Compressor. (open access)

Compressor.

Patent for a refrigerating machine compressor, which compresses more gas, cools the compressor with the incoming gas, and uses excess heat to dry the gas coming in.

Exploitation and Optimization of Reservoir Performance in Hunton Formation, Oklahoma Quarterly Technical Progress Report: January-March 2005 (open access)

Exploitation and Optimization of Reservoir Performance in Hunton Formation, Oklahoma Quarterly Technical Progress Report: January-March 2005

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 present the data on methane injection using huff-n-puff process. It appears that additional oil can be recovered using methane as a solvent. Additional experiments will be needed to confirm our analysis. Our engineering analysis has laid out detailed indicators to make the de-watering successful. Using those indicators, we are currently investigating potential in fill well locations in West Carney field. Our technology transfer activities continued this quarter with two presentations and one workshop.

Exploitation and Optimization of Reservoir Performance in Hunton Formation, Oklahoma Quarterly Technical Progress Report: January-March 2003

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. This behavior includes: (1) Decrease in WOR over time; (2) Decrease in GOR at initial stages; (3) High decline rates of oil and gas; and (4) strong hydrodynamic connectivity between wells. This report specifically addresses two issues relevant to our understanding of the West Carney reservoir. By using core and log data as well as fluorescence information, we demonstrate that our hypothesis of how the reservoir is formed is consistent with these observations. Namely, oil migrated in water wet reservoir, over time, oil changed the wettability of some part of the reservoir, oil eventually leaked to upper formations prompting re-introduction of water into reservoir. Because of change in wettability, different pore size distributions responded differently to water influx. This hypothesis is consistent with fluorescence and porosity data, as we explain it in this quarterly report. The second issue deals with how to best calculate connected oil volume in the reservoir. The log data does not necessarily provide us with relevant information regarding oil in place. However, we have developed …

Condition Survey: Altus Air Force Base, Oklahoma

"The purpose of this report is to present the results of a condition survey performed at Altus Air Force Base (AAFB), Oklahoma, during 14-17 May 1972. The three major areas of interest considered in this condition survey were the structural condition of the primary airfield pavements, the condition of pavement repairs and the types of maintenance materials that have been used at this airfield, and any detrimental effects of frost to the pavement facilities" (p. 1).
