Petrophysical Investigation of the Secondary Recovery Potential in the Cherry Canyon Formation.

DE2004825150

Publication Date	2002
Page Count	36
Abstract	Read and Stevens has proposed the evaluation of the water flood potential from the Cherry Canyon formation in the NE Lea Field in lea County, New Mexico. Much of the development in this area is approaching primary recovery limitations; additional recovery of remaining oil reserves by water flood needs to be evaluated. The Cherry Canyon formation is composed of fine grained sandstone, containing clay material which results in high water saturation, and also has the tendency to swell and reduce reservoir permeability--the ability of fluid to flow through the rock pores and fractures. There are also abundant organic materials that interfere with obtaining reliable well logs. These complications have limited oil in place calculations and identification of net pay zones, presenting a challenge to the planned water flood. Core analysis of the Cherry Canyon should improve the understanding of existing well logs and possibly indicate secondary recovery measures, such as water flood, to enhance field recovery. Lacking truly representative core to provide accurate analyses, Read and Stevens will obtain and preserve fresh core. The consulting firm of T. Scott Hickman and Associates will then collaborate on special core analyses and obtain additional well logs for a more detailed analysis of reservoir properties. The log interpretation will be compared to the core analysis results, and the entire collected data set will be used to assess the potential and economic viability of successfully water flooding the identified oil zones. Successful results from the project will improve accuracy of log interpretation and establish a methodology for evaluating secondary recovery by water flood.
