... of halite inhibitors are not well-known, and lack of information can lead to overtreating the scale with higher inhibitor concentrations than needed. By simulating the temperature drop that occurs when brine is transported from the downhole to the surface, this approach can establish the effective SI range...

... to determine the reaction rate constant at various temperatures. This information was used to determine the activation energy and pre-exponential constant. These important parameters were then used to model the degradation reaction using an Arrhenius equation to predict the material lifetime as a function...

...- or even nano-meter sizes, and since they are connected in space, detailed cement characterization requires advanced experimental techniques of good resolution that can provide three-dimensional (3D) information. In the present paper we demonstrate how the nano- and micro-structure in the interior of set...

... Abstract Understanding connectivity between injection and production wells is valuable information for reservoir management. Typically, connectivity might be evaluated using downhole pressure information or by injecting tracers into the reservoir. A less established but inexpensive technique...

The methods developed provide an understanding of the hydrolysis of PSs in fracturing fluids as well as quantitative information regarding degradation products. The general structure of most PS biopolymers used in hydraulic...

.... The DDFM approach has identified key production drivers for a gas-well field in Australia. This information has been useful to explain hydraulic fracture well production and provide guidelines for future fracture stimulation success. A DDFM process was used to develop a model for 32 wells completed...
