It seems there is an ongoing supply of positive developments in the natural gas field in Texas that are poised to make our country more energy independent. Currently, almost all the fuel used to power hydraulic fracturing is diesel. Hydraulic fracturing is credited with much of the recent dramatic increases in Texas and US oil and gas production, but the industry required more than 700 gallons of diesel last year for this purpose at a cost of about $2.38 billion. If they could use natural gas, it would save the industry up to 70% and would allow the US to import 17 million fewer barrels of oil each year. There is a viable process in the works to make that possible.
Apache Corporation, with headquarters in Houston, Texas but that operates internationally, decided this was worth pursuing. Mike Bahorich, the vice president of technology, reached out to Halliburton and Schlumberger. Both companies told Mr. Bahorich that using natural gas to power hydraulic fracing was possible, but has not been due to the complexity of both the natural gas supply and the infrastructure. Both companies also told Apache that they would do a trial for Apache without cost.
So far, Halliburton is testing with liquefied natural gas. Its new system would build a simple gas line to the necessary engines by using a quick-connect jumper and would also allow for moving the line easily from job site to job site. Schlumberger is testing with compressed natural gas.
