Abstract: A technique facilitates construction of a power cable, such as a downhole electrical power cable for use with electrically powered systems. Construction of the power cable is accomplished with an external layer which does not use metallic, wrapped cable armor.

Abstract: Provided is a tool-body that arranges ultrasonic and electrical capacitance sensors at close distances to the casing wall of the wellbore such that properties of thickness, flow velocity, acoustic impedance and the dielectric constant of the liquid layer are measured at a number of circumferential locations inside the casing of the wellbore. These measured values may then be combined to derive the average flow rate of the layer and also used to identify whether the liquid is water or condensate/oil, or a mixture of the two with a certain water-in-liquid ratio. Combined with a gas flow rate and a liquid droplets concentration measurement, the total liquid flow rate and liquid type can be derived.

Abstract: An instrument (and corresponding method) performs AFM techniques to characterize properties of a sample of reservoir rock. The AFM instrument is configured to have a probe with a tip realized from reservoir rock that corresponds to the reservoir rock of the sample. The AFM instrument is operated to derive and store data representing adhesion forces between the tip and the sample at one or more scan locations in the presence of a number of different fluids disposed between the tip and the sample. The AFM instrument is further configured to perform computational operations that process the data representing the adhesion forces for a given scan location in order to characterize at least one property of the rock sample at the given scan location. The properties can include total surface energy of the rock sample as well as wettability of the rock sample.
