Royal Dutch Shell Chief Financial Officer Jessica Uhl said on Wednesday wages and services costs in the oil and gas industry around the world have started rising following a deep downturn since 2014.
"We are seeing wage inflation and inflation effecting the supply chain and we are actively managing it," Uhl told reporters in a conference call following the company's third quarter results.
"It is certainly getting a bit tougher than it was a year or two ago."
Service costs around the world plunged following the 2014 oil price crash and have been slow to recover despite crude prices surging to four-year high last month.
