Abstract
A cementing composition is flowed into an annulus between a tubular disposed within a wellbore formed in a subterranean formation and a wall of the wellbore. The cementing composition includes red mud, an epoxy resin, and a curing agent. The curing agent includes nitrogen. The curing agent crosslinks the epoxy resin to solidify the cementing composition, thereby cementing the tubular within the wellbore.
Claims19
A method comprising:
- flowing a cementing composition into an annulus between a tubular disposed within a wellbore formed in a subterranean formation and a wall of the wellbore, wherein the cementing composition comprises:
- red mud;
- an epoxy resin selected from the group consisting of 2,3-epoxypropyl-o-tolyl ether, C12-C14 alkyl glycidyl ether, or 1,6-hexanediol diglycidyl ether;
- and a curing agent selected from the group consisting of trimethyl hexamethylene diamine (TMD), diethylenetriamine (DETA), triethylenetetramine (TETA), meta-xylenediamine (MXDA), tetraethylenepentamine (TEPA), polyetheramine, isophoronediamine (IPDA), or beta-hydroxyalkyl amide (HAA);
- and
- crosslinking, by the curing agent, the epoxy resin to solidify the cementing composition in response to exposure to a downhole condition of the wellbore, thereby cementing the tubular within the wellbore.

A composition for cementing a wellbore, the composition comprising:
- red mud;
- an epoxy resin selected from the group consisting of 2,3-epoxypropyl-o-tolyl ether, C12-C14 alkyl glycidyl ether, or 1,6-hexanediol diglycidyl ether;
- and
- a curing agent configured to crosslink the epoxy resin to solidify the composition in response to exposure to a downhole condition of the wellbore, thereby cementing the wellbore, wherein the curing agent is selected from the group consisting of trimethyl hexamethylene diamine (TMD), diethylenetriamine (DETA), triethylenetetramine (TETA), meta-xylenediamine (MXDA), tetraethylenepentamine (TEPA), polyetheramine, isophoronediamine (IPDA), or beta-hydroxyalkyl amide (HAA).

- a tubular disposed within the wellbore;
- a cementing composition comprising:
- red mud;
- an epoxy resin selected from the group consisting of 2,3-epoxypropyl-o-tolyl ether, C12-C14 alkyl glycidyl ether, or 1,6-hexanediol diglycidyl ether;
- and
- a curing agent selected from the group consisting of trimethyl hexamethylene diamine (TMD), diethylenetriamine (DETA), triethylenetetramine (TETA), meta-xylenediamine (MXDA), tetraethylenepentamine (TEPA), polyetheramine, isophoronediamine (IPDA), or beta-hydroxyalkyl amide (HAA);
- and
- a pump configured to flow the cementing composition into an annulus between the tubular and a wall of the wellbore, wherein the curing agent is configured to crosslink the epoxy resin to solidify the cementing composition in response to exposure to a downhole condition of the wellbore, thereby cementing the tubular within the wellbore.
