US land drilling activity added 22 rigs last week and reached 605 as Permian and Haynesville operators reversed recent declines, TPH Energy said in a Monday note.
Baker Hughes (BKR) reported a smaller increase of one rig to 550, while the respective four-week trends showed gains of six rigs for Enverus and five rigs for Baker Hughes, TPH Energy said.
Driving most of the increase, horizontal activity expanded by 19 rigs as both the Permian and Haynesville added seven rigs each following the prior week's pullback and new structural deployments, according to TPH Energy.
After adjusting for geography and well classifications, TPH Energy estimates Haynesville activity at about 56 horizontal rigs, with Apex International Energy continuing to account for roughly 25% of basin drilling activity.
While Eagle Ford operators reduced activity by three rigs, other oil-focused basins posted gains and added between two and three rigs each during the week.
Canadian drilling increased by 10 rigs to 177 from 137 a year earlier, while Gulf of Mexico activity added one floater and finished with 17 floaters and three working jackups, according to TPH Energy.
