Seismic Interpretation and Reservoir Prediction |
|
1. Outline
Under the guidance of geological theory and with integrated application of geological, drilling, logging and oil testing data, multiple geophysical techniques are matched reasonably to accurate seismic interpretation and reservoir prediction. For the goal of predicting favorable traps precisely, looking for high-quality exploration targets and helping customers to achieve stable yields and increase production, The V-petrotek,LLC set up a team of technical experts with extensive experience, can provide professional and high-level services for customers.

2. Service Contents
On the basis of fully understanding the regional geological setting, 2D and 3D accurate seismic interpretation results from precise synthetic seismogram and velocity analysis, using multiple geophysical methods to identify fault distribution and reasonable fracture system combination, and study of the structural feature and fault sealing characteristic. Simultaneously, defining the favorable facies of reservoir development by seismic facies analysis, analyzing the reservoir distribution by multiple seismic attributes, and describing reservoir thickness and distribution by log constrained inversion can find favorable traps and reliable exploration targets. |
3. Technology Roadmap |
|
4. Key Technolog
(1) Accurate Structural Interpretation Techniques
Using fine synthetic seismogram calibration, 3D volume interpretation and visualization techniques, structural feature and fracture system combination can be described, and favorable traps can be predicted.
|
|
(2) The Technique of Carbonate Seismic Reflection Mode Recognition and Evaluation
Dominated by seismic reflection characteristics, based on drilled reservoir types and karst development and exploitation characteristics, the reservoir with different seismic reflection mode can be automatically identified by self-prepared software on computer. Combined with geological interpretation, palaeogeomorphology and current tectonic position, the favorable target area of the identified reservoir can be evaluated and optimized.
|
|
(3)The Geostatistics Inversion Technique
The geostatistics inversion technique can clearly identify the multiple sets of reservoir between two seismic event with high accuracy by absorbing the changed information of seismic data in the transverse direction. |
|
5. Typical Cases |
Since 2006, the company has successfully completed seismic interpretation and reservoir prediction projects of more than ten different types of reservoir of Shengli Oilfield Branch, Sinopec, Tarim Oilfield and Karamay Oilfield Branch, CNPC, etc. |
‘The study of carbonate seismic reflection mode recognition and exploitation countermeasures in Tarim Oilfield xx Block’: The project research ideas, methods, and results of the carbonate reservoir seismic pattern recognition, evaluation of favorable reservoir prediction and exploitation countermeasures obtained the approval.
‘Three-dimension seismic fine interpretation and Reservior Prediction of CNOOC’s xx field’: the basis for further development deployment is provided for reservoir exploration and evaluation by multi-well constrained inversion.
‘The Special lithology (dolomite) reservoir identification of the lower Partofmember 1 of Shahejie Formation in Qinan Depression of Dagang Oil Field’: Based on the dolomite log reconstruction technique, the ultrathin dolomite reservoir is predicted accurately by geostatistics inversion.
