... Abstract The factors affecting sand production in weakly consolidated reservoir include formation characteristics, well completion and production parameters, etc. The flow space of oil and sand includes porous media, sand control media and production wellbore, which is continuous in space...

... and form a gel when the shear rate drops. The gel has high static gel strength and early compressive strength, which helps to seal the thief zones, prevent further losses, and prepares the wellbore for primary cementation. Advanced Lost Circulation System has a low density (~10 lb/gal), a low...

... drill bit and formation, impact and friction between drill string and wellbore, constraints exerted on drill string and drill bit, is proposed to simulate the distribution and variation of 3D displacement, velocity, acceleration as well as the stress state of entire drill string within specified time...

... Abstract For horizontal wells of the Changqing ultra-low-permeability oil reservoir stimulated via the multi-stage multi-cluster fracturing, an innovative production profile monitoring technology, adapted to the long horizontal wellbore and low liquid production, was developed to provide...

... Abstract Wellbore dynamics are essential in reservoir testing, acting as a vital connection between the reservoir and surface measurements. This study addresses the challenges in well control and emphasizes the advantages of utilizing wellbore dynamic simulation to enhance the safety...

... technology is the wellbore accessibility for surveillance, which can be overcome by installing the permanent Distributed Temperature Sensors (DTS) which can help in the production/injection flow profiling and help in optimizing the rates. To increase the life of the well, Rigless ESP will be required...

...-settable, and configurable packer's elements allowed precise injection of cleanout and WSO treatment in one run and worked on pump rates and accurate placement to operate under different configurations. This innovative approach eliminated the need for multiple plugs to isolate different wellbore sections...

... to support base production. Drainage produces rich carbonate formation water and high asphaltene oil which generates solid deposition inside the wellbore due to high temperature exposure as an impact of steam flooding. Solid deposition extracted into carbonate scale and congealed oil would lead to plugging...

... it was planned to carry out the test by placing the heater in a horizontal section with a drain hole and a slotted casing liner of 7 inch. The methodology behind using the Electrical Downhole Heater was to increase the temperature in and around the wellbore, which will not only reduce the viscosity of the crude...

... was adopted, allowing perforation in an underbalanced pressure regime. It is a standard practice in UAE to perforate the target reservoir zones in overbalanced condition, a condition in which the wellbore pressure is greater than the reservoir pressure, through wireline or pipe-conveyed gun before lowering...

... layers or cells in reservoir, which indicates risk of water or gas breakthrough will be distinct even in nearly part of reservoir. If the long horizontal wellbore was deployed in this kind of reservoir, when water or gas invade in wellbore even in very small part, the whole wellbore will be under...

... was run down the string in just 2.5 hours. 6 hours of shut-in temperature data was taken after completion; 8.5 hours of operating well temperature data was taken after normal production. Based on the fiber-optic logging DTS data, the reservoir-wellbore coupling model was established, and the model...

.... To expedite and enhance the process, the team leverages digital technology. The initial results of the acidizing job were highly promising, as the productivity of the wells showed significant recovery, confirming the successful removal of scale from the wellbore. Both the bullhead and coiled tubing unit (CTU...
