Abstract

The objective of this presentation is to share some of the decision processes that routinely go into seismic interpretation that can enhance and provide critical insight into resource plays. As the Oil industry moved mainly from conventional structural and stratigraphic plays on shore into shale and resource plays, we have once again encountered the age old historical reservations of the necessity and value added in the acquisition of new 3-D seismic data. What I plan to share with you today are some of the techniques, tools, and some of the pitfalls I’ve encountered on data sets in the Permian Basin Wolfberry Play and in the Eagle Ford Play of South Texas. Today’s presentation will show a Permian data example on recently encountered geohazards which caused significant drilling problems at shallow depths of 2700’ that can be identified on seismic and geohazards examples in the Eagle Ford. I’m fortunate that the company I work for Fasken Oil and Ranch has a strong acreage position in both of these plays and currently is not acquiring any additional acreage, therefore they have allowed me to show you data sets that are being used right now in our drilling program.

• Choosing the Proper Data Set for Interpretation- Inversions, Coherency, Bandwidth extended data

• Geohazards-Air pockets in shallow drilling Midland Basin, Shallow faults in San Miguel causing mud weight increase and losts

• High-Grading Drilling Locations and Horizontal Drilling-Seismic Examples around the C-Ranch in Wolfberry B, Cline, and the Eagle Ford

• Displaying your Data and Living in the Depth World-Microseismic and depth sections
