East Mesa Reservoir

Abstract

INTERCOMP Resource Development and Engineering is currently working on contract to TRW Systems and the Bureau of Reclamation to provide petrophysical and reservoir engineering analysis of the East Mesa geothermal field. The twelve-month project was divided into three phases which consist of:

1. Analysis of current data and reservoir evaluation.

2. Design and execution of a long term flow test program.

3. Analysis of results and design of full scale reservoir development.

The first phase of the project is underway and portions of the work have been completed.

There are currently five wells drilled in the portion of the KGRA operated by the Bureau of Reclamation: 5-1, 6-1, 6-2, 8-1, 31- 1. Each of these wells has a complete set of geophysical logs run and a SARABAND analysis by Schlumberger is available on a 1 ft. increment. In addition, core analysis was obtained from the 5-1 well insufficient quantity to develop preliminary petrophysical transforms. Using the transforms developed in 5-1, INTERCOMP has performed a petrophysical analysis of the other wells to determine average reservoir properties over 250 ft. intervals. In particular, we determined $, h, kv and kh averages for each interval. To date there has been no geologic correlation established between any of the wells, so that property averaging by individual sand groups would not be meaningful.
