This paper presents a case history in which a flawless 2.375-in CT intervention was performed to stimulate laterals with a proprietary multilateral entry bottom hole assembly (BHA) that steered the CT efficiently into the laterals. The injector well has a natural and un-natural lateral, both...

... Abstract The Valhall and Hod chalk fields have seen the rise of single-trip multistage fracturing (STMF) that allows stimulating two to four zones in a single day in contrast to the average of one zone every 2 to 3 days for conventional applications. Recent advancements focus on lowering...

Abstract An innovative coiled tubing (CT) real-time flow measurement tool was introduced in Ecuador to reformulate the stimulation workflow in water injectors, which comprised evaluation and treatment. This new technology enabled an integrated, single-run workflow instead: initial injectivity...

These acoustic tools helped to uncover the causes and explore possible solutions to failing plugs. This paper presents aggregate data encompassing casing wall loss at over 2700 plug locations and presents...

...Background The majority of the wells, producers and injectors, in the subject field are extended reach completed as openhole targeting carbonate reservoirs. Fig. 1 shows a typical producer completion where CT matrix stimulation is required to remove drilling-induced formation damage...

... Abstract Successful stimulation fluid placement in extended reach wells (ERW's) through coiled tubing (CT) is primarily dependent on the depth reached for maximum reservoir contact. Well configurations of minimum bypass (2.4 in.) and openhole sections (6 1/8 in.) are the main challenges for CT...
