The surface and upper intermediate sections were to be rotary drilled and the lower intermediate to be drilled with casing set below the Kalubik shale. The production section was planned to be rotary drilled to reach a prognosed depth of 11,433’ MD / 6,112’ TVD in the Kuparuk C sand. The following objectives were taken from the 2K-29 Drilling and Completions Program: Drill well safely with no injuries or environmental incidents. Drill a cost effective well that is within budget and schedule. Recover resources in the Kuparuk C sand to replace/increase production from the abandoned 2K-02 Utilize casing while drilling (CWD) to successfully drill bottom portion of intermediate hole and prove feasibility of the technology for future use at Kuparuk. The 13.5” surface and 8.5” upper intermediate sections were drilled prior to Canrig rig up. Mudlogging commenced during the drilling of the lower (CWD) 8.5” intermediate. TD for the 8.5” section was called at 8739’ MD / 6098’ TVD based on cuttings and a ROP break, as there was no LWD. The sand observed at TD did not appear to be the Kuparuk C as it lacked glauconite, was of smaller grain size, had no oil indicators, and there was no siderite cap, but at the time it was thought the C sand was not present and the well had encountered a lower sand member. A secondary reason for calling TD was based on casing fatigue parameters. Based on the lithology of the lateral section, it was determined this sand was actually a stringer within the lower Kalubik. The 6.125” lateral section was drilled to a total depth of 11013’ MD / 6096’ TVD. The top of the Kuparuk C sand was encountered at 8875’ MD / 6135’ TVD. The well was completed with a 4.5” perforated liner set at 11003’ MD / 6096’ TVD. 2K-29 6 2.3 Daily Activity Summary 4/26/2014: Canrig arrived on location and began rigging up during the drilling of the 7” section. 4/27/2014: Drill from 7734' to 7826'.

Siltstone varied from medium gray to grayish black and with a range of tenacities from soft to brittle to crumbly. Micro laminations of carbonaceous material were common within siltstones. Sand horizons consisted of unconsolidated upper very fine to upper fine grains. Siltstone graded into a grayish black silty shale towards the bottom of the interval. This zone did not contain any oil shows. Individual sample descriptions are as follows: Sand (7890' - 7940') = medium light gray with slight light olive gray secondary hues; upper very fine to lower fine; subangular to subrounded; well sorted; unconsolidated; texturally and compositionally sub mature; 70% translucent to frosted quartz, 30% black to grayish black lithic fragments; traces of feldspar and pyrite. Siltstone (7940' - 7995') = dark gray; moderately to well indurated; crumbly to brittle tenacity; earthy to hackly fracture; flaky to scaly to occasionally elongated cuttings habit; sucrosic texture; slightly metallic luster; thinly laminated; highly reactive to HCl; common black lithic fragments; scattered cuttings of white clay mineral.
