

Multi Channel Analysis of Surface Waves (MASW)

MASW is a geophysical method that uses the dispersive characteristics of surface waves to determine the variation of shear wave (S-wave) velocity with depth. MASW is a non-intrusive method that is performed on the ground surface.

Main applications, to:

• UBC/IBC site classification for seismic design • Earthquake site response • Liquefaction analysis Soil Compaction control Determining the depth and thickness of Stratigraphy layers• Identifying low-velocity (weak) zones such as voids and sinkholes• Determining soil and rock elastic properties

Spectral Analysis of Surface Waves (SASW)

A relatively new in-situ seismic method for determining shear wave velocity profiles, the SASW method measures the dispersive characteristic of Rayleigh waves when traveling through a layered medium.

Main applications, to:

• Soil compaction control • Pavement evaluation• Mapping subsurface Stratigraphy• Alternative techniques for borehole seismic techniques• Profile Shear Stiffness vs. Depth• Predict Ground Deformation Under Loading• Assess Integrity of Concrete Structures• Assess Liquefaction Potential• Determine Earthquake Site Response

Other Methods

Ground Penetrating Radar (GPR)

Ground penetrating radar (GPR) is a surface method that uses the proper-ties of electromagnetic waves to create a detailed image of subsurface layers. Ground penetrating radar, like other radar techniques, utilizes an electro-magnetic (radio wave or microwave) pulse. The electromagnetic pulse is of a lower frequency (80-500 MHz) than other radars, to obtain better penetration in the earth materials. Ground penetrating radar (GPR) sends out an electromagnetic pulse which is reflected from a "target" and returns toward the ground surface which is detected by the GPR antenna. This reflection is detected and shows the location and shape of the subsur-face objects and features. The antenna is pulled slowly along the ground surface to produce a continuous subsurface profile

The GPR method can be used for very rapid, high resolution mapping of the shallow subsurface to: • Locate metallic and nonmetallic pipes and utility cables.• Delineate underground storage tanks (metallic and nonmetallic).• Map rebar in concrete structure.• Map landfill boundaries.• Delineate pits and trenches containing metallic and nonmetallic debris.• Delineate leach fields and industrial cribs.• Delineate previously excavated and backfilled areas.• Map shallow groundwater tables.• Map shallow soil Stratigraphy. • Map shallow bedrock topography.• Map subsurface voids and cavities. • Characterize archaeological site.

Surface Geophysical Methods

Surface Geophysical Methods

Micro Gravity ( MG )

The gravity method involves measurement of the gravitational attraction exerted by the earth at a measurement station on the surface. The strength of the gravitational field is directly proportional to the mass and, therefore, the density of subsurface materials. Anomalies in the earth’s gravitational field result from lateral variations in the density of subsurface materials. The intensity of the force of gravity due to a buried mass difference is superimposed on the larger force of gravity due to the total mass of the earth. Thus two components of gravity forces are measured at the earth's surface, a general and relatively uniform component, and a second component of much smaller size which varies due to lateral density changes.

The gravity method can be used to:

• Detect natural or manmade voids.• Variations in the depth of bedrock.• Geologic structures of engineering interest. Investigate the Poleo Channel Systems.

Magnetic methods

The magnetic method involves the measurement of the intensity of the earth's total magnetic field, a component of the earth's magnetic field, or the horizontal or vertical gradient of the earth's magnetic field. Anomalies in the earth's magnetic field are caused by induced or remnant magnetism. Induced magnetic anomalies are the result of secondary magnetization induced in a ferrous body by the earth's magnetic field. The shape and amplitude of an induced magnetic anomaly is a function of the orientation, geometry, size, depth, and magnetic susceptibility of the body as well as the intensity and inclination of the earth's magnetic field in the survey area. The magnetic method is an effective way to search for small metallic objects, such as buried ordnance and drums, because magnetic anomalies have spatial dimensions much larger than those of the objects themselves

The magnetic method can be used to:

