Morrow Sandstone Well Completion Practices

Because of the susceptibility of the Morrow Sandstone formation to fluid damage, improved completion techniques have been demanded by industry. A new look at old ideas has resulted in the development of unique procedures especially adapted to well completions in sensitive dry-gas sandstone reservoirs. In this paper is presented a historical account of the development of completion practices in Morrow wells located chiefly in Eddy and Lea Counties, New Mexico. Special emphasis is given to the Tubing Conveyed and the Maximum Differential techniques developed by Vann Tool Company.
