In response to the oil industry’s demand for cost-effective well intervention methods, a novel inflatable packer anchor system has been developed to enable rigless installation of Insertable Progressing Cavity Pumps (I-PCPs), particularly in wells lacking Pump Seating Nipples (PSNs). Traditional I-PCP installations rely on PSNs or mechanical anchoring devices, both of which present limitations in terms of setting depth and axial load transmission, especially in extended-reach wells. The new system overcomes these challenges by utilizing hydraulic pressure alone for setting, eliminating the need for axial force. It integrates inflatable packer technology with a hydraulically actuated slip mechanism, featuring seal cups and a shearable intake sub to ensure tubing integrity and maximize flow-through capability. Retrieval is straightforward, requiring only an overpull to shear release pins, allowing the packers to deflate and slips to retract. The system’s first successful deployment occurred in South Oman’s Sadad field, where it was used to install an I-PCP in 3-1/2″ production tubing via rod string conveyance. The setting was achieved using a flush-by unit pump, and the well was immediately brought into production. This innovative technology not only simplifies I-PCP installation but also enhances operational efficiency, reduces costs, and expands the design flexibility of PCP/I-PCP completions. The paper discusses the technical aspects of the system, lessons learned from its initial application, and its potential to transform artificial lift strategies in the upstream oil and gas sector.
