ARKANSAS TURBIDITE STUDIES MAY AID OKLAHOMA JACKFORK EXPLORATION

摘要: During the past 2 years, more than a dozen successful Pennsylvanian Jackfork gas wells have been drilled in eastern Oklahoma, and play seems ready for expansion if drilling completion costs can be contained. To date, are thought to produce from fractures highly quartz-cemented, brittle sandstones. However, there is potential stratigraphic accumulations of gas. It generally agreed that Group rocks were deposited mainly as turbidites deepwater Ouachita basin. A recent suggestion significant amounts discontinuous less predictable sandy debris flows has received considerable critical review literature at 1996 American Association Petroleum Geologists convention. shallower water origin also suggested some outcrops Oklahoma. With this mind, authors provide summary their observations, measurements, interpretations upper southwest-central Arkansas guide interpreting subsurface
