Abstract: A system and method for determining the asphaltene content of a downhole oil sample are provided. In one example, the method includes obtaining a hydrocarbon sample from a hydrocarbon formation of a reservoir at a given depth using a downhole tool. A liquid phase of the hydrocarbon sample is isolated within the downhole tool and the liquid phase is subjected to downhole analysis within the downhole tool to create a chromatography sample. The downhole analysis is based at least partially on size exclusion chromatography. A first property of the chromatography sample is measured to obtain a measured value, and a second property of the chromatography sample is estimated based on the measured value and known calibration curves.

Abstract: A method for estimating an elemental composition of a multiphase oilfield fluid includes obtaining a sample of a multiphase oilfield fluid; blending the sample with a viscosity modifying agent to transform the sample into a high viscosity paste; introducing the high viscosity paste into a chamber of an XRF apparatus; using the XRF apparatus to make an XRF measurement of the high viscosity paste; and evaluating the XRF measurement to estimate an elemental composition of the obtained multiphase oilfield fluid.

Abstract: Compositions comprise water, an acrylate monomer or a methacrylate monomer or a combination thereof, a free-radical polymerization initiator and a water-soluble bromide salt. Such compositions have utility in the context of remedial cementing, plug cementing in particular. The compositions may be pumped into a subterranean well, where they polymerize and form a support on which a cement plug may sit. The support may maintain the position of the cement plug in the wellbore and minimize cement-plug contamination.

Abstract: Methods for shortening the waiting-on-cement (WOC) time during primary and remedial cementing operations are disclosed. A fluid pill is injected into the wellbore that comprises reactants. The reaction is exothermic and heat is conducted into the cement sheath, thereby accelerating hydration and shortening the time necessary for the slurry to set and harden.
