Advanced Technology Improves Natural Fracture Prediction
November 19, 1998 (Pittsburgh, Pa.)
Small-scale microfracture analysis has been used to
predict large fracture distri-bution and conductivity. A new, inexpen-sive
technique using sidewall core has been proven effective in improving the
characterization of natural fractures of gas reservoirs in the Appalachian
Basin. Scaled microfracture analysis can now be mapped accurately and used to
predict quality of fractured reservoirs in areas of seismic anomalies and may
prove useful in locating additional reserves.

Exploiting
Tight Gas Sand Sweet Spots
April 26, 1999 (Denver, Colo.)
Reservoir characterization is needed to find sweet
spots in the eastern part of the Green River Basin’s tight gas reservoirs of
Wyoming. A wide variety of techniques were used to characterize fractures and
depositional facies, which are different for the Frontier Formation (Table Rock)
and the Almond Formation (Siberia Ridge). Fracturing appears most intensive near
several small faults or lineaments at both fields. However, its significance is
different for each setting. Permeability is enhanced by a factor of about two
paral-lel to east-west fractures.

Coal Bed Methane Development in the Midcontinent Area
June 3, 1999 (Wichita, Kan.)
Numerous coals in the Pennsylvanian section of the
Midcontinent area are appropriate to consider for coal bed methane (CBM) explo-ration.
The number of potential targets, cou-pled with the region’s industry
experi-ence in drilling and stimulation and its pipeline infrastructure, make
CBM opera-tions economically attractive. Activity has grown rapidly over the
last decade, but numerous CBM opportunities remain—especially for operators
who are willing to gather the information needed for identifying potential
reservoirs and to learn the technologies needed to produce them.

New Logging Tools and Techniques Key to Enhanced
Recovery
February 18, 1999 (Mt. Pleasant, Mich.)
and April 7-8, 1999 (Morgantown, W. Va.)
New tool technologies in wireline logging, analysis,
and interpreta-tion have advanced rapidly. Specialized tools can measure
reser-voir rock and reser-voir/ borehole fluid properties that were previously
unobtain-able. Also, the capability to accurately and efficiently collect,
analyze, and inter-pret the tool response data has greatly increased. Even for
operators with sub-stantial expertise in traditional wireline logging
technologies, it is difficult to stay abreast of the new advances that could
affect their bottom line.

Basin Analysis Aids Exploration in the
Mississippi Interior Salt Basin
July 21, 1999 (Jackson, Miss.)
The northeastern Gulf of Mexico has been explored
primarily by small- and medium-sized companies that typically do not have the
resources to analyze the vast amounts of data needed to perform basin analysis.
The University of Alabama recently conducted a compre-hensive analysis of the
Mississippi Interior Salt Basin to demonstrate the value of integrated basin
analysis.
The PTTC leaders brief DOE Fossil Energy officials on
results of tech transfer programs during a February 10th meeting in Washington,
DC. From left to right Bill Lawson, director of DOE National Petroleum
Technology Office; Lance Cole, PTTC Project Manager; Leo Schrider, PTTC Chair;
Guido DeHoratiis, Acting Deputy Assistant Secretary for Natural Gas and
Petroleum Technology; Deborah Rowell, PTTC Executive Director; Bob Kripowicz,
DOE Principal Deputy Assistant Secretary of Fossil Energy results have been made
available, along with implications for potential to signifi-cantly improve the
success rate of explo-ration wells in this area.
