... due to solid content and/or scale, and characteristics of the reservoir itself. Pressure Transient Analysis (PTA) further validates significant skin and permeability reduction. To improve the injection rate, workover activities are conducted on the targeted well using a combination of the Acidizing...

... Abstract The evolution of horizontal drilling methodologies and subsequent completion strategies has successfully tackled numerous reservoir access hindrances. As the industry leans towards optimal operational expenditure and the augmentation of reserve extraction via amplified reservoir...

... This first-ever global deployment of the EIP took place in an injector well in the Supergiant field in the Mesopotamian basin of a Top Eastern country. The reservoir has high levels of lateral and vertical heterogeneity, a vuggy layer with an average thickness of 150 m, reservoir pressure close...

... Abstract Adaptive tension limits for the winch control system in automated wireline and slickline operations with backspool and slack controls are presented. The design addresses safety and access challenges for gravity conveyance that are exacerbated in complex reservoirs (deviated or tortuous...

... oil company which wanted to access a new and untapped section of a reservoir. This operation required passing through a 3.877" ID production tubing, featuring a landing nipple with a 3.562" ID, and drilling a new sidetrack from an existing deviated wellbore. Coiled Tubing Drilling (CTD) was the only...

... Oil-bearing productive intervals are stratigraphically divided into Balakhany and Fasila reservoirs. Pressure and log evaluation on this formation confirmed the complexity of fluid flow. Therefore, commingled production from both Fasila and Balakhany formations has been eliminated and dedicated...
