As the search for oil and gas reserves continues, exploration and production activities are occurring in increasingly harsh environments and drilling is going deeper than ever before. An experienced petroleum engineer is set to explain exactly how far this could extend – namely to Mars - at a Society of Petroleum Engineers (SPE) Aberdeen presentation and dinner meeting this month. Professor Alfred William Eustes III, a petroleum engineering and drilling specialist, will talk at the SPE Aberdeen monthly dinner and networking meeting on May 28.
