摘要： A process for upgrading a crude bentonite ore such that it can be used advantageously to prepare unusually high aqueous solution viscosities. This sequence comprises initially subjecting the crude ore to a working or shearing stage, followed by a drying step to about a 5 % moisture level. Na2CO3 is then dry-blended with the material, and the sequence is completed by subjecting the mix to a pulverizing step.

摘要： Aqueous-based insulating fluids that have greater stability at high temperatures with lower thermal conductivity may be used, for example, in applications requiring an insulating fluid such as pipeline and subterranean applications. For example, a method may include providing an aqueous-based insulating fluid in an annulus between a riser column and an outer casing disposed thereabout, the riser column connecting a wellbore penetrating a subterranean formation to a floating surface rig; and flowing a fluid through the riser column and the wellbore.

摘要： A method of servicing a wellbore within a subterranean formation comprising providing a drill string disposed within the wellbore having one or more tubulars associated therewith and forming one or more annuli around the drill string; placing an insulating packer fluid comprising an aqueous base fluid and a viscosifying agent into at least one of the one or more annuli surrounding the drill string; and performing a drill stem test while the insulating packer fluid is in place. A method of servicing a wellbore within a subterranean formation comprising placing an insulating packer fluid in an annular space between a tubular and a marine riser extending from a surface vessel or platform and a subsea wellhead, wherein the insulating packer fluid comprising an aqueous base fluid and a viscosifying agent and has a thermal conductivity of from about 0.008 BTU/(hr·ft·F) to about 0.245 BTU/(hr·ft·F).

摘要： A downhole fluid may be circulated within a wellbore where the downhole fluid may include at least a modified perlite and/or an aerogel. The amount of the modified perlite and/or aerogel within the downhole fluid may range from about 5 vol % to about 30 vol% of the downhole fluid of the total amount of the downhole fluid. The downhole fluid may be a drilling fluid, completion fluid, lost circulation pill, displacement pill, and combinations thereof. The material may help the downhole fluid maintain a relatively low density of less than about 1100 kg/m

摘要： A fluid pressure transmission pill (FPTP) having an ultra-high viscosity for use in association with hydrocarbon drilling and exploration operations, particularly, managed pressure drilling (MPD) operations, is described. The ultra-high viscosity pill is a weighted pill composition that includes a hydrocarbon fluid, a thixotropic viscosifying agent, one or more activators, an emulsifier/wetting agent, a fluid loss control additive, and a weighting material. In accordance with selected aspects of the described fluid pressure transmission pill, the ratio of the amount of the thixotropic viscosifying agent to the activator is a ratio of about 7:1, and the weighting material is a barium-containing solid-phase material. Also described are methods of use of such FPTP products in subterranean operations, such as well killing operations during managed pressure drilling.
