Abstract

See full text

A drilling fluid composition includes a latex including a first polymer and a second polymer. The first polymer includes polyvinyl alcohol and polyvinyl acetate. A molar concentration of the polyvinyl alcohol in the first polymer is greater than 80% and less than 100%. The second polymer has a general structure in which x is an overall molar ratio of styrene in the second polymer, y is an overall molar ratio of butadiene in the second polymer, and z is an overall molar ratio of carboxylic acid in the second polymer. A sum of x, y, and z is represented as s. Styrene (x) is in a range of from about 20% to about 30% of s. Butadiene (y) is in a range of from about 70% to about 80% of s. Carboxylic acid (z) is in a range of from about 1% to about 5% of s.
