摘要:
The isolation of selected regions downhole may be achieved using methods that include emplacing a polymerizable material within a wellbore, wherein the polymerizable material contains a polymerizable component and a latent curing agent; initiating polymerization of the polymerizable material; and forming a seal within the wellbore. Permanent or semi-permanent downhole seals may also be prepared using methods that include emplacing a section of pipe having a surrounding membrane into an interval of a wellbore, wherein the surrounding membrane contains a polymerizable material, and deploying the membrane downhole to form a seal.

Certain embodiments described herein are directed to silane coupling agents that may be used, for example, to covalently couple a polymer to a filler. In some examples, devices that include the polymer-silane coupling agent-filler compositions are also described.
摘要:
Apparatus and methods for measuring confining pressure, axial strain and radial strain of zonal isolation materials are described. This information is useful for evaluating these materials and predicting seal performance and potential failures of these materials.
摘要:
Apparatus and method comprising a plurality of particles which are magnetically attracted to one another in response to exposure to a magnetic field, and which maintain attraction to one another after removal of the magnetic field, the attraction being disabled when the particles are demagnetized, whereby the particles operate to alter the rheological properties of a fluid in which the particles are mixed when the attraction is enabled or disabled is disclosed.
