application of a biomimetic wellbore stabilizer with strong

Application of a biomimetic wellbore stabilizer with strong

In this work, we developed TA-PVA as a subsea wellbore stabilizer for application in water-based drilling fluids, and mechanical measurements and mechanism analysis were the main goals of this study. The strong multiple hydrogen bonding of TA and PVA can produce a TA-PVA complex with excellent adhesion properties that can be adsorbed to various

Application of a biomimetic wellbore stabilizer with strong

Instability or possibly collapse of the wellbore might happen when the drilling fluid penetrates the NGH reservoir due to the NGH will decompose under the change of temperature and pressure. Therefore, TA-PVA complex as a biomimetic wellbore stabilizer with strong adsorption for WBDFs was developed to stabilize the NGH reservoirs.

An innovative method for studying the dynamic failure

A stabilizer is a finned sub placed within the BHA at designed location to centralize the drillstring inside the wellbore, to increase the load carrying capacity and to change the lateral side force on bit for controlling well trajectories in deviated wells (Ghasemloonia et al., 2015; Li et al., 2020).

a novel technique for the modeling of shale swelling behavior

A novel technique for the modeling of shale swelling behavior

One of the most significant problems in oil and gas sector is the swelling of shale when it comes in contact with water. The migration of hydrogen ions (H+) from the water-based drilling fluid into the platelets of shale formation causes it to swell, which eventually increases the size of the shale sample and makes it structure weak. This contact results in the wellbore instability problem

A Review of Past, Present, and Future Technologies

Leakage of oil & gas during fossil fuel exploration, production, and transportation poses a major environmental challenge that impacts the quality of air, water, soil, and ultimately the life on Earth. The result of uncontrolled spills & leakages may cause the contamination of groundwater as well as methane emission into the atmosphere increasing global warming, while the spills in open waters

Investigation of the Rheological Properties of Nanosilica

Wellbore strengthening has been introduced recently to resolve lost circulation problems by improving the fracture gradient and hence extending the mud window. Polymeric cross-linkable solutions showed outstanding strength with high thermal stability at elevated temperatures. In this study, silica with different sizes is used to reinforce the polymer solutions. The objective of this work is to
