Houston, TX

In August 1997, Energy Spectrum made an initial investment in STRATA Directional Technology (“STRATA”), a Gulf Coast focused directional drilling and wireline company. Energy Spectrum’s equity provided STRATA with the means to expand their asset base platform and consolidate independent gulf coast directional drilling companies. In 1998, STRATA acquired Taylor Directional & Horizontal, Inc., a Gulf Coast provider of directional and horizontal drilling services. Also in 1998, STRATA purchased Production Well Testers, Inc., an offshore Gulf Coast-focused provider of well testing services. In early 2002, Allis Chalmers Corporation (“ACLM”), an oilfield services company, acquired STRATA. Energy Spectrum sold its interest in ACLM in 2004 and 2005.
