West Carney field--one of the newest fields discovered in Oklahoma--exhibits many unique production characteristics. These characteristics include: (1) decreasing water-oil ratio; (2) decreasing gas-oil ratio followed by an increase; (3) poor prediction capability of the reserves based on the log data; and (4) low geological connectivity but high hydrodynamic connectivity. The purpose of this investigation is to understand the principal mechanisms affecting the production, and propose methods by which we can extend the phenomenon to other fields with similar characteristics. In our experimental investigation section, we continue to describe the use of surfactant to alter the wettability of the rock. By altering the wettability, we should be able to change the water-gas ratio in the reservoir and, hence, improve the productivity from the well. In our Engineering and Geological Analysis section, we present our rock typing analysis work which combines the geological data with engineering data to develop a unique rock characteristics description. The work demonstrates that it is possible to incorporate geological description in engineering analysis so that we can come up with rock types which have unique geological characteristics, as well as unique petrophysical characteristics. Using this rock typing scheme, we intend to develop a detailed reservoir description …

West Carney Field produces from Hunton Formation. All the wells produce oil, water and gas. The main objective of this study is to understand the unique behavior observed in the field. We would also like to extend the analysis to other similar fields. This report specifically addresses two issues relevant to our understanding of the West Carney reservoir. In the first part, we discuss our efforts to develop the geological model which can help us understand how the depositional environment affects the producing behavior. In the previous Budget Period, we described fourteen cores. In this report, we present preliminary analysis of several additional cores and conodont work. Based on the additional data collected, it is clear that the earlier geological model is simplified and needs to be updated. The complexity in geological environment can explain some of the unusual behavior observed in the field production. The second issue deals with how to develop a model for gauging a potential success of a dewatering project. We have a developed hypothesis regarding what makes it successful, however, we need to test it against the available data. We have started collecting data from other fields producing from Hunton formation so that we can …

Photograph of range management-uniform grazing. Soil Conservation Service [SCS] technicians recommended portable salt boxes such as this to be moved frequently to obtain uniform grazing by pulling cattle away from overgrazed areas to areas underutilized. Number 10 of a series. OK-858-12.

Photograph of an UNIDENTIFED worker on a tractor spraying the field for controlling weeds, native and tame pasture grass. The back of the photograph proclaims, "Pasture Management-Weed Control. Spray Rig consists of PTO Pump, tractor, barrels and boom costing approximately $250.00 being used to control weeds, native, and tame pasture. This practice highly recommended by the Soil conservation Service technicians, to reduce competition and increase stand of grasses. Native grass infested with ragweed's being sprayed with 2,4,D at rate of 1 lb. in 17 gallons of water per acre. Cost $1.20 per acre for material, labor and machinery – using tractor PTO Pump and Boom type sprayer."
