Parker Drilling Company (NYSE:PKD): Parker Drilling said, “Our business outlook remains driven by the growing needs for the services, operational efficiency and safety we deliver to our customers. Though there are concerns about the impact of low domestic natural gas prices on U.S. drilling, the shift to oil and liquids-rich directed drilling continues to require a growing amount of drill pipe and related equipment. In addition, oil-directed drilling continues to sustain activity in the coastal waters of the Gulf of Mexico. The industry’s increased spending to develop oil and gas resources worldwide is expected to lead to more drilling activity and an expanded reach into challenging environments that require fit-for-purpose drilling solutions. We believe these trends will benefit Parker’s U.S. and international operations.”
