Pressured for profit, oil majors bet big on shale technology
Small oil companies have led the way in shale technology, turning US into world's fastest-growing energy exporter

HOUSTON, TEXAS:
Shale oil engineer Oscar Portillo spends his days drilling as many as five wells at once - without ever setting foot on a rig.
Part of a team working to cut the cost of drilling a new shale well by a third, Portillo works from a Royal Dutch Shell Plc office in suburban Houston, his eyes darting among 13 monitors flashing data on speed, temperature and other metrics as he helps control rigs more than 500 miles (805 km) away in the Permian Basin, the largest US oilfield.
For the last decade, smaller oil companies have led the way in shale technology, slashing costs by as much as half with breakthroughs such as horizontal drilling and hydraulic fracking that turned the United States into the world's fastest-growing energy exporter.

Now, oil majors that were slow to seize on shale are seeking further efficiencies by adapting technologies for highly automated offshore operations to shale and pursuing advances in digitalization that have reshaped industries from auto manufacturing to retail.
If they are successful, the US oil industry's ability to bring more wells to production at lower cost could amp up future output and company profits.
The firms could also frustrate the ongoing effort by The Organization of Petroleum Exporting Countries (OPEC) effort to drain a global oil glut. "We're bringing science into the art of drilling wells," Portillo said.
The technological push comes amid worries that US shale gains are slowing as investors press for higher financial returns. Many investors want producers to restrain spending and focus on generating higher returns, not volume, prompting some to pull back on drilling.
Production at a majority of publicly traded shale producers rose just 1.3 per cent over the first three quarters this year, according to Morgan Stanley.

But many US shale producers vowed during third quarter earnings disclosures to deliver higher returns through technology, with many forecasting aggressive output hikes into 2018.
Chevron Corp is using drones equipped with thermal imaging to detect leaks in oil tanks and pipelines across its shale fields, avoiding traditional ground inspections and lengthy shutdowns.
Ryan Lance, chief executive of ConocoPhillips - the largest US independent oil and gas producer - sees ample opportunity to boost both profits and output. Conoco also oversees remote drilling operations in a similar way to Shell.
"The people that don't have shale in their portfolios don't understand it, frankly," Lance said in an interview. "They think it's going to go away quickly because of the high decline rates, or that the resource is not nearly that substantial. They're wrong on both counts."
Shell, in an initiative called 'iShale', has marshaled technology from a dozen oilfield suppliers, including devices from subsea specialist TechnipFMC Plc that separate fracking sand from oil and well-control software from Emerson Electric Co, to bring more automation and data analysis to shale operations.
One idea borrowed from deep water projects is using sensors to automatically adjust well flows and control separators that divvy natural gas, oil and water.

Today, these sub-sea systems are expensive because they are built to operate at the extreme pressures and temperatures found miles under the ocean's surface.
Shell's initiative aims to create cheaper versions for onshore production by incorporating low-cost sensors similar to those in Apple Inc's watch, eliminating the need for workers to visit thousands of shale drilling rigs to read gauges and manually adjust valves.
Shell envisions shale wells that predict when parts are near mechanical failure and schedule repairs automatically. By next year, the producer wants to begin remote fracking of wells, putting workers in one place to oversee several projects.
It also would add solar panels and more powerful batteries to well sites to reduce electricity and diesel costs. Oil firms currently spend about $5.9 million to drill a new shale well, according to consultancy Rystad Energy.
Shell expects to chop that cost to less than $4 million apiece by the end of the decade. "There is still very little automation," said Amir Gerges, head of Shell's Permian operations. "We haven't scratched the surface."
Technology and geology
Much of the new technology is focused on where rather than how to drill. "There is no amount of technology that can improve bad geology," said Mark Papa, CEO of shale producer Centennial Resource Development Inc Anadarko Petroleum, Statoil and others are using DNA sequencing to pinpoint high potential areas, collecting DNA from microbes in oil to search for the same DNA in rock samples.

ConocoPhillip's MRI techniques also borrow from medical advances. ConocoPhillips next year will start using magnetic resonance imaging (MRI) to analyze Permian rock samples and find the best drilling locations, a technique the company first developed for its Alaskan offshore operations.
EOG Resources Inc last year began using a detailed analysis of the oil quality of its fields. The analysis, designed by Houston start-up Premier Oilfield Laboratories, helps to speed decisions on fracking locations and avoid less productive sites.
Premier has reduced the time needed to analyze seismic data to find oil reserves from days or weeks to seconds. Such efficiencies serve two purposes, said Nathan Ganser, Premier's director of geochemical services. "It's not only removing costs that are superfluous," he said. "It's boosting production."
