Us Patents

Simultaneous Water And Gas Injection Into Earth Formations

US Patent:
5421408, Jun 6, 1995
Apr 14, 1994
Appl. No.:
Richard F. Stoisits - Anchorage AK
Miroslav M. Kolpak - Arlington TX
Gordon J. Krist - Anchorage AK
Tuan D. Ma - Anchorage AK
Richard L. Payne - Mckinney TX
Jeffry A. Rugen - Eagle River AK
Anthony C. Schwarz - Anchorage AK
Michael C. Vincent - Anchorage AK
Gary K. Youngren - Plano TX
Atlantic Richfield Company - Los Angeles CA
International Classification:
E21B 4316
US Classification:
Natural gas is reinjected into an earth formation for storage and/or stimulating the recovery of hydrocarbon liquids by mixing the gas with water at a pressure sufficient to maintain bubble flow of gas dispersed in a water flowstream in a range of volumetric gas fraction up to about twenty percent of total flow. A water and gas distribution system includes static flow mixers for maintaining uniform distribution of gas bubbles in the water flow stream through the distribution conduits. The mixers may comprise multi-stage bladed mixing elements of the same or opposite pitch and extending across the intersection of branch conduits with the main conduit of the distribution system. The water and gas may be mixed in an injection well having a tubing string extending within the well and having a distal end below the point of injection into an earth formation so that a uniform gas and water mixture enters the formation through the well perforations.

Automated Material Balance System For Hydrocarbon Reservoirs Using A Genetic Procedure

US Patent:
6128579, Oct 3, 2000
Aug 25, 1998
Appl. No.:
Michael D. McCormack - Plano TX
Donald J. MacAllister - Carrollton TX
Richard F. Stoisits - Plano TX
Perry W. Scherer - Harrison NY
Tuan D. Ma - Anchorage AK
Atlantic Richfield Corporation - Los Angeles CA
International Classification:
G01V 338
US Classification:
702 13
A system for producing a material balance solution for well patterns in a hydrocarbon reservoir is described that automatically optimizes the fluid allocation factors for each well used in determining the solution. The system automatically optimizes estimates for the allocation factors to be used in the material balance solution by randomly generating a first generation of allocation factor strings, each string in the generation assigning allocation factors to each of the wells in the reservoir. A fitness function value is determined for each of the strings by evaluating a fitness function, wherein the fitness function comprises the sum of the differences between computed and measured field pressures for each pattern, and the sum of the differences between target allocation factors and the allocation factors specified within the string for each well. A succeeding generation of allocation factor strings is produced according to a genetic algorithm. The process of determining a fitness function value for each of the strings is then repeated for the succeeding generation.
