Abstract Increasing complexities of the trajectory design for oil well drilling, brings additional challenges of the wellbore integrity and stability, increasing the probability of stuck pipe. This paper presents case studies of a similar well where complex wellbore trajectory limited the wellbore access for conventional E-line operations, thus, advanced technique to recover and restore stuck drill string utilizing E-Coiled tubing was employed, minimizing downtime and eliminating expenses of workover or fishing operation. The case study explores the utilization of E-line coiled tubing with high grade explosive tool in two wells having complex trajectory with an inclination angle of up to 65 degrees. Initially, wireline was employed to achieve accessibility and to locate free point, but due to high deviation, it got restricted to shallow depth. Moreover, multiple challenges were linked with subject wells, including no circulation, annulus packoff, settling of mud solids and low minimum clearance in drill string. Considering mentioned challenges E-line coiled tubing was deployed, performing multiple successful runs with colloidal tool and recovering drill string in both wells. The employment of E-line coiled tubing with a colloidal tool proved to be successful for the recovery of stuck drill string. Both cases presented significant challenges and uncertainties, such as undefined free points and settling of solid particles in drilling mud with annulus packoff in one of the wells. Moreover, failure of NRV in the BHA elevated challenges for the E-line operation. Multiple control measures were taken for successful intervention operation including circulation of fresh fluid to overcome gel strength of the static mud and reduce drag forces, execution of the operation with heavy weight fluid to ensure well control and barrier envelop thus requiring high pressure exposure of the system with abrasive fluids, utilizing the larger explosive size to ensure fire-and-forget to release the string. Getting over the challenges with appropriate solutions resulted in the recovery of wells, avoiding expensive fishing operations, and reducing rig operations downtime. Utilization of coiled tubing with e-line addressed the challenges encountered during drilling of highly deviated wells. This successful application of coiled tubing opens the potential for performing advanced e-line operations in complex well trajectories.
