A tracer particle includes a silica core and a plurality of polymer-coated oligonucleotides disposed within the silica core, on a surface of the silica core, or a combination thereof. Each of the polymer-coated oligonucleotides comprise a polymer that at least partially surrounds an oligonucleotide.

Oligonucleotide-containing tracer particles for subterranean applications

In a composition including a plurality of coated diamond nanoparticles, each diamond nanoparticle may have at least one silane functional group covalently bonded to a surface thereof. A method of forming coated diamond nanoparticles may include functionalizing surfaces of diamond nanoparticles with at least one of a fluorine-containing compound and an oxidant; dispersing the functionalized diamond nanoparticles in a solvent comprising a silane functional group; and forming covalent bonds between the silane functional group and the diamond nanoparticles. A method of forming a diamond coating may include depositing the diamond nanoparticles over a substrate.

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.
