A insulating annular fluid for reducing convective currents in the annular region a wellbore is provided that includes an oleaginous fluid, a silica, and, in some embodiments, organoclay.

Insulating annular fluid

In one aspect, embodiments disclosed herein relate to an oil-based wellbore fluid. The oil-based wellbore fluid may include an oleaginous liquid and a surface-modified precipitated silica, wherein the surface-modified precipitated silica comprises a lipophilic coating. In another aspect, embodiments disclosed herein relate to a method of drilling or servicing a well. The method may include circulating a wellbore fluid, such as that described in the paragraph above, into a wellbore, and recovering at least a portion of the wellbore fluid from the wellbore.

Reservoir wellbore fluid

In one aspect, embodiments disclosed herein relate to a wellbore strengthening composition including at least one polymer capable of polymerizing through a free radical polymerization reaction from the group of epoxy acrylates, modified epoxy acrylates, epoxy precursors, modified epoxy vinyl esters, unsaturated polyesters, urethane (meth)acrylates, polyester acrylates, epoxy vinyl ester resins having the formula (I), wherein R and R-Rmay be CH&#x2014; or H and R-Rmay be H or Br, and polymer combinations thereof; and at least one initiator, wherein the resin is present in the amount from about 10 to about 90 weight percent. 

Wellbore strengthening composition

A composition that includes a product resulting from a condensation reaction of quebracho with at least one organophilic species that includes a reactive amine is disclosed.

Fluid loss additive for oil-based muds

A wellbore fluid that includes an oleaginous base fluid; and a silanated weighting agent is disclosed. In particular, the silanated weighting agents may be produced by reaction between an alkyl alkoxy silane and a weighting agent Methods of formulating such fluids and methods of drilling using such fluids are also disclosed.
