Paper presented at the SPE/ICoTA Well Intervention Conference and Exhibition, March 26–27, 2019
Paper Number: SPE-194239-MS
... improves operational safety, efficiency and reliability, whereas downhole measurements help to obtain maximum well productivity by providing real-time downhole wellbore pressure, transient dynamic underbalance and/or overbalance for perforation cleanup and/or well stimulation. The new perforating system...

... deployment in terms of reservoir productivity, risks, and operational performance. For this well TCP was not considered due to reservoir and operational risks and challenges. Compared to the conventional electric wireline conveyance this new perforating technology offers better efficiency with only two...

Paper presented at the SPE/ICoTA Coiled Tubing and Well Intervention Conference and Exhibition, March 27–28, 2018
Paper Number: SPE-189933-MS
... Abstract In North America, refracturing has been found to be effective in many instances for increasing the longevity of the well production and helping to drill and complete offset wells. Several instances suggest that refracturing by bull-heading is relatively ineffective because fluids and...

Paper Number: SPE-184785-MS
... Abstract An Angolan operator needed to perform a coiled tubing (CT) acid micro-wash stimulation on a subsea sand screen completion in order to improve production. The CT simulation showed that the coil would not reach the objective, which was the bottom screen, even with friction reducers...

... undeveloped fields or by lithology. Operators are also able to gain higher recovery from old fields where production has declined over time, making new opportunities for matching technology to economies of scale for such marginal projects. This paper outlines the recompletion of an old field using radial jet...

... improved, it was also short-lived. All the wells exhibited a gradual loss in productivity after the stimulation treatments. Furthermore, in horizontal wells, the problem was aggravated as there is not enough control of acid placement over long open hole carbonate intervals where permeability or damage...

Paper Number: SPE-74848-MS
... Abstract This paper describes the startup and application of coiled tubing- (CT-) conveyed fracturing for sand-control purposes in an oil field in Indonesia. Sand production becomes a major problem where well servicing is routinely performed to replace worn or stuck subsurface artificial...

Paper Number: SPE-74846-MS
... Abstract Sand production is a well-known and costly problem in shallow unconsolidated sands. For years slotted liners have been used to control sand in these types of reservoirs. However, over time sand, fines and other debris can clog slots or make their way into the liner itself, thus...
