Tinsley Field, Yazoo County, Mississippi: A Deeper Look at Mississippi's First Oil Field Using 3-D Seismic

Maurice N. Birdwell (1), Kevin B. Hill (2)

ABSTRACT

The first commercial oil production in Mississippi was established in 1939 at Tinsley Field with the completion of the Union Producing Company #1 G. C. Woodruff, Section 13, Township 10 North, Range 3 West, Yazoo County, Mississippi. Subsequent drilling in the 1940s and 1950s established oil production in the Eutaw and Upper Tuscaloosa, a formations. Cumulative production is more than 224.5 million barrels of oil and 15 billion ft3 of gas. The deepest wells drilled in Tinsley Field have been five wells drilled into the Smackover Formation. All of these wells reported gas shows but due to high H2S content or low permeability and low porosity, none were commercial completions.

Structurally, Tinsley Field is a large salt cored, faulted anti-cline. Large faults divide the field into three distinct producing segments. Recent deeper drilling (6,500 ft to 10,940 ft true vertical depth) on the north flank of the field by Hassie Hunt Exploration and Pennzoil has resulted in excellent oil and gas discoveries in the Hosston, Pine Island, Rodessa, Mooringsport and Paluxy formations. Current development is underway guided by a 3-D seismic program. The significance of the 3-D seismic is illustrated by the fact that no dry holes have been drilled in the development of these reservoirs.
