Abstract: Water-based drilling fluids may include an aqueous base fluid and a mixture of polyethylene polyamines in an amount of from 1 lbm/bbl to 20 lbm/bbl relative to the total volume of the water-based drilling fluid. The polyethylene polyamines of the mixture may have a first chemical structure H2NCH2CH2(NHCH2CH2)xNH2, where x may be an integer greater than or equal to 3. The average molecular weight of the polyethylene polyamines in the water-based drilling fluid having the first chemical structure may be from 200 g/mol to 400 g/mol. Methods for drilling a subterranean well with the water-based drilling fluids are also disclosed.

Abstract: Lost circulation material (LCM) compositions for sealing lost circulation zones in wellbores may include an epoxy resin, a curing agent, an amide accelerator, and calcium carbonate having an average particle size of from 1,000 microns to 10,000 micron. The epoxy resin includes at least one of 2,3-epoxypropyl-o-tolyl ether, C12-C14 alkyl glycidyl ether, 1,6-hexanediol diglycidyl ether, butyl glycidyl ether, or cyclohexanedimethanol diglycidyl ether. The epoxy resin can also include bisphenol-A-epichlorohydrin epoxy resin. Methods of treating a lost circulation zone of a wellbore include injecting the LCM compositions into the lost circulation zone and curing the LCM compositions, where the LCM compositions include an epoxy resin, a curing agent, an amide accelerator, and calcium carbonate having an average particle size of from 1,000 microns to 10,000 microns.

Embodiments of a method for plugging and abandoning a wellbore may include introducing a sealing composition into a wellbore and curing the sealing composition to form a plug. The sealing composition may include from 1 weight percent to 20 weight percent of a curing agent, based on the total weight of the composition, and from 20 weight percent to 97 weight percent of an epoxy resin system, based on the total weight of the composition. The epoxy resin system may include an epoxy resin having the formula (OC2H3)—CH2—O—R1—O—CH2—(C2H3O), where R1 is a linear or branched hydrocarbyl having from 4 to 24 carbon atoms; and a reactive diluent having the formula R—O—CH2—(C2H3O), where R is a hydrocarbyl having from 12 to 14 carbon atoms.
