Oct 12 (Reuters) - The U.S. oil drilling rig count rose this week for the first time in four weeks even as crude prices tumbled to their lowest in almost three weeks.
Drillers added eight oil rigs in the week to Oct. 12, bringing the total count to 869, General Electric Co's Baker Hughes energy services firm said in its closely followed report on Friday. RIG-OL-USA-BHI
The increase is the biggest weekly gain since mid August.
The U.S. rig count, an early indicator of future output, is higher than a year ago when 743 rigs were active because energy companies have ramped up production to capture prices that are higher in 2018 than 2017.
Since June, however, the number of rigs has stalled around 860 as the West Texas drillers that drove the shale revolution in the Permian basin have overwhelmed the region's ability to transport more oil out of the region via pipeline.
The Permian is the biggest shale oil formation in the United States.
Moody's analysts this week said takeaway capacity for oil and natural gas to markets outside the Permian is likely to be insufficient for the region's strong production growth until the second half of 2019 when new pipelines are expected to enter into service.
On Friday, U.S. crude futures were trading around $71 per barrel, putting the contract on track to fall for the first week in five due to a big rise in U.S. inventories and fading concerns about looming U.S. sanction s aimed at cutting Iran's oil exports.
So far this year, U.S. oil futures have averaged $67.14 per barrel. That compares with averages of $50.85 in calendar 2017 and $43.47 in 2016.
Looking ahead, crude futures were trading near $71 per barrel for the balance of 2018 and just above $70 for calendar 2019.
U.S. financial services firm Cowen & Co this week said the exploration and production (E&P) companies it tracks have provided guidance indicating an 18 percent increase this year in planned capital spending.
Cowen said the E&Ps it tracks expect to spend a total of $85.3 billion in 2018. That compares with projected spending of $72.2 billion in 2017.
Analysts at Simmons & Co, energy specialists at U.S. investment bank Piper Jaffray, this week forecast the average combined oil and natural gas rig count would rise from 876 in 2017 to 1,031 in 2018, 1,092 in 2019 and 1,227 in 2020.
Since 1,063 oil and gas rigs were already in service, drillers would only have to add a handful of rigs during the rest of the year to hit Simmons' forecast for 2018.
Year-to-date, the total number of oil and gas rigs active in the United States has averaged 1,021. That keeps the total count for 2018 on track to be the highest since 2014, which averaged 1,862 rigs. Most rigs produce both oil and gas.
The U.S. Energy Information Administration (EIA) this week projected average annual U.S. production will rise to a record high 10.7 million barrels per day (bpd) in 2018 and 11.8 million bpd in 2019 from 9.4 million bpd in 2017.
The current all-time U.S. annual output peak was in 1970 at 9.6 million bpd, according to federal energy data.
