This paper evaluates and analyzes three decades of ongoing SAGD projects in Canada,
examining their successes, failures, lessons learned, and limitations from multiple …

In the oil and gas business, aminopolycarboxylic acid chelating compounds are commonly
employed to treat and regulate unwanted metal cations. The relationship between molecular …

Matrix acidizing in sandstone reservoirs require a series of chemicals to dissolve the
plugging materials around the wellbore. The selection of suitable chemicals is important …

Matrix stimulation of carbonates is an effective technique for improving production from both
damaged and undamaged wells. Production increases from these treatments are routine …

In this paper, contact angles in a rock/heavy-oil/steam system were measured to observe the
degree of wettability alteration when unconventional chemicals were added to steam. A …

The majority of gas reservoirs in conventional fields exist in carbonate reservoirs, and the
largest gas reservoir in the world is located in a carbonate formation. Actual rock samples …

The acidizing of sour, heavy‐oil, weakly consolidated sandstone formations under steam
injection is challenging because of fines migration, sand production, inorganic‐scale …

Acid fracturing is one technique for increasing carbonate formation productivity. The
injection of acid causes dissolution along the fracture, which results in conductivity. The …

Abstract Iron sulfide is a $1.4 billion/year problem in the oil and gas industry receiving little
R&D attention. The low success rate of organic acids and polyaminocarboxylic acids (PACA) …

Sandstone acidizing is the process of removing the damage from sandstone reservoirs to
restore the well productivity/injectivity to its original or expected rates. It differs from …
