Horizontal wells provide high drainage area within the reservoirs. Advancements in horizontal drilling technologies are utilized to develop unconventional resources such as shale gas and coal bed methane. However, wellbore ...

For efficient drilling operations, cuttings transport within the oil and gas wellbore is fundamental. Inadequate hole cleaning results in many problems including reduced rate of penetration, increased torque, bit wearing, ...

Loss circulation materials in the last two decades have witnessed a lot of developments and implementations. New technologies and materials are introduced to treat various types of loss zones. However, the success rate is ...

The problem of lost circulation is a direct consequence of the presence of fractures or high permeability. Lost circulation material (LCM) is used to treat the loss that occurs or proactively strengthen the wellbore of the ...

Loss circulation encountered in highly fractured formations, depleted reservoir, or HP/HT intervals is the root cause of many problems plaguing the oil and gas sector for many years. High pore pressure narrows the window ...

Loss circulation is one of the major concerns in drilling and well construction. The uncontrolled flow of fluids into formation while drilling or primary cementing lead to substantial non-productive time (NPT). The methods ...

Cuttings removal out of the wellbore represents a real barrier for successful drilling operations. The performance of hole cleaning is determined by several factors. The current article provides a theoretical study of the ...

The settling of drilling cuttings is important for the drilling and clean-out operations. The current article provides a Computational Fluid Dynamics (CFD) modeling study of particle settling behavior during the drilling ...

The traditional way to mitigate loss circulation in drilling operations is to use preventative and curative materials. However, it is difficult to quantify the amount of materials from every possible combination to produce ...
