Houston-based asset-brokers PLS Inc. and Burks Oil & Gas Properties Inc. have signed a partnership and joint-marketing agreement. Burks will move to PLS' corporate offices, downtown Houston, and each will market the others' services and work together on some assignments. Burks markets Gulf Coast properties and has handled some $2 billion in asset sales in the past 18 years, while PLS provides A&D information and asset-marketing. Both companies will continue to operate independently.
