Although exploration and drilling is down due to low oil and gas prices, players in Oklahoma’s Scoop and Stack plays still seem committed to developing the resource.

While Marathon Oil Corp.’s (NYSE: MRO) 2016 budget is about half of what it was in 2015, the company plans to spend about $200 million to support 20 to 22 gross company-operated wells to sales. An average of two rigs in 2016 will focus primarily on lease retention in the Stack and delineation of the Meramec.

In the Scoop/Springer, Marathon plans to complete its second company-operated well this year and drill another well later in 2016.

Continental Resources Inc. (NYSE: CLR) plans to spend about 15% of its capex on Stack and about 7% on the Northwest Cana joint development area (JDA). Continental anticipates an average of 19 operated drilling rigs for 2106, with five to six rigs in Scoop, five in Northwest Cana JDA and four to five in Stack.

Based on early production from recent Continental completions and other nonoperated wells in the over-pressured Meramec oil window, the company is estimating an average estimated ultimate recovery of 1.7 million barrels of oil equivalent (MMboe) per well with an operated well cost of $10 million for a 9,800-foot lateral producer.

Additionally, Gastar Exploration Inc. (NYSE: GST) sold some of its Appalachian Basin assets to focus on the Stack play to emphasize exploration and development its acreage.

An extended-reach horizontal producer completed by Denver-based Felix Energy LLC produced 1.645 thousand barrels (Mbbl) of 42-degree-gravity oil, 1.72 million cubic feet (MMcf) of gas and 1.09 Mbbl of water per day.

The #1AH Showboat 1003 is in Section 10-16n-9w of Kingfisher County, Okla. Production is from a fractured Upper Meramac zone at 9,186 feet to 18,942 feet.

4. Continental Resources: 2/3/16

A Criner Hills Uplift-Woodford well in the Scoop Play has been completed by Continental Resources.

The extended-reach horizontal discovery, #1-11-2XH Gentry, is in Section 11-3s-4w of Stephens County, Okla. According to IHS, it was tested with 10,128 feet of completed lateral flowing about 14.5 MMcf of gas and 425 bbl of condensate per day.

The proposed 25,247-foot prospect was designed with a northerly wellbore terminating in Section 2-3s-4w. No further completion details were available.

5. Newfield Exploration: 10/9/15

In Newfield Exploration Co.'s (NYSE: NFX) Scoop area, the company reported the completion of a high-volume Anadarko Basin-Goddard (Lower Springer Shale) well.
