2.1. Data Acquisition

2.1.1 Geological Data

The Khmer Basin is elongate and oriented in north-south direction situated between the Khmer shelfto the east and the Central Basin High to west. The basin is approximately 200 km long and 100 kmwide. The thickness of the Tertiary sedements is estimated up to 7,000 meters in the center of the basin.

1.4 Interpretation/Regional Reports (books)

- Report on Seismic Interpretation (Enterprise).

- Interpretation Reports of 3D Survey Block I & II of Offshore Cambodia (Enterprise).

- Regional Study on Petroleum Geology the Extended Area of Block ( Campex).

2.1.2.a 2D Seismic

During 1992 Enterprise acquired 7344 km of 2D seismic data, Split as follows:

3079 km in Block I, 3352 km in Block II and 913 km of regional data in Block III and IV.

The data was acquired by HGS and provided a 2.5 x 2.5 km grid over Block I and II,

and a 20 x 20 km grid over block III and IV. The data was processed by Ensign between

June and October 1992. In addition, Enterprise traded seismic data with Campex to gain

a further 3600km of 2D data over Block III.

By the end of 1998 Woodside Petroleum (Australian Company) was awarded PSCs

for offshore blocks 5 & 6. Woodside acquired 5 000 km of 2D seismic lines.

2.1.2 Geophysical Data

Prior to acquisition of the EO92CB06 survey Enterprise‘s Seismic database over Block I andBlock II consisted of some 800 km of data acquired by Elf during the early 1970’s.

2.1.2.b 3D Seismic

The 2D dataset was considered in adequate for detailed mapping of complex structures foundalong the mergins of the Khmer Basin. The way forward was identified to be the acquisitionof the 3D survey was part of the work commitment for a first licence extension.

The 3D survey was acquired by the vessel M/V Western Atlas between 9 October 1994 and2 December 1994. It covered 860 km2 and comprised over 35,000 subsurface line km of data,creating a normal 40 fold cube of data, with a crossline seperation of 25 m and an in linespacing of 12.5m.

As a result, a total nine Wells were drilled and about 13 675.150 km of 2D seismic lines and1050 km2 of 3D seismic survey were acquired and processed in these offshore blocks by thosecamponies during 1990-1997.

2.1.2.c Gravity and Magnetics

7275 km of marine gravity and 7406 km of marine magnetics were acquired by Edcon inconcurrence with the EO92 survey. The gravity and magnetics data were processed by ARKGeophysics.

2.2 Technical Work Done by CNPA

2.2.1 Seismic Interpretation (Time Contour Map)

During 1997 DGM (Department of Geology & Mines) was acquired 2D Seimic Data

Interpretation Workshop from February 22 to October 15, 1997. This Workshop was

conducted by Mr. TETSUEI TOYAMA (Idemitsu Oil & Gas Co., Ltd). The main of

this interpretation is using actual data in block I & II on 58 lines and 4900 km2 and also

completed contour map in the both blocks.

2.2.2 Well Planning

At the same year above DGM had to make one more Well Planning Workshop from

January 06 to August 06, 1997. Mr. FURUTANI conducted this Workshop (Idemitsu

Oil & Gas Co., Ltd). This Well Planning was planned to drill in block IV And named

well X.
