HOUSTON (Reuters) – Shale oil engineer Oscar Portillo spends his days drilling as many as 5 wells directly – with out ever setting foot on a rig.
A part of a group working to chop the price of drilling a brand new shale nicely by a 3rd, Portillo works from a Royal Dutch Shell Plc workplace in suburban Houston, his eyes darting amongst 13 screens flashing knowledge on velocity, temperature and different metrics as he helps management rigs greater than 500 miles (805 km) away within the Permian Basin, the most important U.S. oilfield.
For the final decade, smaller oil firms have led the way in which in shale expertise, slashing prices by as a lot as half with breakthroughs akin to horizontal drilling and hydraulic fracking that turned the US into the world’s fastest-growing power exporter.

Now, oil majors that had been sluggish to grab on shale are looking for additional efficiencies by adapting applied sciences for extremely automated offshore operations to shale and pursuing advances in digitalization which have reshaped industries from auto manufacturing to retail.
If they’re profitable, the U.S. oil trade’s capability to carry extra wells to manufacturing at decrease value might amp up future output and firm income. The companies might additionally frustrate the continuing effort by The Group of Petroleum Exporting Nations (OPEC) effort to empty a worldwide oil glut.
“We’re bringing science into the artwork of drilling wells,” Portillo stated.
The technological push comes amid worries that U.S. shale positive aspects are slowing as buyers press for increased monetary returns. Many buyers need producers to restrain spending and deal with producing increased returns, not quantity, prompting some to drag again on drilling.
Manufacturing at a majority of publicly traded shale producers rose simply 1.three % over the primary three quarters this yr, based on Morgan Stanley.
However many U.S. shale producers vowed throughout third quarter earnings disclosures to ship increased returns by way of expertise, with many forecasting aggressive output hikes into 2018.
Chevron Corp is utilizing drones geared up with thermal imaging to detect leaks in oil tanks and pipelines throughout its shale fields, avoiding conventional floor inspections and prolonged shutdowns.
Ryan Lance, chief govt of ConocoPhillips – the most important U.S. unbiased oil and fuel producer – sees ample alternative to spice up each income and output. Conoco additionally oversees distant drilling operations in an analogous strategy to Shell.
“The folks that don’t have shale of their portfolios don’t perceive it, frankly,” Lance stated in an interview. “They suppose it’s going to go away rapidly due to the excessive [production] decline charges, or that the useful resource will not be practically that substantial. They’re incorrect on each counts.”
Shell, in an initiative referred to as “iShale,” has marshaled expertise from a dozen oilfield suppliers, together with units from subsea specialist TechnipFMC Plc that separate fracking sand from oil and well-control software program from Emerson Electrical Co, to carry extra automation and knowledge evaluation to shale operations.
One concept borrowed from deepwater initiatives is utilizing sensors to routinely modify nicely flows and management separators that divvy pure fuel, oil and water. In the present day, these subsea programs are costly as a result of they’re constructed to function on the excessive pressures and temperatures discovered miles underneath the ocean’s floor.
Shell’s initiative goals to create cheaper variations for onshore manufacturing by incorporating low-cost sensors much like these in Apple Inc’s Watch, eliminating the necessity for staff to go to 1000’s of shale drilling rigs to learn gauges and manually modify valves. Shell envisions shale wells that predict when components are close to mechanical failure and schedule repairs routinely.
By subsequent yr, the producer needs to start distant fracking of wells, placing staff in a single place to supervise a number of initiatives. It additionally would add photo voltaic panels and extra highly effective batteries to nicely websites to cut back electrical energy and diesel prices.
Oil companies at the moment spend about $5.9 million to drill a brand new shale nicely, based on consultancy Rystad Power. Shell expects to cut that value to lower than $four million apiece by the tip of the last decade.
“There’s nonetheless little or no automation,” stated Amir Gerges, head of Shell’s Permian operations. “We haven’t scratched the floor.”
TECHNOLOGY AND GEOLOGY
A lot of the brand new expertise is concentrated on the place relatively than tips on how to drill.
“There isn’t a quantity of expertise that may enhance dangerous geology,” stated Mark Papa, CEO of shale producer Centennial Useful resource Growth Inc
Anadarko Petroleum, Statoil and others are utilizing DNA sequencing to pinpoint excessive potential areas, accumulating DNA from microbes in oil to go looking for a similar DNA in rock samples. ConocoPhillip’s MRI methods additionally borrow from medical advances.
ConocoPhillips subsequent yr will begin utilizing magnetic resonance imaging (MRI) to investigate Permian rock samples and discover the most effective drilling areas, a method the corporate first developed for its Alaskan offshore operations.
EOG Assets Inc final yr started utilizing an in depth evaluation of the oil high quality of its fields. The evaluation, designed by Houston start-up Premier Oilfield Laboratories, helps to hurry choices on fracking areas and keep away from much less productive websites.
Premier has lowered the time wanted to investigate seismic knowledge to seek out oil reserves from days or even weeks to seconds. Such efficiencies serve two functions, stated Nathan Ganser, Premier’s director of geochemical companies.
“It’s not solely eradicating prices which are superfluous,” he stated. “It’s boosting manufacturing.”
