Oil Sands Imaging is proud sponsor of the January 23, 2012 CSEG Technical Luncheon
11.1.2012
CSEG Distinguished Lecturer Lee Hunt will present his talk Quantitative Interpretation, New Challenges, and Economic Value at 11:30am at the Telus Convention Center, MacLeod Hall C/D.
We invite you to attend this luncheon which promises to be both educational and thought provoking – see excerpts from the abstract below. For the complete abstract and to order tickets please go to http://www.cseg.ca/events/luncheons/2012/01jan/20120123-Hunt.cfm
We look forward to seeing you there.
Excerpts from the abstract:
Recent advances in drilling and completions technology, economics, and changes in our business models have been profound. These advances are overwhelmingly concerned with a quantitative description of material properties, stress, and azimuthal properties of our reservoir and its bounding materials. Surface seismic data can provide estimates of many of these variables…
My lecture will define and explain “quantitative methods”, their history, their value, their weaknesses, and why they are not only essential to tight reservoirs, but to all our efforts in effectively describing the earth. Quantitative methods are intimately related to the kinds of seismic data being used and the business purpose to which they are aimed, and so both need to be examined. This leads us first to a discussion of seismic data types and attributes, with an emphasis on some of the newer techniques and their related business problems. In particular, amplitude versus offset analysis (AVO), amplitude variation with azimuth (AVAz), velocity variation with azimuth (VVAz), curvature, and depth prediction will be discussed. Some of the quantitative work done on these attributes will be surveyed, including special challenges involved in relating them to the relevant geologic, engineering, or performance data that represent the business side of the problem.
Measurable value will be demonstrated from this approach in a number of ways. In particular we will follow the causal chain of the use of interpolation to produce better imaging, to obtain better AVO results, to achieve better drilling results, and to enjoy better economic results.
Converting seismic times to estimated depth is one of the oldest uses seismic has been put to, and with the need to steer horizontal wells within thin reservoirs or to avoid geo-hazards, the accuracy of these predictions has taken on a new meaning….I will demonstrate statistically the improvement in our ability to steer horizontal wells … and relate that improvement to production increases and economic advantage.
Quantitative interpretation is an extension or continued use of the scientific method by the oil and gas geoscientist, and forms a structure around which better decisions can be made.