• Locate abandoned steel well casings • Locate buried tanks and pipes • Locate pits and trenches containing buried metallic debris • Detect buried ordnance • Map old waste sites and landfill boundaries • Clear drilling locations • Map basement faults and geology Investigate archaeological sites and delineate paleochannels

Surface Geophysical Methods

Borehole Geophysics

Borehole GeophysicsBorehole geophysics utilizes boreholes or wells to make geophysical measurements. Compared to geophysical measurements made on the ground surface, they have better resolution in the depth dimen-sion. Borehole geophysics can be performed in a single borehole as in the borehole logging, or in two or more boreholes for cross-hole resistivity, and seismic measurements, etc. Single borehole test can provide detailed information in the immediate area of the borehole, while cross-hole measurements and sometimes with additional ground surface sensors can provide more information in a much broader area, especially between or among the boreholes.

Borehole Seismic Surveys

Borehole seismic surveys are carried out to measure compressional (P) and shear (S) wave velocities of soils or rock surrounding a borehole or between boreholes. The method is carried out either downhole or crosshole depending on the location of the geophone sensors and seismic source. Borehole P and S wave velocity results can be used to determine elastic moduli of soil and rock for earthquake assessment of site response and liquefaction potential, evaluate foundation conditions for machine vibratory loads, determine material damping characteristics, define geological boundaries, locate voids or anomalies in geological layering using tomography mapping, analyze embankment stability, and assist in determination of design parameters for structures.

ACES provides a wide range of borehole seismic logging depending on the depth of investigation and site conditions. These include:

Standard Cross Hole Seismic Test (ASTM D 4428/4428M)

Cross hole seismic surveys requires two or three cased/ grouted boreholes at straight line with spacing (3-6)m. In this method, the one-way travel time of seismic energy transmitted between boreholes is measured to determine the bulk material properties of the intervening materials. An external seismic energy source is used within one borehole, and arrays of tri-axial geophone receiving geophones are lowered into near-by boreholes. The one-way seismic wave travel times are based on the initial arrival of energy at each geophone. Knowing the separations of each borehole and the depths of the external seismic source and each receiver, the compressional and shear seismic velocities may be calculated for each depth interval.

Down Hole Seismic Test (ASTM D 7400)

Down hole seismic requires one cased/ grouted borehole. In this technique an external seismic source such as a hammer striking a plate, is applied at a fixed distance from the borehole to generate P-wave and Shear wave energy by striking the ends of a large wooden block that is held in place by a vehicle or heavy weight. By striking both ends of the wooden block, both positive and negative shear waves are generated, which enables the seismic interpreter to distinguish the shear wave arrivals from compressional wave and extraneous signal noise. The waves are recorded by tri-axial geophone that is coupled to the borehole wall at various depths within the borehole.

Borehole Geophysics

Boreho le Geophysics

Full Wave Form Sonic Logging

The method requires one borehole filled with water for each test location. During logging, a series of high frequency sonic impulses are emitted by the tool. Following their passage through the borehole fluid and formations, these impulses are detected by receivers at various distances from the transmitter.

PS Suspension Log

The Suspension P-S Logging System is a new technique for measuring P and S-wave velocities in deep boreholes. The characteristic feature of this technique is that the downhole sonde contains both the electromagnetic vibration wave source and two receiver units separated by flexible tubing. The sonde suspended in a fluid-filled borehole, generates and records high quality shear and compression wave velocities at specified depths without having to clamp the probes to the borehole wall.The system, as presently developed, can be applied to depths of 500 meters (1600 feet) and has been used at various site locations with different geological conditions. The system has been used on land, and off-shore projects.

Seismic Cone Penetration Testing (SCPT)

This method is used for measurement of shear wave velocity and other common parameters such as cone resistance, sleeve friction & pore water pressure by using seismic piezocone. This technique is a reliable, cost effective technique to determine in situ seismic wave velocities in soft materials conditions in the upper 100-200 ft of subsurface.

