A system and apparatus for providing an apparatus for use in a wellbore. The apparatus includes an apparatus body defining a volume, a propellant disposed within the volume, wherein the propellant has a first burn rate, and at least one propellant insert disposed within the propellant, wherein the propellant insert has a second burn rate, and the second burn rate is different than the first burn rate.

System and method for altering a burn rate of a propellant

A method for operation in wellbore includes contacting a downhole article comprising a cyanate ester composite with a treatment fluid comprising propylene carbonate at a temperature of about 25&#xb0; C. to about 300&#xb0; C.; and disintegrating the downhole article.

Methods of disintegrating downhole tools containing cyanate esters

A method of treating a subterranean formation penetrated by a wellbore comprises: introducing into the subterranean formation a treatment fluid comprising coated polymeric particles having a polymeric core and a curable thermoset coating disposed on the polymeric core; allowing the curable thermoset coating to cure under downhole conditions; and forming a fluid-permeable pack from the coated polymeric particles, the fluid-permeable pack reducing or substantially preventing the passage of formation particles from the subterranean formation into the wellbore while allowing passage of formation fluids from the subterranean formation into the wellbore.

Methods of controlling fines migration in a well

A pressure compensation system for enclosed spaces at a subterranean location changes volume with thermally induced solubility changes of a salt in water. The salt is held in an enclosure that is either rigid, or impervious and flexible or porous and flexible. As well conditions change and temperature increases, some of the salt goes into solution with a resulting decrease in volume that compensates for thermally induced volume increase due to temperature increase in the borehole. Conversely, a decrease in borehole temperature brings some of the salt out of solution for a volume increase to offset the volume decrease of the adjacent fluid to keep the pressure stabilized in the enclosed volume. In the porous enclosure embodiment the openings are sufficiently small to retain the salt even in solution. However, minimal net flows are anticipated for pressure compensation due to changing thermal effects.
