Model “AS1-X” 7K Mechanical Set Retrievable Packer



The AS1-X is the most versatile of the mechanically set retrievable packers and may be used in any production application. Treating, testing, injecting, pumping wells, flowing wells, deep or shallow, the AS1-X is suited. The packer can be left in tension or compression, depending on well conditions and the required application.

A large internal bypass reduces swabbing when running and retrieving. The bypass closes when the packer is set and opens prior to releasing the upper slips when retrieving to allow pressure equalization. The J-Slot design allows easy setting and releasing; 1/4 turn right-hand set, right-hand release.

The AS1-X  7K Mechanical Set Retrievable Packer has the ability to withstand pressure from above or below with differential pressures of 7,500 PSI.



·        Holds pressure differentials from above or below

·        Can be set using tension or compression

·        Only one-quarter right rotation is required to set and release

·        Field-proven releasing system

·        Optional safety-release features available upon request

·        Elastomer options available for hostile environments

·        Bypass valve is below upper slips so the debris is washed from slips when the valve is opened


·        Field-proven design is versatile; meets most production, stimulation, and injection needs

·        Can be run with a Model GT-2 On-Off Tool

·        Can be left in tension, compression, or neutral position

·        Bypass valve opens before upper slips are released

·        Ideal for use with fiberglass tubing


·        Effectively meets several requirements for zonal isolation, injection, pumping, and production

·        Full opening gives unrestricted flow and allows the passage of wireline tools and other accessories


A Small Oil Field In Oklahoma Is Seeing Big Bets From Producers

Monday, March 19, 2018
March 19 (Reuters) – A little-known shale oil play in Oklahoma is attracting more drilling and investment as rising output from newer wells is enticing companies to boost production beyond the giant Permian basin in Texas.
The Meramec formation is a part of what is called the STACK region – Sooner Trend Anadarko basin Canadian and Kingfisher counties – where companies such as Marathon Oil and Devon Energy bought up acreage following the oil slump in 2014.
Those investments are now paying off as production levels rise and soaring land costs in the Permian have producers looking to other fields for expansion.
Leading the pack is Oklahoma-based Devon Energy Corp, which expects its STACK production to reach 140,000 barrels of oil equivalent per day (boed) by the end of 2018, up from 107,000 boed a year ago.
Devon, also a Permian operator, said in a presentation earlier this month that it has earmarked more than 95 percent of its STACK budget for Meramec although it did not disclose dollar values.
Houston-based Marathon Oil Corp said last month it brought 26 wells online on a gross basis in the last quarter – nearly a third of all its new wells – up from 7 wells a year earlier. Its total production from Oklahoma rose to 64,000 boed in the fourth quarter, up about 42 percent over a year-earlier.
Smaller oil producers also are taking notice. Colorado’s Cimarex Energy said it is continuing to map the Meramec and move to development of its acreage there. Canada’s Jericho Oil also plans “tuck-in acquisitions” in the region.
“We are extremely encouraged with the results of … Meramec wells,” said Jericho Chief Executive Brian Williamson.

Competing With Permian

Low break-even prices and high output have contributed to rising activity in Meramec and the nearby Osage shale formation.
Completions rose to 170 in the final quarter of 2017, from just 18 at the start of 2015, according to data from exploration and production consultants Rystad Energy NASWellCube. The number of finished wells more than doubled over the last four quarters.
“Meramec/Osage not only compete with major liquid plays, they clearly belong to Tier 1 acreage,” says Rystad’s Per Magnus Nysveen, referring to leading basins like the Permian.
The U.S. Energy Information Administration (EIA) projects production from the Anadarko Basin, of which the STACK region is a part, to reach 493,000 bpd in April, still dwarfed by the more than 3 million barrels flooding out of the Permian basin daily.
But new-well production per rig in the basin is up 8.6 percent since August, compared with a 6 percent increase in the Permian, according to EIA data.
“There is a lot of upside … (Meramec) has proven to have results similar, and in some cases better, than the Permian,” said Taylor Cavey, an analyst at energy information provider S&P Global Platts.

Oil Prices Fall After API Reports Major Crude Build

The American Petroleum Institute (API) reported a huge build of 5.661 million barrels of United States crude oil inventories for the week ending March 2, according to the API data. Analysts had expected a build of 2.723 million barrels in crude oil inventories.

Last week, the American Petroleum Institute (API) reported a build of 933,000 barrels of crude oil. Last week’s API report showed a build in gasoline inventories of 1.914 million barrels.

Chevron Expects Up To 7% Production Growth In 2018

Chevron expects its 2018 net production to grow by between 4 percent and 7 percent at oil prices at $60 a barrel, the U.S. oil supermajor said in its annual security analyst meeting on Tuesday.

Last year, Chevron’s production was 2.73 million barrels of oil equivalent per day (boed), 5-percent growth over 2016, and this year and until 2020, Chevron believes it is “well-positioned to sustain this momentum.”

Arctic Oil Lease Sale Could Come Next Year

The first lease sale in the Arctic National Wildlife Refuge could take place as early as next year, Senator Dan Sullivan from Alaska said at CERAWeek. Officials from the Interior Department were in Alaska to study various aspects of the sale, which was stipulated in the tax reform bill that President Trump signed into law last December, S&P Platts notes.

The law obliges the Interior Department to hold at least two lease sales for the ANWR over the next decade, offering a minimum of 400,000 acres in total. However, there has been strong environmentalist and Democrat opposition to the stipulation. Opponents have pledged to fight the lease sales in the wildlife refuge by all legal means available.
