Abstract
In the gas and oil industry, efficiency optimization within unconventional reservoirs persists as a crucial and formidable challenge. As the exploration and development of these reservoirs advance, horizontal wells are being drilled to increasingly greater depths. Plug and perf (P&P), serving as the principal approach for reservoir stimulation, entails the execution of multiple stage hydraulic fracturing procedures subsequent to fracturing. A newly engineered dissolvable plug, which disintegrates following the main fracturing operation and thereby obviates the necessity for milling, substantially augments efficiency, curtails costs, and diminishes carbon emissions. Nevertheless, it typically requires 20 to 30 minutes and the pumping of 300 to 400 barrels of water to propel the ball downward and seal the plug inner bore to form isolation.
The modification of the wire line adapter kit (WLAK) to be commensurate with the dissolvable frac plug, along with the alteration of the ball drop method to ball in place (BIP), comprehensively resolves this predicament. It eradicates the ball chasing process for down hole isolation, truncates the operation time by 13% during the overall single stage stimulation, and conserves 300 to 400 barrels of water per stage. Through the assessment of the performance of the dissolvable plug in unconventional reservoirs, and in adherence to the PDCA model, the deployment process is streamlined, and the mechanical stability is fortified to preclude post plug and perf operations for the dissolvable plug, thereby diminishing non-productive time.
