Analysis of oilfield waters by ion chromatography to determine the composition of scale deposition

Progress on the relationship between miR-125 family and tumorigenesis

“…Scale precipitation could also cause various damages including blockage of pipeline and equipment, energy leak, accelerate corrosion, and severe accidents, which can influence the safety of production and the economic benefit of petroleum industry (El-Said et al 2009) and thus should be avoided completely in the oilfield industry. This paper reviewed and assessed some of the management and mitigation strategies of oilfield scale for oil and gas production.…”

A preliminary research on polyvinyl alcohol hydrogel: A slowly-released anti-corrosion and scale inhibitor

“…Therefore controlling the salinity of oilfield waters prior to water injection plays a crucial role in the exploration and production of petroleum (El-Said et al, 2009). To lower the salinity of injected water, "planned-water", a mixture of different kinds of water, has been used (El-Said et al, 2009;Shalabi et al, 2014).…”

Moreover, as the main concerns of scale and corrosion problems are iron compounds and calcium carbonate (Moghadasi et al, 2004;Martos et al, 2010;Jing et al, 2013), chemical control, such as adding poly-aspartic acid and acetic acid , is generally regarded as the most effective method, both in performance and cost (Lavania et al, 2011;Pillay and Lin, 2014).…”

Laboratory investigation of a new scale inhibitor for preventing calcium carbonate precipitation in oil reservoirs and production equipment

“…Next, CaCO 3 particles combine in microcrystals that serve as crystallization centers for the remainder of the solution. Crystal aggregates grow and precipitate or attach to the walls of the equipment at certain sizes (Tomson et al 2003;El-Said et al 2009;Kelland 2011). Calcium carbonate is found in the form of white crystals.…”
