ABSTRACT:
The present invention relates to a method comprising the steps of introducing into a well borehole a composition, comprising water and an amount, sufficient to reduce drilling torque, prevent sticking or twisting of a pipe during drilling, or release a stuck pipe in a well borehole, of (A) at least one reaction product of (A-1) at least one hydrocarbyl-substituted carboxylic acylating agent and (A-2) at least one amine-terminated polyoxyalkylene having a number average molecular weight from about 600 to about 10,000, or at least one salt of the reaction product, and drilling the well borehole. Drilling torque, twisting and sticking of the pipe during drilling and releasing of stuck pipe in a well borehole are all effectively controlled by the methods and compositions of the present invention.
