Halliburton, the world’s largest oilfield hydraulic fracturing service provider, is experiencing a downturn due to weakening demand in the oilfield services market. The company is idling some of its oilfield equipment as shale companies reduce activity, leading to shrinking margins in its primary business line. Halliburton also anticipates pressure on business reactivation due to declining oil output rates in Mexico. The company forecasts a steep full-year revenue decline amid softer demand. Meanwhile, Exxon Mobil Corp. expects lower oil and gas prices to reduce its second-quarter earnings by approximately $1.5 billion, reflecting volatility in commodity prices. This outlook has contributed to a downturn in Exxon’s shares and broader challenges in the energy sector during the quarter.
