Title:
LOW VISCOSITY SYNTHETIC CEMENT
Document Type and Number:
WIPO Patent Application WO/2013/148116
Kind Code:
A3
Abstract:
The present invention relates to a synthetic cement that comprises a low viscosity monofunctional monomer, a dicyclopentadienyl moiety having a pendant free radical reactive species, 1,3-butyleneglycol dimethacrylate, unsaturated styrenic block copolymer, and a peroxide curing agent. Additionally it may include weighting agents depending on the circumstances of the well, as is well known to those skilled in the art. Other additional components such as oil based mud, suspending agents, Portland cement, acrylates and methacrylates, retardant curing additives, and clays may optionally be incorporated into the synthetic cement. The synthetic cement is activated by heat, for example, and can be crafted to set within a certain time frame, for example in 4 hours, so that it pumpable for as long as need be, and then be set to seal the well in the manner desired.
