The PTTC poster session"s theme is to illustrate a new method of technology transfer that was developed as a joint venture between the PTTC and World Oil magazine. The Petroleum Digest, a supplement to World Oil, was the vehicle developed for technology transfer of case studies to independent operators. Independents, in particular, rely on field-oriented case studies when they consider applying new technologies. PTTC supplies the case study technology results and World Oil publishes the case studies.

For illustration purposes of the newly developed technology transfer method between PTTC and World Oil magazine, the PTTC poster session will display four field case studies presented in the Petroleum Technology Digest, a supplement to World Oil Magazine. The Petroleum Technology Digest was first published in 1999, and it was distributed as a supplement to World Oil. Case studies are now being published directly in World Oil and distributed to more than 30,000 readers. PTTC is making periodic reprints available. There have been four publications to date.

Case studies are authored by producers or, if a technology supplier is involved, both the producer and technology provider are co-authors. This enhances credibility of the published field performance. Unlike typical professional society papers, the case studies contain sufficient economic data to enable producers to make their own decision regarding the technology's applicability to their situation.

These four case studies reflect technology used and/ or developed in the Permian Basin (Texas and New Mexico), and in the Four Corners area of New Mexico. The four case studies with an individual poster for each are:

Bottom Line

Since 1994, Devon Energy Corp. has employed the Vapor Jet system to capture hydrocarbon vapors from oil and water storage tanks in a West Texas waterflood operation. The system has proven to be a reliable, flexible, cost effective alternative for capturing hydrocarbon vapors to increase gas sales, while reducing hydrocarbon emissions.

Bottom Line

Since 1995, Burlington Resources has been conducting a pilot test of enhancing coalbed methane recovery through carbon dioxide injection. The objective of the CO2 injection pilot is to accelerate recovery, displace methane with CO2 and recover incremental reserves. To date, 4.7 Bcf of CO2 has been injected with only limited CO2 breakthrough. Since primary production was increasing throughout most of the period due to dewatering, lowering of backpressures and well stimulations, reservoir simulation was an essential tool in analyzing pilot performance. It is estimated that injection to date will yield 1.6Bcf of incremental reserves.

Bottom Line

Operators in the huge Indian Basin field have found that significant volumes of gas can be produced far behind the encroaching water front by pumping large volumes of water along with the gas. Yates Petroleum, one of the early users of this "secondary-gas" technology, is producing about 38 MMcfd from a two- section area where the carbonate reservoir lies 200 ft below the current water-gas contact.

Bottom Line: Using the walking beam-operated Beam Gas Compressor, operators can increase production and reduce operating costs on rod pumping wells by drawing gas and gas pressure from the casing to allow additional hydrocarbon flow. Incremental daily revenue in five wells ranges from $100/day to $360/day—a particularly significant increase for often marginal wells.
