A method may include: circulating a drilling fluid in a wellbore, wherein the drilling fluid includes: an aqueous phase; and a reclaimed carbon black additive; and drilling into a subterranean formation to extend the wellbore while the drilling fluid is circulated therein.

Reclaimed carbon black drilling fluid additive

De-oiled lost circulation materials and methods of using such materials to, for example, reduce fluid loss are provided. In some embodiments, such methods include introducing a first treatment fluid including a base fluid and a de-oiled plant material into a wellbore penetrating at least a portion of a subterranean formation including a loss zone; and allowing the de-oiled plant material to at least partially plug the loss zone.

De-oiled lost circulation materials

Methods for producing a swellable packer in a downhole environment are provided. A method includes introducing a treatment fluid containing a polymeric composition into a wellbore within the downhole environment and exposing the polymeric composition to an acid to produce a swollen polymeric material within the downhole environment. The polymeric composition contains a reaction product of at least one or more monomers, one or more comonomers, and one or more crosslinkers. The acid can be in situ formed from an acid precursor introduced into the downhole environment.
