Ab Initio molecular dynamics of the dissolution of oilfield pyrite scale using borax
(
Elsevier B.V.
, 2020 , Article)
Iron sulfide scales, particularly pyrite, form in oil and gas underground tubing and surface equipment thus blocking the flow of fluids and halting production. Therefore, the development of physicochemical processes for ...
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 ...
Rheology of Triamine Functionalized Silica Reinforced Polymeric Gels Developed for Conformance Control Applications
(
American Chemical Society
, 2020 , Article)
Recently, cross-linked polymers such as polyacrylamide (PAM)/polyethylenimine (PEI) have been used in conformance control applications to replace conventional lost circulation materials (LCMs). The objective of this work ...
Concurrent adsorption of cationic and anionic dyes from environmental water on amine functionalized carbon
(
IWA Publishing
, 2020 , Article)
Amine functionalized carbon (AFC) was synthesized from raw oil fly ash and later utilized it for simultaneous removal of methyl orange (MO) and rhodamine 6G (Rh6G) pollutant dyes from aqueous medium. AFC was analyzed through ...
Density-Functional Theory Investigation of Barite Scale Inhibition Using Phosphonate and Carboxyl-Based Inhibitors
(
American Chemical Society
, 2020 , Article)
Scale deposition is a critical issue in oil and gas exploration and production processes, causing significant blocking in tubing and consequently flow assurance and economic losses. Most studies addressing the scale formation ...
BET, FTIR, and RAMAN characterizations of activated carbon from waste oil fly ash
(
TUBITAK
, 2020 , Article)
Activated carbon (AC), a porous material with high pore volume, attracts increasing attention owing to
its potential applications in several fields. The development of a porous structure in AC marginally relies on both
the ...
Development of a New Borax-Based Formulation for the Removal of Pyrite Scales
(
American Chemical Society
, 2020 , Article)
In the oil and gas industry, pyrite forms one of the most hardened scales in reservoirs, which hinders the flow of fluids. Consequently, this leads to blockage of the downhole tubular, formation damage, and complete shutdown ...
Ab initio molecular dynamics investigation of CH4/CO2 adsorption on calcite: Improving the enhanced gas recovery process
(
American Chemical Society
, 2020 , Article)
Ab initio molecular dynamics simulations of CH4 and CO2 on the calcite (104) surface have been carried out for the molecular level analysis of CO2-enhanced gas recovery process (EGR). This process takes advantage of the ...
Reinforcement of polyacrylamide-co-tert-butyl acrylate base gel using nanosilica for conformance control at low and high reservoir temperatures
(
Society of Petroleum Engineers (SPE)
, 2020 , Conference Paper)
Challenges of water shut-off, which is categorized under conformance control, are nowadays common in the oil and gas industry. The excessive water quantities produced from oil reservoirs can make the production process ...
Influence of polyelectrolyte structure and type on the degree of flocculation and rheological behavior of industrial MBR sludge
(
Elsevier B.V.
, 2020 , Article)
The influence of polyelectrolyte's type and structure on the rheological characteristics of industrial highly stable membrane bioreactor (MBR) sludge have been investigated and were related to its degree of flocculation ...
