... with inherent uncertainties. Interestingly, the study sheds light on the multifaceted factors contributing to pipe sticking conditions, even when initially perceived as differential sticking. Notably, in wells with minor doglegs, secondary geometric factors such as borehole torsion emerge as significant...

... Abstract This paper presents a case study of the first installation of an on-demand activated Remote Actuated Shoe (RAS) in offshore extended-reach wells. The Middle East operator faced challenges related to potential differential sticking while running lower completions in high overbalance...

... marl and chalky limestone deposit below it was caving. Moreover, Khasib’s 80m thickness consists of marl and white limestone. However, the important pay zone area was 400m-thick limestone Mishrif formation, which can cause gas difficulties, mud losses, differential sticking, and small holes. Also...

... of this BHA takes approximately 5-7 minutes of stationary time, not inclusive of connection time, leading to higher stuck-pipe risk such as solids-induced pack-off and differential sticking. Therefore, an optimized mud weight is planned to support the borehole with its Nahr Umr (shale) and Shuaiba (Limestone...

... Abstract This paper will describe a successful application of Nano deformable sealing polymer to mitigate a high risk of differential sticking while drilling weak sand of Zeit formation with 17.2 ppg mud weight with overbalance up to 2,500 psi. While trying to combine Zeit and S.G formation...

... production. Pressure testing and reservoir fluid sampling operations require long stationary time and pose a risk of differential sticking. Deploying a pressure testing and fluid sampling tool into the drilling bottom-hole assembly (BHA) helps in maintaining well control through continuous circulation...

... during running hole of the liner, allowing greater lengths of wells for which liner can be deployed to TD. A field based analysis shows Lubricated brine to have friction factor reduction in range of 0.05- 0.08. Differential sticking concerns that were observed in some wells of this field have been...

... Abstract It is a challenge to drill a highly deviated or horizontal hole in high permeable formations. High differential pressures may lead to several problems like tight holes, wellbore instability, differential sticking and mud loss while drilling across these permeable or fractured...
