INTRODUCTION PT. Intilog Indonesia, an Indonesian company commenced operations in July 2007. Intilog has been established to provide specialist contract geophysical and geotechnical logging services and geophysical equipment sales and service in Indonesia and the South East Asian region. Intilog’s expertise is drawn from a team of key personnel with a combined total of twenty five years experience in the region and a close association with Robertson Geologging Ltd, probably the largest global supplier of slim-hole borehole-logging equipment in the world. There are thirteen geophysical logging systems in total and all reflect state of the art technology. A fully equipped workshop, technicians and a comprehensive inventory of spares ensures downtime is minimal in the event of a breakdown.

Intilog will endeavour to meet special client needs in the event equipment requested is not in the current inventory. A comprehensive operational and radiation safety management plan has been developed and approved by the Nuclear Energy Regulatory Agency (BAPETEN). Our key personnel are holders of radiation protection licences (Petugas Proteksi Radiasi) and new employees are given thorough training on the safe operation of equipment with special emphasis on the handling of radioactive material. Our aim is to achieve an incident free workplace and conduct our business with no adverse effects for personnel, property and the environment.

GEOPHYSICAL LOGGING EQUIPMENT LIST

SURFACE UNIT AND SOFTWARE

MICROLOGGER Based on modern dsp technology, the Micrologger2 is probably the most powerful portable logging system on the market. Lightweight and smaller in size than the average notebook, the Micrologger2 supports all RG probes including the latest acoustic and imaging types. WINLOGGER SOFTWARE RG Winlogger is the operating software for the Micrologger2 surface system. The product of years of development, RG Winlogger provides data acquisition, processing and reporting for the standard RG probe range.

WINCHES

500M WINCH A robust ‘no-frills’ unit, the 500m winch can be operated from a vehicle battery and is ideal for heavier probes in shallow boreholes.

MINI WINCH The RG Mini winch is portable, compact and robust. Its basic ‘no-frills’ design is aimed at long-term reliability under arduous conditions.

PROBES

SIDEWALL DENSITY PROBE The sidewall density gamma probe uses dual shielded detectors to provide a borehole- compensated density measurement with good bed-boundary resolution.

6

DENSITY GAMMA INCLINATION The Trisonde offers a convenient alternative to the standard RG sidewall density probe whenever borehole diameter is restricted and qualitative density measurements are acceptable. One common application is in logging through drill pipe when unstable borehole conditions prevent use of unprotected nuclear probes.

FOCUSED ELECTRIC The focussed resistivity (LL3) measurement provides excellent vertical resolution and a reasonable depth of investigation. SONIC SLIMHOLE This highly compact slimhole tool is designed specifically for geotechnical and mining applications. The probe acquires transit-time and full-waveform data simultaneously from a single transmitter and three receivers.

VERTICALITY The RG verticality probe provides accurate, continuous measurements of borehole inclination and direction.

ACOUSTIC TELEVIEWER The HRAT (High Resolution Acoustic Televiewer) provides a continuous high-resolution oriented ultrasound image of the borehole wall.

HI-RESOLUTION OPTICAL TELEVIEWER The Hi-OPTV provides a continuous very high resolution oriented image of the borehole walls using a conventional light source. A unique optical system based on a fisheye lens allows the probe to survey 360 degrees simultaneously.

Winch and probe combinations will be tailored to suit client requirements and application.
