Union Pacific Resources Inc., Fort Worth, hopes to start gas production in mid-2000 from underdeveloped Klua field in a remote area of Northeast British Columbia.
The most recent well, a-49-J/94-J-8, near Klua Lake 30 miles southeast of Fort Nelson, encountered 162 m of dolomitized reef in the Devonian Pine Point formation, including 57 m of net pay, said Search Energy Corp., Calgary. TD is 2,400 m.
The companies planned to complete a-49-J and drill c-18-J. Each well is on a separate structure.
Another well, d-27-J, blew out Dec. 6 and was capped Dec. 18, 1999, after drilling 14 m of reservoir. No injuries were reported. D-27-J flowed 15 MMcfd of gas in January on a 33/64 in. choke with 10% reservoir pressure drawdown.
Consulting engineers assigned 5.2 bcf of proved reserves and 2.9 bcf of probable additional reserves to Search's 50% working interest. Gas from d-27-J analyzed 0.5% hydrogen sulfide and 8% carbon dioxide.
Work was starting in early March on a flow line from d-27-J to the existing gathering system to Westcoast Energy Inc.'s Fort Nelson gas treatment plant.
UPR expects production to start around July 1 at about 25 MMcfd. Additional gathering and processing capacity will be needed to handle volumes above that. About 8 bcf of gas remains to be produced from five wells shut-in since 1997, Search said.
The companies planned to acquire 26 sections of 3D seismic data before spring breakup. Search acquired its interest in late 1998 and processed and interpreted 25 sq km of existing 3D seismic data.
Petro-Canada initially discovered and developed the field in 1989-91. By yearend 1990 it reported marketable reserves of 75 bcf from four successful wells (OGJ, Jan. 28, 1991, p. 46). Petro-Canada owns 19% of Search Energy.
