Chestnut Petroleum has completed a work over project on the Layne #21 oil and natural gas well in Calcasieu Parish, Louisiana.

The well was initially completed in August 2006 with a flow rate of 57 barrels of oil per day and 1020mcf of gas per day.

Natural reservoir decline coupled with routine mechanical wear resulted in production dipping at the beginning of the year prior to rework, the company said.

Layne #21 is one of eight producing wells that Chestnut operates in the Gillis-English Bayou field in Calcasieu Parish, which sits at the westernmost edge of Louisiana, along the border with Texas and north of coastal Cameron Parish.

The Layne #21 work over was part of a larger field maintenance project that began in February 2010.
