Terrace Energy Corporation successfully completed a re-entry of an existing Eagle Ford Shale well on its 147,000 acreage in its Maverick County Project on August 8, 2013, announced David Gibbs, President of Terrace Energy Corporation.

Gibbs noted that “while our initial primary target continues to be the Pearsall Shale, this early result within our Maverick County Project point to the prospect of multiple formations over a surface area of 200 square miles. We expect the Maverick County Project to develop into a major area of operations for many years to come.”

The Eagle Ford Shale well known as the Chittim F-1H was initially drilled by a predecessor operator in 2011 and completed with 15 stages of hydraulic stimulation over a horizontal interval of approximately 5,000 feet. During its intial flowback testing, the Chittim F-1H well encountered operational difficulties and was temporarily shut-in.

After studying the Chittim F-1H well data and implementing a new drilling strategy, Black Brush Oil and Gas, the well’s current operator, successfully re-entered the well bore and began additional flowback testing on a tightly controlled choke. The Chittim F-1H well production was increased under careful control from initial rates of 30 barrels of oil per day to rates over 300 barrels of oil per day and 151,000 cubic feet of gas per day.

As a result of the successful re-entry, plans are underway to place the Chittim F-1H on an artificial lift and continue steadily increasing the flow rate of the well.

The importance of this Chittim F-1H well is the excellent flow characteristics that are achievable in this “black oil” window of the Eagle Ford Shale on the western side of play near the U.S.-Mexico border. This finding may open up a significant portion of the Maverick County Project to Eagle Ford Shale development.

Terrace Energy Corporation and the project operator plan to follow on the Chittim F-1H well with the drilling of another Eagle Ford Shale test well this fall 2013 including the evaluation of “Gas Frac” technology.
