ABSTRACT:
A method of making a well fluid for use in a well which includes the steps of determining uphole and downhole operating temperatures in the well, and then contacting a well lubricant with a lubricating additive, wherein the lubricating additive has a cloud point temperature greater than the uphole operating temperature and less than the downhole operating temperature. A method of lubricating drilling equipment during opeation of a subterranean well, includes the steps of determining uphole and downhole operating temperatures in the well, and then contacting the drilling equipment with a treating fluid comprising a well lubricant and a lubricating additive, with the lubricating additive having a cloud point temperature greater than the uphole operating temperature and less than the downhole operating temperature.
