Polymer flooding review

This paper reviews published results of the use of polymers to improve oil recovery. A discussion of the capabilities of the available types of polymers and where they have been successful is coupled with the principles of the mechanisms of polymer flooding to serve as a guide for future applications. The scope of this review is limited to case histories where full-scale polymer floods were applied, as opposed to near-well treatments.

Analysis of the Kansas Hugoton Infill-Drilling Program

This paper uses official deliverability tests and production histories to compare the performance of infill wells and companion original wells drilled in the Kansas Hugoton field. In addition, the performance of one of the five Mesa replacement test wells drilled in 1977 in the Kansas Hugoton is reviewed. Pitfalls in the use of official deliverability and wellhead shut-in pressure differences between infill wells and companion original wells to indicate additional gas in place (GIP) are presented. Analysis of the performance of the first 659 infill wells has found no evidence of additional GIP.