Seismic Tomography Surveys

Seismic tomography is applied to situations where detailed pictures of the subsurface are needed. Tomography utilizes both borehole to surface and borehole to borehole shooting. Sophisticated computer programs invert the field data into a tomographic image showing a very accurate two dimensional diagram of the velocity structure in the surveyed areas. Tomography is employed to detect or map:

• Discontinuous low velocity zones • Fracture zone orientation • Fault orientation and thickness • Dynamic rock moduli and quality • Grout curtains

ACES provides the following services: Cross Hole Seismic Tomography

Borehole seismic tomography involves the measurement of the travel times of seismic ray paths between two or more boreholes in order to derive an image of seismic velocity in the intervening ground. Data is collected using one hole for the seismic source (normally sparkers) and measuring first-arrival times using strings of hydrophones in the others. Travel times are collected at regular intervals (usually 1- 2m) all the way down the hole(s) for each shot position. This results in a network of overlapping ray paths that can then be used to model the velocity profile.

Borehole Geophysics

P-Wave Tomography

Borehole Geophysics

Single Hole Seismic Tomography

The method requires one borehole per test location. The borehole is PVC-cased and grouted to ensure the hole remains open and that the casing is in firm contact with the soil or rock mass. Borehole Single hole tomography involves the measurement of the travel times of seismic ray paths between the borehole and surface in order to derive an image of seismic velocity in the intervening ground.

Parallel Seismic Test (P.S.T)

The Parallel Seismic (PST) method is a borehole test method for determining depth of foundation. The method can also detect major anomalies within a foundation as well as provide the surrounding soil velocity profile. The technique requires a borehole to be drilled parallel, and close to the target pile for installation of hydrophones, furthermore some portion of the structure must be exposed for hammer impact.

Geophysical Well Logging

In the borehole logging, geophysical sensors or probes are lowered down the borehole to collect data about the rock and soil properties adjacent to well, that are generally presented graphically along the depth dimension. There are many geophysical methods available to investigate and solve subsurface problems.

ACES provides the following well/Borehole logging services:

Used to identify temperature changes due to water-bearing zones or non-static water conditions. Temperature changes are normally related to water bearing zones in a borehole.

Similar to the resistivity tool. This tool is not deep sensing, and usually related to the borehole �uids. Frequently �uid conductivities are measured using electromagnetic methods and converted to �uid resistivity. Fluid resistivity is frequently used to evaluate groundwater quality.

The caliper log is used to measure the overall diameter of the borehole to identify washed-out zones, fractures, caving, borehole collapse or obstructions cement volume calculation for grouting. This tool can be used to develop an idea of borehole rugosity and may be useful in identifying the quality of the casing/rock interface.

Water �ow rate and direction along the borehole.

Bulk material density surrounding the borehole.This stratigraphic identi�cation tool is primarily used to di�erentiate between sands and clays in an unconsolidated environment or sandstone and shale in a consolidate.

This measures the electrical properties of the borehole and rock pore �uids present in and around the borehole. This tool is useful in identifying water-bearing zones, stratigraphic changes, and fractures. This measurement is performed using a referenc-ing electrode at the ground surface resulting in a bulk resistance measurement between the surface electrode and the in-well measuring tool.

This measures the electrical properties around the borehole. This tool is useful in identify-ing stratigraphic changes. This tool is di�ers from the single point resistance tool as it uses multiple electrodes spaced typically at 8, 16, 32 or 64-inches apart. Longer electrode spacing "looks" further into the formation into areas that may not have been in�uenced by drilling activities.When used in conjunction with the resistance log, this tool is used to determine stratigra-phy. This tool is normally used to infer rock grain size, permeability, and �owing (moving) groundwater.Measuring the deviation of a borehole is performed using a sonde with three axis magnetom-eters and accelerometers. Knowing borehole deviation is a requirement to correct for interpreted bedrock strike and dip in televiewer logs. Abrupt borehole deviations can pose problems for long pump settings in water supply wells.
