Case studies for Independent Producers
Air pulse system for artificial lift reduces costs

Ed Corlew and Joe Rochelle
In six months of testing at the Rocky Mountain Oilfield Testing Center (RMOTC), a unique air pulse lifting system, developed by Petroleum Asset Management Co. (PAMCO), lowered power consumption for lifting fluids in two shallow oil wells by 71%.
Company-operated, integrated, E&P waste management facility reduces costs

John Nussbaumer
An integrated, E&P waste management facility has reduced Patina Oil & Gas Corp.'s costs for processing oil-contaminated soils and fluids, including tank bottoms.
Major reserve increase obtained by dewatering high-water-saturation reservoirs

David Chernicky
New Dominion, L.L.C. has taken a bolder approach to developing major new reserves in exhausted oil and gas fields.
Nitrogen huff and puff process breathes new life into old field

Bernie Miller and Robert Gaudin
Using a nitrogen huff and puff (cyclic) process, Bretagne G. P. increased production from a mature Appalachian basin reservoir from 200 bopd to 500 bopd with no significant increase in water production.
Pilot test demonstrates how CO+B1625 injection enhances coalbed methane recovery

Lanny Schoeling and Mike McGovern
