In the early development of the Duvernay formation of northwestern and central Alberta, total well costs between $15 and 20 million were commonly reported by operators due to the much of the proven source rock of the formation requiring downhole completion equipment with pressure capabilities that exceed standard system pressure ratings of 69 MPa (10,000 psi).

Although drilling and completion costs have trended downwards, an operator using cemented liner plug-and-perf was interested in an alternate system to substantially reduce costs. The operator chose to run the Packers Plus StackFRAC® Titanium™ XV completion solution, which is specially engineered for multi-stage stimulation in wells where differential pressures can reach up to 15,000 psi (103 MPa) and extreme bottom hole temperatures can be encountered.

The system incorporated a monobore design using a Titanium XV SF Cementor™ stage collar. This stage collar eliminates the need for intermediate casing and reduces well construction costs. Designed to complement the StackFRAC system in HPHT environments, the Titanium XV SF Cementor is used to cement-back the vertical and build sections from the heel of the well and above the target formation.

“This cementing stage collar is hydraulically activated and designed to close without the use of a plug, reducing post-cement clean-out operations, debris and associated costs,” says Rob Oberhofer, Global Technical Advisor with Packers Plus.

The 20-stage system was run into a wellbore to a measured depth of 5,700 m (18,701 ft) with a lateral length of 2,014 m (6,608 ft). Approximately 26,900 m3 of fluid and 2,805 tonnes of proppant was pumped while completing the well. The entire stimulation operation was performed continuously and completed in less than 60 hours pumping time.

“We’ve also piloted the ball drop completion technique on the second Ferrier well, which reduced our completion costs by approximately 30 per cent; we’re now looking into expanding this method to more of our operations in the Duvernay,” commented the operating company’s chief executive upon completion.

Packers Plus Titanium XV completion solutions are customizable, and systems can be designed according to well requirements these field-proven solutions have been successfully deployed in some of the most challenging downhole environments worldwide, including offshore and geothermal wells.
