(i) Figure A1.1 illustrates the datasets used by well-location, and Tables A1.1–1.2 lists the data

availability. Table A1.1 also provides the well names for well abbreviations, the latter used in

structure and isopach maps enclosed in this thesis.

(ii) Figure A1.2 provides a palynology zonations chart for the Gippsland Basin: the chart is used

to relate the palynology to the stratigraphy (Chapter 2

PREFACE—APPENDICES 1–3 _________________________

Appendix-1 figures, tables and text support the geological context in this thesis, as follows:

).

(iii) Section A1.2 details the methodology used for interpreting age-depth plots (Figures A1.3–

1.33): the latter provide additional hiatus markers that tie to the seismic data (Chapter 3).

(iv) The NEW hiatus-markers interpreted from the age-depth plots are listed in Tables A1.3–1.16

(Chapter 3); thus, adding to markers and tops that are publicly available.

(v) Tables A1.17–1.95 list publicly available formation tops and hiatus markers interpreted in this

study for individual wells. The depths and TWTs provide well-tie information for cross-sections

and seismic sections enclosed in this thesis, as well as providing a ready-made database for

future studies.

(vi) Table A1.96 lists the top of volcanic horizons intersected in wells. Volcanic horizons help

identify the top of the Golden Beach Subgroup and provide input into the understanding of

tectonovolcanic evolution (Chapter 3) and sealing across-fault (Chapter 6).

Appendix-2 figures, tables and text support the geophysical context in this thesis, as follows:

(i) Section A2.1 describes and encloses pertinent information regarding the acquisition and

processing of the seismic 3-D cube used in this study.

(ii) Section A2.2 describes and encloses pertinent information regarding the seismic

interpretation; in particular, seismic resolution considerations as well as testing of the seismic

variance attribute (Chapter 3). Depth structure and time thickness maps are also enclosed

(Figures A2.6–2.11).

(iii) Section A2.3 shows the checkshot data and well-to-seismic tie information available to this

study (Tables A2.4–2.73). The checkshot data/plots provide gross depth-conversion

information for cross-sections and seismic sections enclosed herein; the data also forms a

fundamental input to the depth conversion performed in this study (Chapter 4).

(iv) Section A2.4 summarises secondary geophysical programs used in the UNIX environment.

(v) Section A2.5 pertains to input parameters, methodology and outputs resulting from the depth

conversion performed in this study (Chapter 4). Included are:

a checkshot plot for all wells, thus illustrating the regional spread (Figure A2.12);

the front-ends to the WitosoftC depth-conversion software (Figure A2.13);

depth-error plots for well groupings (Figures A2.14–2.19); these illustrate the limitations of

the depth conversion, and;

the polynomial file that has the TWT-to-depth information input to the WitosoftC depth-

conversion software (Table A2.74).

Appendix-3 figures, tables and text support the fault seal analysis performed in this study, as

follows:

tables A3.1–3.2 show the log availability as well as the petrophysical parameters input to the

PetroViewPlusTM software that generated the Vshale curves (Chapter 6);

the available in situ state of stress interpretations used in Chapter 7 are shown in Table A3.3;

figures A3.1–3.2 show frequency-of-occurrence histograms of the gamma-ray; these were

used to calculate sand and shale lines (Chapter 6), and;

the gamma ray-to-core comparison of four wells is shown in Figures A3.3–3.4 (Chapter 6).

The abbreviations that follow are used herein and will not be duplicated in figure and table captions.

(Chap oth Industry-based formation top data as well as

hiatus markers interpreted herein (Tables A1.17–1.95). The information in the ‘group’, ‘subgroup’ and

‘hiatus marker/formation top’ columns as well as the row colour scheme is compatible with the new

formation top/hiatus marker nomenclature. The process of iteration, elimination and verification was

used to ascertain the provenance and reasoning for inclusion of the formation tops and hiatus

marker data in the ‘Depth’, ‘TWT’ and ‘Source/remark’ columns of Tables A1.17–1.95. The process

is described below, in order of increased reliability.

(i) Formation tops were obtained from Partridge (1999), DPIVIC (2006), Geoscience Australia

(2006) and from individual WCRs. Any depth discrepancies noted were recorded and the most

reliable estimate taken; discrepancies were for the most part limited to a few meters. The low

level of discrepancy comes from the fact that both Partridge (1999) and DPIVIC (2006) worked

closely together, both being based in Victoria and closely associated with the Gippsland

Basins’ operators. Then, TWTs were estimated using checkshot data and subsequently cross-

checked against unconformities interpreted on the seismic data.

(ii) Age-depth plots were readily available from Geoscience Australia’s online petroleum

databases (www.ga.gov—data and applications, energy, applications, petroleum wells

applications) and these provided a quick and reliable estimation of key hiatus markers

(Figures A1.17–1.95).

