DIAL Gas Lift Enables Production Optimization and Reduces Well Intervention in Southeast Asia Onshore Field

DIAL’s continuous pressure monitoring and surface controls offered the ideal components to safely and efficiently optimize the operator’s well performance.

Silverwell installed a DIAL unit equipped with six valves at 7,800ft MD enabling the Operator to maximize flexibility of the gas injection rate control. Pressure and temperature data from the in-well DIAL unit enabled downhole gas injection metering, which was verified against the gas injection surface flow meter throughout the pilot.

With a maximum available gas injection pressure of 1,500 psi on the surface, three gas lift stations were required to unload the well of completion fluid and reach the target gas injection depth. Reservoir and tubing pressure were sufficiently low, so gas injection could occur at the deepest possible point, just above the production packer. Conventional Injection Pressure Operated (IPO) valves and side pocket mandrels (SPM) were run above the DIAL units in station 1 and station 2 for well unloading.

The DIAL units were installed along with the Surface Control System (SCS), ¼” TEC and clamps. Silverwell also provided the services for Distributed Control System (DCS) integration. This allowed operators and production engineers to remotely monitor the well and control the DIAL System remotely, avoiding the need for wellsite visits.

To ensure the DIAL system met the installation KPIs, Periodic Flowing Gradient Surveys (FGS) were performed by the operator and verified the accuracy of the DIAL pressure and temperature sensing at depth.
