7 Oxford, Kans., independent W.D. Short Oil Co. LLC completed a 100-bbl.-per-day oil producer on the Nemaha Uplift about two miles southeast of Oxford, Kans. The #3C Carson is in Section 19-32s-3e of Cowley County and produces from Arbuckle perforations at 3,416-18 ft. No water production was reported at the 3,500-ft. well. Slick-Carson Field was discovered in 1924 and produced 4.5 million bbl. primarily from Arbuckle, with secondary pays in Layton and Bartlesville.

8 Chesapeake Operating Inc. of Oklahoma City recorded an initial flow rate of 8.03 million cu. ft. of gas, 89 bbl. of condensate and 17 bbl. of water per day.

The company’s #4-4H Blair Farms, in Section 4-14n-4w, Oklahoma County, produces from two open-hole laterals drilled to bottomhole locations to the west. One leg was drilled to 8,238 ft. and terminates in Section 5-14n-4w (true vertical depth, 6,722 ft.). The second leg is a 10,050-ft. lateral (true vertical depth, 6,712 ft.) that ends in Section 5. Additional production details are not available.

12 A Stephens Production Co. well, #1-16 Fort, flowed 1.69 million cu. ft. of gas daily at the second workover of an Arkoma Basin well in Section 16-7n-31w in Sebastian County, Ark. The gas well was originally completed in 2000 and produced gas at an unreported rate from Middle Hale at 7,388-7,422 ft. A second reentry by Fort Smith, Ark.-based Stephens in 2005 added perforations at 8,058-8,104 ft. in Penters. During the latest reentry, the company added perforations in Lower Carpenter below 3,703 ft. and tested the well producing commingled gas with the Middle Hale. Prior to the new operation, the 8,221-ft. well had recovered 2.38 billion cu. ft. of gas and was averaging approximately 295,000 cu. ft. daily.
