US & Latin America

GreyStar Corporation was founded in 1995 in Houston, Texas to provide asset management services in the Gulf of Mexico. Following this, GreyStar Corporation expanded to provide the operation and maintenance of onshore and offshore platforms, oil fields and power generation facilities across North and South America.

In 2006, we merged with GreyStar, as our strong presence throughout Mexico, Venezuela, Colombia and Chile, provided a strong basis from which to service the whole of the Americas. Now trading solely as Penspen, we have a strong presence in the Eagle Ford Shale area of South Texas, as well as the Marcellus region in the North East and Bakken Shale region in the Williston Basin.
