Barite settling in the annulus behind the casing is an undesired yet common occurrence during the life of a well. Over time, the drilling fluid left in the annulus settles, leaving behind solidified barite that can hinder slot recovery and plug and abandonment (P&A) operations by impeding the cut and pull process. During a P&A operation, Equinor ac...

Settled barite is a known challenge in well construction and well control activities. This phenomenon creates operational and safety challenges during cut and put operations in well abandonment activities. In this paper, we introduce a novel approach to mitigate these challenges by dispersing settled barite particles using chelating agents, specifi...

Silica, a predominant metal oxide and fundamental component of the Earth’s crust, exerts significant influence on diverse geochemical and industrial processes through its interactions with water. This study delves into the surface modification of bentonite clay, as a naturally occurring aluminosilicate source, via treatment with varied concentratio...

The long‐distance pipeline transportation of heavy crudes demands optimal pumping procedures to abate overhead expenditures in the midstream phase. This can be facilitated by reducing both the oil viscosity and the frictional losses induced by the turbulent flow zone. The dualistic approach of reducing both viscosity and drag requires the optimizat...

Gas–liquid flow is a significant phenomenon in various engineering applications, such as in nuclear reactors, power plants, chemical industries, and petroleum industries. The prediction of the flow patterns is of great importance for designing and analyzing the operations of two-phase pipeline systems. The traditional numerical and empirical method...

Increasing the cuttings transport efficiency in deviated wells is difficult due to the rolling transport and cuttings settling on the low side of the annulus. Advancing flow rates and improving mud properties may not be applicable for proper hole cleaning because of the hydraulic and mechanical limitations. Under these situations, the major contrib...

In Bangladesh, Water based mud is used for drilling operations rather than oil based mud for a number of reasons like economic and environmental advantages. The mud used for drilling is managed from commercial company which causes a large amount of money. If the mud can be managed from nature which is likely commercial mud, it will result in consid...
