Abstract: A method for evaluating a multiphase drilling fluid includes receiving a sample of the multiphase drilling fluid and modifying the sample to enhance a separation of a first NMR peak corresponding to a first fluid phase component and a second NMR peak corresponding to a second fluid phase component. A nuclear magnetic resonance (NMR) measurement is made of the modified sample and evaluated to compute a property of the drilling fluid.

Abstract: An electrical stability testing device includes a cup configured to receive a fluid sample. The testing device also includes a pair of electrodes positioned at least partially within the cup. The electrodes are spaced apart from one another by a predetermined gap. The electrodes are configured to have the fluid sample positioned within the predetermined gap while performing an ES test on the fluid sample in the cup. The testing device also includes a wiper positioned at least partially within the cup. The wiper is configured to pass between the electrodes after the ES test has concluded. A width of the wiper is greater than the predetermined gap between the electrodes. The wiper is configured to deform as the wiper passes through the predetermined gap such that the width becomes substantially equal to the predetermined gap and sides of the wiper contact ends of the electrodes to clean the electrodes.

Abstract: Systems, compositions, apparatus, and methods for hydraulically fracturing a subterranean formation traversed by a wellbore including mixing a gelling agent and water to form a base fluid, adding a gas and a proppant to the base fluid to form a foam fluid, alternating injecting into the formation the base fluid and the foam fluid, repeating the alternating injecting, forming regions of higher proppant concentration, and forming channels adjacent to the regions. Systems, compositions, apparatus, and methods for hydraulically fracturing a subterranean formation traversed by a wellbore including forming a base fluid with a gelling agent, forming a foam fluid with a gas and a proppant, injecting into the formation the base fluid, injecting into the formation the foam fluid, repeating the injecting the base fluid and foam fluid, and forming channels in the base fluid with faster flow than flow in the foam fluid.

Abstract: The disclosure pertains to methods for completing a well may comprise lowering a coiled-tubing in the well thus forming an annulus between the casing and the coiled-tubing, pumping down said annulus a treatment fluid above the fracturing pressure of the formation while also pumping fluid through the coiled tubing. The methods may also comprise monitoring in real-time the bottom hole pressure and increasing the pump rate through the coiled-tubing if an increase of bottom hole pressure is observed.

Abstract: A technique for pre-storing an application fluid in coiled tubing for use in a downhole application. The technique includes filling the coiled tubing with the application fluid in a manner that utilizes pressures substantially below that of the pressures utilized in the downhole application itself. The coiled tubing may then be charged to near the application pressure and placed in hydraulic communication with a well for the downhole application. Thus, the coiled tubing may serve as an application fluid storage device without the requirement of coiled tubing deployment or associated equipment and related costs.
