Abstract

The Ken Regan Field, located in Northern Reeves County, Texas, was discovered in July 1954. Discovery was from Delaware (Olds) Sands at an approximate depth of 3,300 feet.

For the past twenty-nine years the field has experienced periods of active development followed by long periods of no activity. To date, the ultimate field limits have not been established and development continues.

The reservoir is a deep marine channel similar to, but slightly older than, the Ramsey Sand of the Upper Bell Canyon. Deposition of the Olds channel was from the northeast along the bottom of the basin. Subsequent eastward tilting has positioned the trap along the western boundary of the channel. Because of the irregularity of bottom floor topography, prediction of the channel direction remains a challenge.

Oil economics have played an important part in development of this field and many like it. Drops in oil prices can completely choke off development in “bread and butter” pays such as the Delaware Sand. In the long run the operators who do the best with the least expenditure will survive to continue to develop fields of this nature.

Ken Regan Field will be 30 years old in July 1984. It should continue to expand in size until the ultimate channel terminus is found or until economics preclude further drilling. Use of modern concepts of deep marine sedimentation has influenced much of the drilling which has taken place in recent years.
