Investigation of the rheological properties of nanosilica-reinforced polyacrylamide/polyethyleneimine gels for wellbore strengthening at high reservoir temperatures
(
American Chemical Society
, 2019 , Article)
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 ...
Development of a polyacrylamide-based mud formulation for loss circulation treatments
(
American Society of Mechanical Engineers (ASME)
, 2021 , Article)
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 ...
A comprehensive rheological study for a flowing polymer-based drilling fluid used for wellbore strengthening
(
Society of Petroleum Engineers (SPE)
, 2020 , Conference Paper)
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 ...
Settling behavior of fine cuttings in fiber-containing polyanionic fluids for drilling and hole cleaning application
(
Elsevier B.V.
, 2021 , Article)
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, ...
Gelation kinetics of PAM/PEI based drilling mud for lost circulation applications
(
Elsevier B.V.
, 2021 , Article)
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 ...
Assessing the relation between mud components and rheology for loss circulation prevention using polymeric gels: A machine learning approach
(
MDPI AG
, 2021 , Article)
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 ...
CFD analysis of turbulent flow of power-law fluid in a partially blocked eccentric annulus
(
MDPI AG
, 2021 , Article)
This study focuses on analyzing the turbulent flow of drilling fluid in inclined wells using the Computational Fluid Dynamics (CFD) technique. The analysis is performed considering an annulus with a fixed eccentricity of ...
A CFD- RSM study of cuttings transport in non-Newtonian drilling fluids: Impact of operational parameters
(
Elsevier B.V.
, 2022 , Article)
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 ...
CFD modeling of particle settling in drilling fluids: Impact of fluid rheology and particle characteristics
(
Elsevier B.V.
, 2021 , Article)
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 ...
Loss circulation in drilling and well construction: The significance of applications of crosslinked polymers in wellbore strengthening: A review
(
Elsevier B.V.
, 2020 , Article Review)
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 ...
