Random Update Of A QEP In The Helis Grail -- EOG Isn't The Only Company With Huge Wells

Just for the fun of it, as I update some "old" wells. The well file for #25186 was for all three Bert wells (#25186, #25187, and #25188):

  • 25186, 2,170, QEP, Bert 1-2-11BH, Grail, t10/13; cum 103K 3/14; 21 miles southeast of Watford City; "the intended targeted reservoir is the Middle Bakken Sandstone and the Three Forks dolomite reservoirs of the Grail oil field." The Upper Bakken Shale (Devonian) was 23 - 25 feet thick; visibly saturated with oil, typical of petroliferous shales. The Middle Bakken (Devonian) the target formation for both the Bert 1-2-11BH and the Bert 2-2-11BH is a siltstone/sandstone unit in the Grail field...with oil stain....it took 11 days to drill the lateral for Bert 2-2-11BH and 17 days for the Bert 2-2-11TH .. the well file has the final cross section interpretations for the Bert 1-2-11BH, Bert 2-2-11BH 7 Bert 2-2-11TH. A generalized target zone was generated from the base of the upper packestone shoal to 23 feet below the upper Bakken Shale. This zone as maintained for an estimated 98% of the Bert 1-2-11BH and Bert 2-2-11BH laterals. The Three Forks target in the Bert 2-2-11TH was defined from 18 feet below the top of the Three forks to 33 feet below the top of the Three Forks at the top of the Massive Dolomite. The target zone was maintained for 90% of the lateral with a slight deviation below the target due to ineffective slides. Overall, all three lateral legs averaged 89.65 degrees down dip with minute variations due to the perpendicular  distance between the wells.