(iii) Historically, palynological interpretations have been incorporated within Geoscience Australia’s

STRATDAT petroleum database (i.e. stratigraphic), with raw data originating from WCRs.

STRATDAT has its own language to precisely store well palynology including a dictionary for

all species zones and/or formations. The dictionary stores a maximum and minimum age

range for any one species zone as well as storing alternatives based on different age schemes

arkers prehensive tops database was set up based on a consistent nomenclature. Exploration wells

over 45 have resulted in formation tops recorded according to d

imination and verification was used to maximize and standardize formation tops across the well

ase as well as incorporate hiatus markers.

iatus markers were interpreted where possible and linked to seismic horizons; these were favored

reservoir or formation-based markers in or

hapter 1: Figure 1.3). The new formation top/hiatus marker nomenclature established in this study

and/or charts (e.g. in Australia Roger Morgan, Partridge (1999), Monteil (2006), ESSO

Australia in the case of Gippsland Basin data). Quality of confidence ratings is also stored,

where quality is dependant on: (i) the uncertainty of the ages stored in the dictionary; (ii) gaps

in the fossil record; (iii) non-linear rates of deposition; (iv) which parts of the data the program

honors and rejects, mainly based on the quality ranking; (v) which time-scale is used; (vi) non-

entry of repeat sections, and (vii) incorrect entries due to operator error.

(iv) Depths to hiatus markers were estimated by downward and upward extrapolation from known

formation tops and where geologically warranted: such markers are classed as ‘inferred’ in the

‘Source/remarks’ column. An example would be where a ‘top Kingfish Fm’ top was originally

reported from one of the above three sources, but where the term Mackerel Unconformity is

not used; in such a case, the depths are equivalent and the top renamed.

(v) If no formation tops existed or if hiatuses could not be estimated from age-depth plots, such

cases were coined as ‘no well info’. Formation tops could also be estimated as being absent,

coined ‘abs.’, where the seismic interpretation showed an interval as being eroded out. Such

cases occurred within the Tuna-Flounder, Marlin and Hapuku Channels. Lastly, a ‘?’ was used

to portray cases where the formation tops were expected to be present but no information was

available (i.e. no tops, age-depth, TWT).

(vi) The TWTs for all seismic horizons were interpreted and recorded at all well locations, even in

cases where tops were unavailable: such cases were coined as ‘interpreted on 3-D’ in the

‘Source/remarks’ column. If hiatus boundaries had coalesced, and could therefore not be

uniquely interpreted, TWTs were coined as being ‘inferred on 3-D’ in the ‘Source/remarks’

column. The TWTs were occasionally coined as ‘jump-tie’ where the well was located just

outside the seismic grid, if the location was too distant that case was labeled as ‘outside 3-D

grid’. Depths were obtained from checkshot plots and cross-checked against age-depth plots

so as to assure that the TWT interpretation was consistent with the palynology.

(vii) Increased levels of confidence in the formation top or hiatus marker pick were represented,

respectively, as ‘?’, ‘~’, ‘inferred on 3-D’, ‘interpreted on 3-D’, ‘inferred’, and the source quoted.

Depths obtained from checkshot plots, and cross-checked against age-depth plots, resulted in

as robust a way that was available to provide the highest number of formation tops and hiatus

markers from disparate datasets.

(viii) Markers within the Seaspray Group are fewer in number and not as reliable as the Latrobe

Group picks, because of the associated under-sampling of the palynology in the upper section.

282

283

Feary and Loutit (1998) carried out a seismic stratigraphy study of the Seaspray Group with a

total of 16 sequences interpreted along two transects; their TWTs were used for estimating

hiatus markers in the Seaspray Group. Their interpretation was also compared to Partridge’s

(1999) interpretation, where available, and with age-depth plots.

(ix) Markers within the Latrobe Group are deemed the most reliable, plentiful and most worked on

because of their association to petroleum-bearing reservoirs.

(x) Only TWTs are provided below total depth (TD); markers for the Golden Beach and Emperor

Subgroups and Otway Group, are less frequent.

(xi) Lastly, depths and TWTs of all volcanics intersected in wells are provided to enable

associations to be made with tectonic events.

A2.1 Seismic acquisition and processing The Northern Fields Gippsland Basin 3-D seismic survey was acquired between Oct. 2001 and Jul.

2002. The crossline direction of the seismic grid was orientated WNW–ESE, approximately parallel

to the main basin depocentre axis and major basin-bounding fault systems (e.g. Rosedale, Lake

Wellington). The sail-line heading (inline direction) is orientated at 18°N; acquisition and survey

navigation parameters are provided in Tables A2.1–2.2. The objectives of the survey were to identify

potential infill drilling programs, improve existing reserves estimation, ascertain any wildcat potential

and identify any deeper intra-Latrobe and Golden Beach exploration potential. More detailed

information regarding survey acquisition and processing can be found in WesternGeco (2002) and

Veritas DGC Asia Pacific Ltd (2002), respectively.

