... adaptable characteristics. Since the creation of the first synthetic polymer, global plastic production has increased very rapidly, from 2 million tonnes in 1950 [1] to 368 million tonnes worldwide in 2019, of which 57,9 only in Europe [2]. While nobody can deny the positive contributions of plastics...

... material and, at the same time, help the industry to reach the new target set by the European regulators for the recycling of plastic packaging. Currently, plastic waste composed by one type of polymer can be recycled through mechanical recycling. With the mechanical recycling process, plastics cannot...

... ABSTRACT Low Salinity water and Polymer injection are as two well known Enhanced Oil Recovery (EOR) technologies. The concept of Low Salinity Water (LSW) flooding has been documented as a promising water-based enhanced oil recovery method. In the same way, many experimental studies have been...

An experimental polymeric additive, with proper characteristics at subsea conditions, gave positive results leading to DR﹪ efficiency of about ~ 11﹪ that are, however, 5 time less than conventional polymeric DRA comparatively tested...

... was present. First step in both presented cases was to isolate the existing watered out layers by a water shut-off polymer. Once isolated, the new intervals identified were opened using the through tubing perforation technique using 1"11/16 gun. Afterwards when production history of the wells showed a sand...

Preliminary results obtained during the start-up and the current monitoring phase are showing good injectivity of polymer and a delayed breakthrough time, if compared to the results obtained during tracer campaign. The current prospective...

At present, xanthan gum is one of the two commonly water-soluble polymers used for polymer flooding, and makes a more excellent performance in salt resistance than that of hydrolyzed polyacrylamide (HPAM) in EOR. The objective of this study, was first to characterize the xanthan gum...

This paper will present a new polymer/monomer composite that is activated by thermally-dependant initiator for free-radical polymerization. The system boasts a rheology...

... ABSTRACT: As oil and gas reservoirs mature, water production increases. Several techniques are used for water shut-off and one of these techniques is the polymer flooding which is known to be cost effective. Saudi reservoirs are known for their high salinity and high temperature. In addition...
