The extra reach cast-iron bridge plug (ERCI) was selected to address wellbore restrictions and enable accurate placement at depth. The system was deployed using a hydraulic setting tool (HST) with the necessary crossovers. Controlled pressure application via coiled tubing allowed for successful setting of the plug despite challenging downhole conditions, including pre-existing well pressure and potential obstructions.

A jet pump system was deployed as a cost-effective alternative to conventional well testing methods.

To ensure high-quality data acquisition, the system was complemented with both memory gauges and wireless downhole gauges integrated into the bottom hole assembly. Memory gauges recorded high-resolution pressure and temperature data throughout the operation for post-job analysis, while wireless gauges transmitted real-time downhole data to surface, allowing continuous monitoring and immediate optimization of the test.

A retrievable inflatable bridge plug (RIBP), equipped with a hydraulic disconnect, was deployed on drill pipe to a depth of approximately 3,000 meters. The inflatable design enabled effective sealing in challenging well geometries, while the hydraulic disconnect allowed reliable release after setting. The RIBP was deployed with a bull nose to facilitate permanent isolation of the selected wellbore section prior to sidetrack operations.

Hydromechanical bridge plugs (HMBP) were utilized as a simple and cost-efficient alternative to conventional plug systems. The HMBP design enables reliable mechanical setting using applied weight and/or pressure, while also providing the option for release through a straight pull or right-hand rotation if required. This flexibility makes the system suitable for both temporary and permanent abandonment operations.

A 7" SAPSAN Liner Hanger System was deployed in a telescopic well configuration consisting of a 20" conductor, 13 3/8" casing, 9 5/8" casing, and a 7" liner. Both the 13 3/8" and 9 5/8" casing strings were designed for two-stage cementing using external casing packers (ECPs) and Stage Collars with the required accessories, ensuring zonal isolation and cement integrity across the well profile. The liner hanger system enabled efficient liner deployment and secure anchoring, supporting long-term well integrity and successful continuation of geothermal development operations.