The bin coverage and specifics of the trace mix contained within each bin are particularly important

for attribute work. Long (2005) described the concept of illumination as ‘every subsurface point at the

target should have reflected seismic energy with a uniform distribution of source–receiver offsets and

azimuths’. The ideal situation is that each bin within the 3-D grid has the same number of recorded

traces for any one offset and azimuth distribution (Brown, 2004; Long, 2005). In the non-ideal

situation, seismic processing will compensate by sharing traces from adjacent bins, thereby

smearing temporal and spatial resolution. However, th

amplitude functionality of GeoFrameTM/IESX across the boundary was used to estimate the wavelet

(Figure A2.2d). Results are as follows.

i. The polarity and phase were checked at well locations where volcanic bodies are known

(Table A1.96). Results were inconclusive at Admiral-1, Kipper-1 and -2. Large positive and large

negative amplitudes were obtained flanked by low negative and low positive side lobes,

respectively. The seismic signature at the base of the volcanic body at Kipper-1 did, however,

correlate well with a quadrature phase wavelet having a -90º phase shift.

ii. The polarity and phase were checked at seismic locations where reflections are discordant with

layering (e.g. interpreted volcanic dykes/sills). Volcanic bodies are known to be present SSW of

the Kipper Field (O’Halloran and Johnstone, 2001). There, the phase ranged from -150 to -270º,

indicating that the wavelet was quadrature phase. The amplitude values clearly showed

asymmetry; small positive amplitudes were followed by large positive and intermediate positive

amplitudes. It was suspected that the discordant reflections might be representing the base of

the volcanic bodies, rather than the top, also in agreement with results found at Kipper-1.

iii. The polarity and phase were also checked at the water–rock interface for wells located in deeper

water (e.g. Volador-1, Pilotfish-1; Figures A2.2a–b), as results were inconclusive for wells drilled

in shallow water (~ 50–100 m). In the latter case, the fold is minimal as demonstrated from

calculating the critical angle; velocities assigned to near-surface sediments range from 1,700 to

2,000 m/s. The results confirmed the seismic data as associated with a quadrature phase normal

of separability and visibility are both dependant on the input source wavelet, bandwidth and phase.

The vertical seismic resolution is best defined according to a range of values because of the varying

conditions across the study area.

The power spectra and extracted wavelet were obtained at different locations within the study area

and depths within the seismic cube; the dominant frequency is extracted using GeoFrameTM ‘power-

spectra’ tool, which together with the interval velocity allows the wavelength to be estimated (Brown,

2001).

The average dominant frequency is estimated at the centre of each of the 15 location blocks and for

each of the six seismic intervals (Figure A2.3). The interval velocity was subsequently estimated in

order to calculate the wavelength λ . Checkshots were plotted for all wells within the seismic grid to

obtain the regional trend (see Figure A2.12), and a second order polynomial fit obtained (Equations

A2.1–2.2).

The interval velocity was calculated for each of the intervals where a dominant frequency could be

obtained. Calculating the limit of seperability (i.e. λ/4) for each of the intervals followed (EmpeSS,

GBeaSS, LHalSS1–2, UHalSS1–2, UHalSS3–CobiSS, SworSS). Estimates come to 55, 55, 35, 25,

25 and 15 m, respectively, for the mean-sea-level case (Figure A2.3) and are on average 10%

higher when datumed to subsea.

Variance attribute

Different operator lengths (i.e. 26, 52, 100, 200 and 400 ms) were trialed to maximise the fault trace

resolution (Figure A2.4). Shorter versus longer operator lengths can be used according to the level of

smearing of small-scale faults that is deemed acceptable, and the depth of investigation being

considered. A shallow slice of the seismic variance attribute (1,764 ms) is used to represent the

near-top Mackerel Unconformity while a deep slice (3,200 ms) is used for the near-base of

reflectivity. Tests were run in location block B8. Shorter operators (26 and 52 ms) give a noisier

spectrum and highgrade small-scale fault traces whereas longer operators (100 and 200 ms) higrade

longer fault traces: an operator length of 140 ms was deemed optimal to use across the study area,

deemed prudent to use the operator type ‘X’ so as to not bias the averaging of the variance attribute

to any one direction—differing fault trends are known to exist in the Gippsland Basin (Power, 2003;

Power et al., 2003).

The parameter testing of the seismic variance attribute indicated that an averaging operator type ‘X’

with an operator length of L = 140 ms was optimum. The number of traces to be used in the

averaging (3, 5, 7, and 9) was also tested: in all cases, a trace number of three gave the highest

resolution (Figures A2.4–2.5). The seismic variance attribute was subsequently computed across the

seismic cube using the above parameters.

