... after the wellbore has been de-watered with a diesel pre-flush. The chemical reaction which is driven by heat and water results in a chemical bond between sand grains as shown in Figure 1 ( Shevelev et al., 2022 ). The treatment is displaced into the reservoir to achieve optimum penetration...

... schedule was designed to overflush and left no proppant mass in wellbore, an unconventional practice in this type of reservoir which led to decrease in operational times by precluding wellbore clean-up procedures after frac. This paper presents the successful field application of pillar fracturing...

... To boost the recovery of production from existing wells, several key factors need to be integrated in a comprehensive approach. A thorough understanding of the reservoir and wellbore conditions is crucial for improving the performance of wells that are not producing optimally. These components...

The Open Hole Multistage Completions (OHMS) are emphasized in this paper to show their overall strength in connecting the reservoir to the wellbore. The efficiency of OHMS supersedes some other...

... mechanism that uses surface pressure to increase the sealing force on the packer elements. Generally, these packers consist of mandrel, elastomer elements, piston and shear pins. After the tools are installed in the wellbore, a ball is pumped until it reaches the toe of the wellbore and closes...

The screen jacket was also partially blocked by a sleeve to simulate the partial burial of the screen in the wellbore. The multiphase flow patterns in the annular space around the screen and inside the valve housing were...

RP testing indicates potential causes of production impediments generated after drilling by filtercake deposition...

... plugging with drilling fluid solids, wellbore fluids are typically displaced to low or no solids systems before sand screen lower completions are run in to wells. Displacing the entire wellbore volume to low solids fluids can add significant cost particularly in high pressure wells. An option can...

Abstract Petroleum wells producing water are likely to develop deposits of inorganic scales that may form near the wellbore and may plug perforations, coat casing, production tubulars, valves, deteriorate pump performance, and affect downhole completion equipment. Scales form and precipitate...
