... Abstract The injected CO2 in geological storage layers has lower downhole temperature compared to the storage formation. This induces cooling effects in the formation rocks surrounding the injection wells and their perforations. The stability of the perforations is affected by the cooling...

... perforation intervals are already within gas zone by performing contact logging to evaluate the latest gas-oil contact. Selecting the appropriate gas supply route proved to be beneficial for gas injection wells operation and performance, as well as for the oil production. Injectivity data suggests...

... amount of migrating fines including Plagioclase, Feldspars, Illites and Kaolinites which makes shockwave pulsing the optimal stimulation method to rectify the issue. During the execution, the shockwave pulsing tool was run inside the well with wireline and placed immediately across the perforation...

... have been completed cased and perforated completed with active sand control consisting of gauge 6 wirewraped sand screens and 40/60 gravel. While early production wells are still producing solids-free, some of wells drilled in recent years show solids production in the form of fines with d10...

... depth. By employing a rapid drilling method, the Puncher creates multiple accurate and consistent holes in a single run. Another process and solution involved coiled tubing runs for wellbore cleanout and abrasive jet perforation for creating targeted perforations, with real-time monitoring to maintain...

... against the formation through perforations that had been meticulously washed to remove the original cement. The choice of Bismuth Alloy P&A barrier over conventional materials was motivated by the desire for a more efficient and compact solution. The Bismuth Alloy barrier, requiring only 6 feet...

... Abstract The limited-entry technology was a key technology in the multistage fracturing of shale oil and gas horizontal wells to help distribute fracture fluid among multiple perforation clusters evenly. However, perforations could be eroded and enlarged because of high-speed and continuous...

... assessment for CCS feasibility. Considering the temperature difference between the storage formation and the injection fluid, the cooling effects could lead to a reduction of almost 15% in fracture initiation pressure (FIP). Notably, the FIP for perforations aligned parallel to the azimuth of the maximum...

..., and objective layer depth of less than 5,000 ft. Several challenges were faced during the design and execution phases. First, the fracturing tortuosity and high near-wellbore friction pressures due to 90° perforation phasing, combined with the dual monobore architecture of the well, presented problems. Second...

... to accommodate power requirement of ESP to run up to 60 Hz frequency. Well Data and ESP Design Result for KS-XXX1 and KS-XXX2 are shown in Table 1 and Table 2 . In some cases, the upsize well candidate is also combined with additional perforation in order to improve oil/reduce watercut post ESP...

..., it was proposed to carry out the trial test with the Electrical Downhole Heater (EDH) in one of the horizontal wells and check the performance in the production rates in comparison with other wells without EDH. Since the maximum pressure loss observed in any heavy oil well is near the perforation, accordingly...

... Abstract A customized completion and perforation design was introduced and successfully applied in an onshore vertical well (carbonate reservoir) in Abu Dhabi, UAE. A new approach of running a 3-1/2" single zone completion string deployed with Tubing Conveyed Perforation (TCP) system...

... CSQ was carried out in existing intervals (3201-3203 m & 3204-3208 m). After WOC, Cement was cleared up to desire depth and desired intervals (3199-3201m & 3208-3211m) were perforated for polymer gelant injection. Injectivity test was carried out and no injectivity was found...

The well had two zones of open perforation and it was then suspended with a combination of inflatable cement retainer, cement and sand plugs, and another V0 hydraulic plug above it. The first operational scope was to prepare the wellbore...
