DEEP Earth Energy Production Corp. (the “Corporation” or “DEEP”) is pleased to announce the results of the Border-5HZ horizontal well.  This is the deepest horizontal well in Saskatchewan’s history and the first 90° horizontal fluid production well in the world to be drilled and hydraulically stimulated for geothermal power generation purpose.

The open hole well was tested using a coil tubing nitrogen lift test, which indicated high permeability and flow capability with an absolute open flow capacity in the order of 20,000 cubic metres per day (m3/d) or a productivity index of 0.55 m3/day/kPa.  Successful mechanical stimulation and production modeling indicate a highly productive well – twice the productivity of an unstimulated well.  This well will sustain commercial production rates (100 litres/sec), while minimizing fluid drawdown.  Future production rates will be constrained by well design and pump capacity.

The horizontal well was spudded on September 11th and completed on October 24th using Horizon Rig #33.  The well was drilled to a total measured depth of 5,672 meters (3,450 total vertical depth) with a 2,000-metre horizontal section.  No significant issues were encountered during drilling and the geological, operations and Weatherford directional staff were able to maintain the well trajectory in the reservoir target zone for a significant portion of the lateral length.  This demonstrates the viability of horizontal drilling, supports the geophysical analysis, and further demonstrates reservoir continuity. The highest temperature measured during open hole logging was 127° Celsius (261° Fahrenheit).

The well was completed using a 20 stage NCS Multicycle stimulation sleeve system and cemented liner, and subsequently hydraulically stimulated with Element Technical Services as per standard horizontal well completions procedures.  Extended testing of the geothermal system will commence in late December/January using the Border-5HZ well producing from a 171-millimetre Halliburton/Summit electrical submersible pump (ESP) with produced fluids injected into Border-1 and Border-3 wells. This large volume production and injection loop test is required to refine the reservoir model and finalize the subsurface well design and spacing necessary for completing a Bankable Feasibility Study.  Well design details:

Tom Kishchuk has been appointed Chief Operating Officer effective November 25, 2020.  Tom joined the DEEP team in September 2020 as a special advisor to the management team.  Using his more than 30 years of technical and business management experience in the energy industry he will provide leadership to the surface operations and engineering teams as the project advances to achieve commercial operation of Canada’s first geothermal power plant.  Prior to DEEP, Tom was the President and Chief Executive Officer of Mitsubishi Hitachi Power Systems Canada, Ltd., and Vice-President Operational Support for Federated Co-operatives Limited.
