One of Canada's largest operators was looking for uphole gas potential in existing wells with depleted lower oil production. In one of their fields in the Bonnie Glen area they found gas potential in two Basal Quartz sands. The operator felt that the BQ sands were probably damaged during drilling and decided to use the PeneDRILL® technology as an alternative to conventional perforating and fracturing techniques because of the zone's close proximity to underlying water. A total of 13 tunnels were drilled over the two BQ sand sections and the well was tested. The well completed with PeneDRILL® flowed 84,000 m3/D (3.0 mmcf/D) gas from the Upper Section and 140,000 m3/D (5.0 mmcf/D) from the Lower Section. An offsetting well completed by perf and frac flowed 28,000 m3/D (1.0 mmcf/D) gas from the Upper Section and 56,000 m3/D (2.0 mmcf/D) from the Lower Section. The operator has since done several more PeneDRILL® jobs in this and other fields and is planning more. |

This water disposal well in the Granite Wash formation was suffering poor injection rates of 48 m3/D (maximum) at 9mPa pump pressure. The operator utilized the PeneDRILL® system to improve injectivity by making 8 penetrations over a 7 meter interval. A subsequent injection test achieved a rate of 400 m3/D at 5mPa and then the well was placed on injection at the desired rate of 190 m3/D at 4 mPa injection pressure.
