Summary
Seismic objectives addressed during the fourth quarter concerned seismic recognition of Grayburg carbonate porosity and development of maps of the distribution of seismic properties which can be related to reservoir porosity. Synthetic seismograms representing various porosity combinations for the Grayburg A sequence were interpolated in forward models to demonstrate waveform character, and a seismic inversion model was used as the basis for work with seismic-guided attribute maps which have been instrumental in defining porosity within the upper Grayburg. The geologic objectives addressed during the quarter were the integration of the geologic model into the 3D to accurately portray the lithologic markers, the coring and logging of the Witcher {number_sign}12, and working toward the development of a successful completion technique for the lower Grayburg and San Andres. Considerable effort went into developing a usable seismic velocity/log porosity transform. There were a number of engineering objectives this quarter. The development of a successful completion technique for the lower Grayburg and San Andres which would contact the maximum volume of reservoir, minimize potential water production, and be cost effective was a high priority. The Witcher {number_sign}12 was drilled, and Foster-Pegues {number_sign} 4 re-entered and converted to injection this Quarter. The first steps in the quantitative integration of seismic data into the reservoir simulation were taken this quarter. Work on water quality, buildup and fall off tests and the update of production and injection data in the model was ongoing.
