Mr Zimmerman replaces current CEO Murray Conradie who will continue in a strategic advisory capacity to ensure a smooth transition. The company has also elected Michael Pawelek as its new chairman and outside director to replace Mr Conradie who is resigning from the board of directors.
Mr Pawelek, a geophysicist, has held senior management positions throughout his 27-year career in the exploration and production and oilfield services industries. After working south Texas fields early in his career, Mr Pawelek later served as CEO of Universal Seismic Associates, a seismic acquisition and processing company that later became publicly traded and ultimately sold.
Scott Zimmerman, president and CEO of South Texas Oil, said: Our management and board changes mark our transition from a development stage company to that of an exploration and production company with quality projects, growing production and further potential over its leasehold.