2.4 Seismic workstation and software he seismic interpretation, carried out in the time domain, made use use of the GeoFrameTM/IESX

orkstation. The 3-D seismic data was imported as 8-bit format to contain the size of the seismic

project on the 300 Gb hard-disks provided—loading the seismic data as 32-bit was deemed

unwarranted in view of the research objectives, principally involving a structural interpretation.

The software Seismic ToolkitTM was used to read both the input and output SEGY headers from the

depth conversion. The software also allowed 3-D file volumes to be concatenated. The software was

written by Witold Severyn of PIRSA and donated for the purpose of this study.

The SeisView2TM software (freeware, version 2.25.4, released 2004) allows SEGY files (time or

depth domain) to be displayed prior to loading into the seismic workstation. The software was used

in conjunction with Seismic ToolkitTM to view the seismic sections (SEGY format) outputs from the

depth-conversion program ‘Depth-convert’ (WitosoftC software, see Chapter 4). The software was

written by Sergey Pavlukhin of Dalmorneftegeofizika Geophysical Company (DMNG) and is available

from the website www.dmng.ru/seisview/html/Eng.html.

Aspects of the depth conversion (WitosoftC software) and the fault seal analysis software

TrapTesterTM are described in chapters 4 and 6–7, respectively. Aspects of the depth conversion

program ‘Depth-convert’ are supported in Section A2.5 below.

A2.5 Depth conversion of SEGY and ASCII data Aspects of the depth conversion program ‘Depth-convert’ (WitosoftC software) are described below,

to the Witosoft depth-conversion software (Table A2.74).

Figure A2.13. The front-end menus for the program ‘Depth convert’ (Witosoftc software)—depth conversion of SEGY and ASCII data. (a) The menus ‘Segy T to D, ASCII D-to-T, ASCII T to D’ are used to depth-convert 2-D seismic data. The menus ‘Segy mpoly’ and ‘ASCII mpoly’ are used to depth-convert 3-D seismic data. The menu ‘Spline’ can be used for either 2-D or 3-D seismic data. (b) This front-end shows the input required for depth converting an offshore time-domain SEGY cube to the depth domain—the onshore option of the program is built-in but was not used here. The program requires the seafloor horizon to be input; it is depth-converts using a water velocity of 1,500 m/s. One polynomial function per well, representing the fit to the checkshots that is datumed to seafloor, is used and, all seismic datapoints are depth-converted according to a weighted-distance function. In addition, each seafloor grid point can be averaged (averaging distance). (c) The Polynomial functions are input together with the respective well latitude and longitude. A ‘max. time’ is input if one chooses the option do depth-convert using a constant velocity ‘max time velocity’ below the maximum time provided.

Table A2.74. Polynomial functions used for the depth conversion of SEGY and ASCII data. [Poly_????]—file name for each well. [Poly_TFC????]—Tuna-Flounder Channel. [Poly_MC????]—Marlin Channel. File format—easting/northing; polynomial coefficients (1st to 6th order)—t2d[1] to t2d[6]. Maxtime/mintime—generally taken just below well-TD if a constant velocity is used, if not maxtime = 5,000 ms. Maxvel—calculated from stacking velocities (also refer to Figure 4.2). Note 1: checkshot data from some wells (Athene-1, Basker-1, Blackback-1, Hapuku-1, Yellowtail-1 and -2) were not used as these are located outboard of other wells that adequately constrain the depth conversion. Note 2: a stacking velocity function was used for Wrasse-1 as the available checkshot data was incomplete. Note 3: a stacking velocity function was used in place of unavailable checkshot data for Trumpeter-1, Tuna-2 and Turrum-7; these wells are located within the 3-D seismic grid.

18BAPPENDIX 4—PUBLICATIONS ________________________________________________________________________________

A number of papers were published during the term of this Ph.D. study, as follows.

(i) Three papers were published during this Ph.D. but on a project that preceded this Ph.D.

(Sayers et al., 2006; Cinar et al., 2007, 2009)—the direction and contents of these works

formed part of the rational for conducting the research in this Ph.D. (i.e. understanding the

effect of faults on COR2R storage).

(ii) Two poster-abstract presentations were given at CO2CRC Research Symposiums held in

Western Australia and New Zealand (Sayers et al., 2007; Sayers et al., 2008)—these

symposiums were run by the organisation (CO2CRC) that financed this Ph.D. study; as

such, these works are unpublished.

(iii) Lastly, targeted components of Chapters 5–7 were presented and published as part of the

International Conference on Greenhouse Gas Technologies (GHGT-10) in Amsterdam,

Holland (Sayers et al., in press).
