Abstract: A well logging instrument includes an instrument housing to traverse a wellbore penetrating subsurface formations. An electrically operated energy source that emits ionizing radiation is disposed inside the housing. An insulating sleeve is disposed between the energy source and an interior wall of the housing. The insulating sleeve comprises a thin dielectric film arranged in a plurality of tightly fitting layers of dielectric material disposed adjacent to each other and successively. A thickness of each layer and a number of layers is selected to provide a dielectric strength sufficient to electrically insulate the energy source from the housing and to provide a selected resistance to dielectric failure resulting from the ionizing radiation.

Abstract: A system for determining the phase envelope of a gas condensate includes a microfluidic device defining an entrance passageway, an exit passageway, and a microchannel in fluid communication with the passageways. The system includes an input sample bottle in fluid communication with the entrance passageway and a first pump associated with the input sample bottle for urging the gas condensate, in the input sample bottle, into the entrance passageway. The system further includes an output sample bottle in fluid communication with the exit passageway and a second pump associated with the output sample bottle for pressurizing the gas condensate, in the output sample bottle, into the exit passageway in opposition to the first pump. The system includes a temperature control device for controlling the temperature of the gas condensate in the microchannel. The first pump and the second pump operate to provide a desired pressure drop across the microchannel.

Abstract: Systems and methods are disclosed for interpreting measurements by a meter of defined dimension in a multiphase flow in a conduit in a wellbore. The meter may be a spinner used to obtain measurements at locations in the flow. The measurements may be averaged across a defined dimension, and a measurement model generated. A parameter profile (e.g., velocity) can be generated by curve fitting to the model.

Abstract: Methods and related apparatuses and mixtures are described for spectroscopic detection of hydrogen sulfide in a fluid, for example a formation fluid downhole. A reagent mixture is combined with the fluid. The reagent mixture includes metal ions for reacting with hydrogen sulfide forming a metal sulfide, and a capping agent that limits growth of the insoluble metal sulfide species by electrosteric or steric stabilization. The particle growth is one of chemical reaction or significant aggregation, and the capping agent further functionalizes the reagent mixture to exhibit properties outside the natural characteristics of the metal sulfide species to allow for spectroscopic detection of the metal sulfide species. The combined mixture and fluid is then spectroscopically interrogated to detect the presence of the metal sulfide thereby indicating the presence of hydrogen sulfide in the fluid. The mixture also includes chelating ligands for sustaining thermal endurance of the mixture under downhole conditions.

Abstract: A technique provides a system and methodology for detecting and monitoring erosion in various environments, including downhole environments. A tracer element is located in a component such that sufficient erosion of the component due to fluid flow exposes the tracer element. A monitoring system is disposed for cooperation with the tracer element such that exposure of the tracer element is detected by the monitoring system. The monitoring system outputs appropriate data indicative of the erosion to enable adjustments to the fluid flow.

Abstract: Systems and methods for estimating standoff and/or caliper in a wellbore for oil-based mud drilling are provided. The systems include a sensor having a primary electrode and at least two secondary electrodes, and an electronics subsystem having a controller and a processor for driving the system and correlating current measurements with standoff and/or caliper. The electrodes are positioned relative to one another such that there is a distinct flow of current between the primary electrode and each secondary electrode. In operation, a single excitation frequency is applied to the primary electrode and a simultaneous measurement of current flowing between the primary electrode and each secondary electrode is obtained. Standoff is estimated from the measurements. The estimations can be independent of formation properties when an appropriate excitation frequency is used.
