University, Government
& Industry Research Proves Natural Fractures Reduce Dry Hole Risk &
Increase Production
Government, University and
Industry research has proven that drilling on natural fractures zones
(also known as lineaments and photolineaments) can enhance oil and gas
production. This is done by increased secondary permeability and
porosity which allow for increased flow of hydrocarbons to the well
bore. A small sampling of quotes from the research is given below.
“In summary, this study has
shown that intelligent use of lineaments should significantly improve on
gas exploration results, with success rates of up to about double for
average wells in terms of yield” The Fourteenth Annual Appalachian
Petroleum Geology Symposium.
“Although gas well yield
gradually increases as a photolineament is approached, optimum well
yield is obtained only within 0.04 to 0.05 km (131-164 feet) of the
plotted photolineament line; this distance approximately corresponds to
the average plotting error for gas wells and photolineaments, suggesting
that one must locate a gas well directly on an optimum photolineament
for maximum potential well yield, and that the subsurface zone of
anomalously high permeability is vertically oriented.” U.S. DOE/METC/84-9,
1984.
‘the Gubik and Kavik gas
fields (Alaska) occur at the intersections of lineaments.: Oil & Gas
Journal, May 28, 1984.
“Of the seven gas wells near
a lineament and projected to be within about 29m (80 feet) of a deep
fracture zone anomaly, six wells produced at a higher than median yield
for final open flow, with yields ranging 1.0 to 8.7 MMCF/day compared to
a overall median of about 0.6 MMCF/day.” The Sixteenth Annual
Appalachian Petroleum Geology Symposium.
“Significant correlation was
made between high initial flow rates ranging from 4 mm to 27 mm cubic of
gas per day and fracture intersections, particularly in areas where
three or more fractures intersect.” Proceedings of the Second Workshop
on Remote Sensing/Lineament Application for Energy Extraction, U.S.
DOE/METC-86-6039, April, 1986.
“The company I was with at
the time of the big Austin Chalk play “proved” the play by showing the
Giddings area to be the site of intersections between two slightly
oriented linear trends.” Oil & Gas Journal, April 2, 1984.
“use of lineaments should
significantly improve on gas exploration results, with success rates up
to approximately double those for average wells” The Thirteenth Annual
Appalachian Petroleum Geology Symposium.
