The Tourmaline Oil Corporation's light oil play, referred to as The Field, utilizes electrical submersible pumps (ESPs) for the dewatering and initial production (IP) phase. Sucker rod pumps are then used as the main artificial lift technology to produce The Field. Typically, wells are converted to pump and rods after the first ESP failure or after the well ceases to flow naturally. Constant changes in the lift systems for each well incur costs, require manpower, and necessitate work on surface facilities.

The recent economic downturn has shifted focus towards reducing costs while optimizing production. A single wellhead that could accommodate flowing wells, ESPs, rod pumps, and gas lift without needing to change the flowline configuration would save money and minimize production downtime. To develop this technology, Tourmaline collaborated with industry leaders in wellhead penetration and rod pumping blowout preventers (BOPs) to design and engineer such a wellhead. This multi-function BOP can manage ESPs, rod pumps, natural flow, and gas lift. After the development of the multi-function BOP was complete, it was trialed in a controlled environment and then installed on multiple wells within The Field.

The product developed consists of a combination tubing hanger and production wellhead. This multi-function wellhead includes dual master valves, dual rod BOPs, ESP capillary feed-through, and gas lift capabilities with two flowline outlets. The final product is only thirty-one and a half inches in height, making it compact and operationally ergonomic. Efficiencies realized from this wellhead include modular wellhead skids, downhole artificial lift combination deployment, and reduced servicing costs. Surface conversion costs have been reduced by 95%.

Due to the unconventional well-flowing regimes and artificial lift practices Tourmaline Oil faces in The Field, the need for new technology was identified. By teaming up with industry leaders, an innovative and unique multi-function BOP wellhead was developed. The product has been installed throughout The Field with great success and has inspired other advancements in oil field efficiency.
