More Information
Summary:Lost circulation material (LCM) compositions may include a resin; an emulsifier selected from the group consisting of ethoxylated phenol, sodium salt of modified tall oil fatty amide, carboxylic acid terminated fatty polyamide, modified amidoamine, tall oil fatty acid, oxidized tall oil fatty amidoamine, ether carboxylic acid, and combinations thereof; a crosslinker, a cementitious and/or weighting agent; a retarder; a dispersant; and a silicon-based defoamer. The LCM compositions may have a thickening time of from about 3 hours than about 6 hours by reaching a Bearden consistency of 100 Bc. Methods of eliminating or reducing lost circulation in a lost circulation zone from a well may include introducing these LCM compositions into the well.
