Well drilling and completion composition
Patent
·
OSTI ID:5965905
A water base well drilling and completion composition is described which, for each barrel of water base, consists of: (a) from about 0.10 lbs. to about 6.0 lbs. of a potassium salt of a copolymer of a two compounds wherein the first compound and the second compound are combined in a molar ratio of from about 1:1 to about 3:1 of the first compound to the second compound, and the copolymer has a weight average molecular weight of less than about 20,000; and (b) from about 0.10 quarts to about 10.0 quarts of an accelerator catalyst having water, from about 2 lbs. to about 80 lbs. of KOH per each bbl. of water, from about 10 lbs. to about 50 lbs. of lignite per each bbl. of water, at least 5 to 25 lbs. of K/sub 2/O per each bbl. of water; at least 5 to 15 lbs KCl per each bb. of water; and from about 1.0 lbs. to about 10 lbs. of sulfonated polystyrene per each bbl. of water and wherein the sulfonated polystyrene has an average molecular weight of from about 1 to about 12 million, and the accelerator catalyst having been prepared by heating the mixture of water, lignite, KOH and sulfonated polystyrene to a temperature of at least 120/sup 0/F while simultaneously stirring for at least 30 minutes.
