In the Permian Basin, carbonate rocks have high sonic velocities and are commonly buried quite deep, making three-dimensional seismic useful for reservoir understanding, but certainly not definitive. Therefore, 1-D well data such as wireline logs and cores must be used to make a 3-D sequence stratigraphic interpretation. The concepts of sequence stratigraphy are well understood but sometimes difficult to apply. In this hands-on course, we looked at several examples of carbonate reservoirs in the Permian Basin and attempt to apply "rules and tools" to get the most accurate 3-D interpretation from the available 1-D data. The morning consisted of lectures on high-frequency sequence stratigraphic concepts using Permian Basin examples, and the afternoon focused on a few simple exercises to give attendees hands-on experience interpreting 1-D data sets. The core portion was co-instructed by Denise Cox. 6 RLP/CPL recertification.
