“We see significant tightness across the entire oil and gas value chain in North America” Oilfield services firm Halliburton Co. posted an 85 percent rise in first-quarter adjusted profit on Tuesday as a rally in crude prices boosted demand for its services and equipment. Crude futures climbed to their highest level in more than a decade during the quarter after a slew of Western sanctions against Russia disrupted oil sales from the world’s second-largest exporter. US West Texas Intermediate is currently around $106.95 a barrel while Brent futures are at $111.76 a barrel. The price increase has encouraged oil and gas producers to boost drilling activity, sending the US rig count to 673 at the end of the first quarter, up almost 15 percent from the fourth quarter of 2021, according to Baker Hughes data. Halliburton said margins in its Drilling and Evaluation division eclipsed 15 percent in the first quarter for the first time since 2010, despite weather and supply chain disruptions. The company anticipates the supply chain issues that have plagued the industry since demand rebounded from coronavirus-related lockdowns to continue. “We see significant tightness across the entire oil and gas value chain in North America,” Chief Executive Officer Jeff Miller said in a statement. “Supportive commodity prices and strengthening customer demand against an almost sold-out equipment market are expected to drive expansion in Completion and Production division margins,” he said, adding that he anticipates the company’s international business to grow throughout the remainder of the year. Halliburton also recorded a pre-tax charge of $22 million in the quarter for the write-down of its assets in Ukraine due to the ongoing conflict. The Houston, Texas-based company’s adjusted net income was $314 million, or 35 cents per share, for the quarter to March 31, compared with $170 million, or 19 cents per share, a year ago. Analysts had anticipated earnings of 34 cents per share for the first quarter, according to Refinitiv IBES. Shares were down about 2.3 percent in pre-market trading to $40.84 each. That outpaced a roughly 1.5 percent decline in US oil futures on Tuesday morning.
