Typical Stratigraphic Traps Jackson Trend of South Texas

Thomas S. West, Sr. (1)

ABSTRACT

The first significant oil production along the Jackson trend was in the Mirando Valley Field in Zapata County in 1921. Although exploration apparently reached the saturation point more than twenty years ago new fields continue to be discovered. Oil and gas accumulation is controlled primarily by stratigraphic traps resulting from the pinch out of some fifty separate sand members in an approximate 1800 foot interval in the Jackson and Yegua sections. Several thousand exploratory wells drilled during the past forty-two years have resulted in the discovery of some 250 oil and gas fields ranging in depth from 160 to 4000 feet. Fields range in size from Government Wells with over 86,000,000 bbls. of oil recovery to date to short lived one-well fields.

A detailed study of the Quien Sabe-Albercas area of Webb County provides type cases for each type of stratigraphic trap commonly existing along the trend.

Sands along the Jackson trend generally have relatively high permeabilities and porosities. Oil recovery per acre foot is usually in the 500 to 1000 bbl. range.
