Drilling Activity Summary
Description
Noble Energy Inc., according to IHS Markit, completed two horizontal producers that were drilled with flattened-wave-like horizontal laterals through a number of thin zones, including Niobrara, Fort Hays, Codell and Carlile. The ventures are in Section 17-5n-63w of Weld County, Colo., on the western flank of the Denver-Julesburg Basin. The #18 BB-681 70 Ranch-State initially flowed 805 bbl of 52-degree-gravity oil/condensate, 781 Mcf of gas and 200 bbl of water per day. Production is from a horizontal lateral extending from 7057 ft westward to 16,023 ft at a bottom-hole location in Section 18-5n-63w. True vertical depth at the well’s endpoint is 6,796 ft. Perforations in the flattened-wave-like lateral are as follows: 7,210-8,093 ft (Fort Hays); 8,094-8,872 ft (Niobrara); 8,873-8,906 ft (Fort Hays); 8,907-9,015 ft (Niobrara); 9,016-10,404 ft (Fort Hays); 10,405-10,670 ft (Codell); 10,671-10,949 ft (Fort Hays); 10,950-11,051 ft (Niobrara); 11,052-11,938 ft (Fort Hays); 11,939-12,639 ft (Codell); 12,640-12,693 ft (Fort Hays); 12,694-12,757 ft (Codell); 12,758-12,812 ft (Fort Hays); 12,813-13,044 ft (Codell); 13,045-13,050 ft (Carlile); 13,051-13,222 ft (Fort Hays); 13,223-13,916 ft (Codell); 13,917-14,077 ft (Carlile); and 14,078-15,213 ft (Fort Hays). Tested on an 18/64-in. choke following 35 stage fracturing between 7,210 and 15,213 ft, the flowing tubing pressure was 1,190 psi and the flowing casing pressure was 1,807 psi. The operator noted they “did not hit the Codell until much farther down the lateral” and they “didn’t penetrate the Codell in the curve.” Within a quarter mile to the south, #18 BB-662 70 Ranch-State was completed as a flattened-wave-like horizontal lateral producer in Niobrara, Fort Hays and Codell initially flowing 788 bbl of 50-degree-gravity oil/condensate 789 Mcf of gas and 312 bbl of water daily. Production is from a horizontal lateral extending from 7,050 ft westward to 16,027 ft at a bottom-hole location in Section 18-5n-63w. True vertical depth at the well’s endpoint is 6,761 ft. Perforations in the flattened-wave-like lateral are: 7,229-8,787 ft (Fort Hays); 8,788-9,356 ft and 9,357-9,678 ft (Niobrara); 9,679-11,240 ft (Fort Hays); 11,241-12,121 ft (Codell); 12,122-12,413 ft (Fort Hays); 12,414-12,934 ft (Codell); 12,935-13,000 ft (Fort Hays); 13,001-13,382 ft (Codell); 13,383-13,530 ft (Fort Hays); 13,531-13,847 ft (Codell); 13,848-14,040 ft; 14,041-14,189 ft (Niobrara); 14,190-15,218 ft (Fort Hays) and 15,219-15,931 ft (Codell). It was tested on an 18/64-in. choke following a 38-stage fracturing between 7,229 and 15,931 ft with a flowing tubing pressure of 1,562 psi and a flowing casing pressure of 1,962 psi. Like #18 BB-681 70 Ranch-State, Noble reported that #18 BB-662 70 Ranch-State also did not hit the Codell until much farther down the lateral. Noble is based in Houston.
