A treatment fluid can include a base fluid and a lost-circulation package. The lost-circulation package can include plurality of particles of a first, second, and third lost-circulation material. The plurality of particles can be cellulose, sized calcium carbonate, and fibers. The particle size distribution of the plurality of particles can be selected such that the particles enter permeable areas of a subterranean formation to help prevent loss of the base fluid into the formation and allow most of the particles to pass through the screen of a shale shaker. The plurality of particles can have a particle size distribution of a d10 value in the range of 30 to 55 microns, a d50 value in the range of 60 to 100 microns, and a d90 value in the range of 130 to 190 microns. The treatment fluid can be used in an oil and gas operation.

Lost circulation material package with tailored particle size distribution

A solids-control fluid for controlling flow of solids in a subterranean formation is disclosed herein. The solids-control fluid can include a diluent and a curable resin. The diluent can include a mutual solvent and an ethylene glycol. The curable resin can be dispersed within the diluent for controlling flow of solids in the subterranean formation.

Diluent for solids-control fluid in a wellbore

A method of drilling a wellbore penetrating a subterranean formation, the method includes: during drilling operations, circulating in the wellbore a first aqueous drilling fluid composition including a modified starch and a calcium carbonate wherein the calcium carbonate has a first predetermined particle size; during the circulating, measuring one or more parameters to create a set of measured parameters; and during the circulating, responsive to one or more parameters of the set of measured parameters, changing the calcium carbonate with another calcium carbonate of a different particle size to obtain a second aqueous drilling fluid composition, wherein the first and second predetermined particle sizes are, independently, a dparticle size of about 1.0 &#x3bc;m to about 150 &#x3bc;m.

Changing calcium carbonate particle size with starch for reservoir fluids

Methods and compositions for using lubricants in subterranean formations, and specifically lubricants that comprise certain oils, surfactants and solvents, and methods for their use, are provided. In one embodiment, the methods include introducing a treatment fluid that includes a base fluid and a lubricant including at least one vegetable oil, at least one nonionic surfactant, and at least one cosolvent into at least a portion of a subterranean formation.
