Drilling the wells presented significant technical challenges. After reaching a vertical depth of approximately 7,000 feet, the wells had to be turned 90 degrees to drill the horizontal sections. Russell Bentley, WSP’s project manager, observed: “The work was also being performed within a very restricted natural gas zone that was, in effect, only about two feet thick.” A geosteering technique involving the use of logging-while-drilling tools at the bottom of the drill string allowed the team to receive real-time data about the formation during the project.
The work was performed on a highly accelerated schedule, with two drilling rigs operating continuously for about four months to complete all five wells, while simultaneously adhering to rigorous safety requirements. Our expertise in reservoir and aquifer storage was instrumental in delivering this challenging project successfully.
