RESPEC PROJECT

RESPEC is the prime subsurface science and engineering contractor to the Tu Deh-Kah geothermal project in British Columbia (tudehkah.com). We worked with Barkley Project Group to help the Fort Nelson First Nation secure the initial grant of $49 million from Natural Resources Canada to kick off this invocative geothermal power project in 2018. RESPEC began work in 2019 on the initial feasibility study by creating a geothermal-resource conceptual model; performing a preliminary analytical well-performance modelling and numerical reservoir simulation; and determining the plan for the reservoir characterization, well drilling, and testing.

Phase 3 of the project began in 2021. RESPEC participated in well targeting and design for a full-size production well and temporary injection well to characterize and test the reservoir. Both wells were successfully drilled and completed in 2021 under RESPEC’s recommendation and oversight. We designed a long-term, well-flow loop test and sampling program that was implemented in the fourth quarter of 2021 and an additional long-term flow test that was implemented in 2022. RESPEC is currently undertaking detailed reservoir simulation, well-test analysis, and final well design to support well targeting and design, surface facility design, and project financing.

Stages:
1. Preliminary Reconnaissance and Surface Exploration
2. Drilling Exploration
3. Feasibility Study
4. Well Drilling, Resource Production, and Power Plant and Transmission Line Construction
