A total of 836 kilometers (519 miles) of 2D seismic data was acquired by Gentech International Kazakhstan, LLP on Block XXXI-36 during the spring and early summer of 2008. The seismic data was acquired using an 8-90 Hz vibroseis sweep and a 240 channel recording system with a 25 meter group interval at 60 fold using a split spread recording geometry that produced a far trace offset of 3,012 meters. Final processed data is considered to be good to excellent quality for interpretation.
A total of eighteen (185) 2D seismic lines were acquired representing 836 kilometers of coverage This amount of seismic met the first year work program commitment for the block and provided an initial grid spacing of 2.5 km X 5.0 km. One line was extended north from the block boundary to tie well 2G which reported shows of oil in the Carboniferous carbonates. During acquisition the onsite data processing capability on the crew afforded Gentech geophysicists the opportunity to adjust the programmed lines to achieve optimum tie line positions on structures as observed on the field processed data.
Seismic Acquistion
Following a competitive bid tender, the seismic acquisition was contracted to Azimut Exploration Services JSC, a Kazakh geophysical contractor. Azimut mobilized their crew SP3/08 on the 9th of February 2008 from Korys, located approximately 300Km northeast of Block 36. Parameter tests were performed on the 28th of February, and production began on the 29th of February. It was recognized that the southeastern quadrant of the block comprises a low lying area near the Syr Darya and Karaozek rivers which might become flooded following winter snow melt. It was hoped that the ground would remain frozen long enough for the crew to traverse this area with the vibrators. Unfortunately, winter snow melt began to occur almost simultaneously with the mobilization of the crew. Even though production was slow at the beginning due to ground conditions, and was eventually suspended for 14 days (5-March until 18-March) due to snow melt and flooding, as the weather warmed and the ground dried out, production increased on the project. The final record was recorded on the 7th of June 2008 with 836 kilometers of coverage recorded in 100 days. There were no significant HSE issues or incidents during the course of the project.
Seismic Data Processing
The seismic data was processed by Hardin International Processors, Inc. in Dallas, Texas USA. During processing, careful attention was paid to the elimination of multiple energy that masked the true reflections at the top of the Carboniferous carbonate primary objective. The data was subjected to both pre-stack and post stack migration and after pre-stack migration, the data was stretched to depth using smoothed migration velocities along each line. The data was processed to a datum elevation of +100 meters using a correction velocity of 2,000 m/sec. Final data quality is considered to be good to excellent.
Seismic Interpretation
All final seismic data was loaded into the SMT Kingdom seismic workstation for interpretation. Since no well control exists for reflection identification, horizon names were assigned based on reflection patterns (unconformity) and reflection character of gross units (Carboniferous carbonates). These horizon identifications are tentative and subject to change once wells are drilled and logs can be tied to the seismic data via check shot survey, VSP and synthetic seismograms. In the interim it is useful to name the major reflection events with relation to the expected stratigraphic column in the area.
Four reflections have been mapped over the entire 2D data set. These horizons from shallow to deep are as follows:
- M. Cretaceous Marker – Black Horizon – (M_CRET)
- Unconformity – Yellow Horizon – (UNC)
- T. Carboniferous carbonates – Dark Blue Horizon – (CARB)
- T. Devonian sandstones – Brown Horizon – (DEVN)
Time structure maps were computer-contoured on the M. Cretaceous Marker (black) and Unconformity (yellow) horizons. Fault cuts intersecting the T. Carboniferous carbonates (dark blue) horizon were mapped and tied line-to-line. A time structure map on this horizon was hand-contoured due to the complex faulting observed at this level. This hand contoured map was then digitized into the computer for use in determining prospect sizes. Initial analysis of seismic velocities indicates an approximate 1:1 relationship between time and depth (ex: 1.000 sec ˜ 1,000 meters).
In addition to the time structure maps, interval isochron maps have been computer contoured for the following intervals:
- UNC-CARB – Indication of Top Seal Thickness
- CARB-DEVN – Indication of Carboniferous carbonate Thickness
