Effect of Fluid Viscosity and Fiber Length on the Performance of Fibrous Fluid in Horizontal Well Cleanout
(
Society of Petroleum Engineers (SPE)
, 2023 , Article)
During drilling, completion, and intervention operations, solids can deposit in the wellbore. Innovative cleanout fluids reduce the problems associated with inadequate hole cleaning. Various methods have been developed to ...
Machine Learning for Capillary Pressure Estimation
(
Society of Petroleum Engineers (SPE)
, 2022 , Article)
Capillary pressure plays an essential role in controlling multiphase flow in porous media and is often difficult to be estimated at subsurface conditions. The Leverett capillary pressure function J provides a convenient ...
Molecular simulations in upstream applications
(
Elsevier
, 2023 , Book chapter)
The development of powerful computers and molecular simulation has allowed researchers to use them to get useful information about electronic properties related to chemical and physical interactions at the molecular level. ...
Rheology of upstream complex fluids
(
Elsevier
, 2023 , Book chapter)
Rheology is an important characterizing technique as it affects all types of fluids. While oil and gas recovery is an operation that depends mainly on the interaction between different fluids, it is therefore important to ...
Phosphonated Lower-Molecular-Weight Polyethyleneimines as Oilfield Scale Inhibitors: An Experimental and Theoretical Study
(
American Chemical Society
, 2022 , Article)
For many years, amino methylenephosphonate (-CH2-N-PO3H2)-based scale inhibitors (SIs) have been deployed for preventing various scales in the oil and gas industry, particularly for squeeze treatment applications. However, ...
Effects of Pipe Rotation on the Performance of Fibrous Fluids in Horizontal Well Cleanout
(
Society of Petroleum Engineers (SPE)
, 2022 , Conference Paper)
The deposition of rock cuttings is a problem commonly faced during drilling, completion, and intervention operations. Using polymer-based fluids is a common technique to improve horizontal downhole cleaning. However, these ...
Rapid Curing Environmentally Degradable Polymeric Pill for Loss Circulation Treatment
(
Society of Petroleum Engineers (SPE)
, 2022 , Conference Paper)
Loss circulation is frequent while drilling in naturally fractured or depleted reservoirs, which is usually associated with high non-productive time (NPT). Moreover, naturally pre-existing fractures may propagate when fluid ...
A sustainable approach to synthesize phosphonated chitosan using ball milling and its application for oilfield scale management
(
Royal Society of Chemistry
, 2022 , Article)
For many years, the oil and gas industry has strived to develop environmentally friendly organophosphorus-based scale inhibitors. The natural polymer chitosan has recently gained significant importance for various upstream ...
Synthesis and performance evaluation of poly (acrylamide-co-malonic acid) as FeS scale inhibitor: experimental and theoretical investigations
(
Institute for Ionics
, 2023 , Article)
This article reports on poly (acrylamide-co-malonic acid) and poly(AM-co-MAc) copolymers that inhibit the iron sulfide scale. The iron sulfide scale is considered as one of the most challenging oilfield scales to dissolve ...
Hydrogen storage in gas reservoirs: A molecular modeling and experimental investigation
(
Elsevier
, 2023 , Article)
Hydrogen is one of the clean energy sources that can be used instead of fossil fuel sources to reduce greenhouse emissions. However, hydrogen supply intermittency significantly reduces the deployment and reliability of ...
