Xanthan gum is a naturally occurring polysaccharide obtained from Xanthomonas
campestris. The xanthan gum backbone consists of β-d-glucose linked like in cellulose. The …

In oil and gas industry operations, scale deposition on the surface and subsurface
production equipment can cause different problems such as formation damage, loss in …

Chelating agents show very effective performance in different applications in the upstream
oil and gas industry. This study presents a critical review of the application of chelating …

The efficiency improvement of steam injection (more oil, less steam) is a critical challenge in
heavy oil recovery. Using chemical additives is one option to achieve this efficiency …

Tight sandstone reservoirs with low porosity and permeability are always vulnerable to
damage due to drilling and fracturing fluids, which significantly impedes hydrocarbon …

Chelating agents reduce the salinity of seawater (SW) and mimic low salinity water (LSW) by
binding metal ions in the solution and on the rock surface. This process decreases SW …

Drilling fluid circulation loss is referred to as “the most severe problem in drilling of oil and
gas wells”, as a routine solution, loss circulation materials are added to fill any fractures and …

Flow assurance is essential to a sustainable oil and gas production system; if not managed
appropriately, it may cause huge CapEx/OpEx and is also a life-threatening phenomenon …

Produced water re-injection (PWRI) is a promising and sustainable strategy to manage
substantial quantities of produced water for subsurface energy production systems. This …

This study used the diethylene triamine pentaacetic acid (DTPA)-seawater (SW) system to
modify the sandstone rock wettability and enhance oil recovery. The investigation involved …
