A method of sealing a formation that includes drilling a wellbore through the formation while pumping a non-aqueous based wellbore fluid comprising a first sealing component into the wellbore, wherein the non-aqueous based wellbore fluid filters into the formation as a filtrate and substantially thickens is disclosed. The substantially thickening may result from adding a second sealing component to the wellbore fluid, whereby the first sealing component initiates a reaction of the second sealing component.

Smart filtrate for strengthening formations

Wellbore fluids, and methods of use thereof, are disclosed. Wellbore fluids may include a non-oleaginous internal phase; an oleaginous external phase; at least one two-dimensional platelet-like material; a first latex-containing copolymer comprising at least one copolymer formed from at least one natural polymer and at least one latex monomer; and a second latex polymer distinct from the first latex polymer.

Self-crosslinking polymers and platelets for wellbore strengthening

A fluid loss control agent may include at least one thinner; and at least one polymeric component. A wellbore fluid may include a base fluid and a fluid loss control agent, which includes at least one thinner and at least one polymeric component. Methods of use are also described.

Wellbore fluids and methods of use thereof

Wellbore fluids, and methods of use thereof, are disclosed. Wellbore fluids may include a non-oleaginous internal phase, an oleaginous external phase, a first latex-containing copolymer comprising at least one copolymer formed from at least one natural polymer and at least one latex monomer, and a second latex polymer distinct from the first latex polymer.

Self-crosslinking polymers for wellbore strengthening

A method of sealing a formation that includes drilling a wellbore through the formation while pumping a non-aqueous based wellbore fluid comprising an encapsulated first component into the wellbore, the non-aqueous based wellbore fluid forming a filter cake on the walls of the wellbore; and adding a second component to the wellbore fluid when fluid losses are registered during drilling, whereby the first and second components react to form a chemical sealing layer in the filter cake is disclosed.

Smart filter cake for strengthening formations

Wellbore strengthening compositions and methods of use may include a base fluid and a plurality of hydrogel particles or a plurality of core-shell particles suspended in the base fluid. A method of treating a formation may include pumping a wellbore fluid into the formation, where the wellbore fluid includes a base fluid; and a plurality of hydrogel particles or a plurality of core-shell particles suspended in the base fluid.

Encapsulated polymers and selective activation thereof

The present invention relates to a liquid, self-breakable, temporary viscosifier agent (yield point enhancer) for oil based drilling muds, obtained by reacting one or more dicarboxylic fatty acids with a secondary dialkanolamine and thereafter with a tertiary tialkanolamine, and to oil based drilling muds containing it.
