Growth is set to decelerate sharply as the more recent slump in prices curtails new drilling and well completions.
The number of oil rigs went unchanged at 591, and gas rigs increased to 161 this week.
U.S. energy firms this week added oil and natural gas rigs for the first time in four weeks, says Baker Hughes.
A drop in gas prices has already caused some E&P companies to announce plans to cut some gas rigs to reduce production.
U.S. oil rigs fell by two to 590, while gas rigs dropped by two to 158, Baker Hughes announced on April 6.
Despite this week's rig decline, Baker Hughes said the total count was still up 82 rigs, or 12%, over this time last year.
The Permian led the nation in drilling rig activity in the past year, with data showing much of that growth coming from large, public upstream operators as private companies such as CrownQuest Operating, Iskandia Energy and Mack Energy have downshifted.
Even though gas rig counts are currently up, analysts say drillers have been cutting rigs in some shale basins, especially the Haynesville due to higher production costs.
Gas-directed rig activity in key U.S. plays, including the Marcellus Shale and Permian Basin, increased in a big way last week, but analysts expect cuts to the rig count later this year.
Oil rigs fell one to 589 this week, while gas rigs rose nine to 162.
