Abstract
An aqueous based drilling fluid that exhibits improved lubricity, containing a sodium alkylglucosides hydroxypropyl phosphates lubricant component.
Claims18
Aqueous-based drilling fluids, comprising:
- an aqueous base fluid;
- a weighting agent;
- and
- a sodium alkylglucosides hydroxypropyl phosphate compound of the following formula:
- wherein:
- R is an alkyl chain having 8 to 22 carbon atoms;
- R1, R2, R3, R4 R5, R6, R7, R8, R9, R10, and R11 are consisting of:
- and H, with the proviso that R1-R11 are not all H;
- R12 is selected from the group consisting of:
- —O—P(O)—(OM)2 [mono phosphate],
- where M is a charge balancing group selected from H, Na, K, or NH4+
- and wherein when in formulation the counterions present in the sodium alkylglucosides hydroxypropyl phosphates may exchange with counterions of other ingredients;
- and
- wherein APG is alkyl polyglucoside defined in a) and b) above;
- and positional isomers thereof.
