From Alberta, Canada, Central Second White Speckled Shale investigation can be seen, the use of wide-azimuth 3D seismic assessment of reservoir rock properties and the principal stresses the importance of In Western Canada Sedimentary Basin waters, wide azimuth D seismic can detect Red Deer, Alberta, a town southeast of 9 square kilometers (5.5 square meters) in a small area. This target area is the Cretaceous Colorado Shale Group, which is located in the Joli Fou weak shale layers and a large sandy Lower Cretaceous Mannville (Mannville) layer, while Manville layer is located above an unconformity, which does not strata beneath the unconformity mainly composed of carbonate rocks.
The results showed that about a quarter of the survey area as a fracture network shale fracturing, while the remaining major linear shale fracturing the fracturing or not, when considering the deployment and starting fracturing wells optimum position When this information is very valuable. If three-fourths of the exploration area is easy Hydraulic fracturing , then the cost of space is very large.
One well per square kilometer as the standard development of shale gas nine wells have to be drilled, the cost per well was $ 8,000,000, then the total cost of $ 72 million. The results show that reducing the two covering reservoir wells, you can save $ 16 million, the total cost of $ 56 million. This is easy to compensate for the cost savings provided by seismic data acquisition, processing and analysis of relevant information. Other economic benefits from drilling and completing most of the potential priority area, and the scale of development in the field of seismic data used in planning have added value.
