摘要： A method for contacting people involves identifying, prior to an exploration and production (E&P) tool session, a first person accessing a first portion of the historic information in a subterranean formation field data set, adding, prior to the E&P tool session, the first person to a people-in-context list by at least storing an identifier of the first person with a reference to the first portion of the historic information, presenting, during the E&P tool session to a user controlling the E&P tool session, a selection menu based on the people-in-context list, receiving, during the E&P tool session, a first selection from the user, wherein the first selection identifies the first person from the selection menu, and establishing, in response to the first selection from the user, a first communication session between the user and the first person in the people-in-context list.

摘要： 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.

摘要： A method for drilling a borehole includes obtaining, while drilling the borehole, sensor data for the drilling assembly, analyzing, while drilling the borehole, the sensor data using a drilling behavior model to obtain results, and adjusting the drilling of the borehole based on the results. The drilling behavior model models drilling of the borehole using a distance drilled, a number of touch points, a number of bend angles, a number of external moments, a number of lengths of distributed weights, a lateral displacement of a center of the borehole at a bit, at least one vertical displacement from the center of the borehole, at least one angular offset, at least one force, and at least one mass per unit length.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： The application discloses a method of treating a subterranean formation of a well bore, including providing a first treatment fluid substantially free of macroscopic particulates; pumping the first treatment fluid into the well bore at different pressure rates to determine the maximum matrix rate and the minimum frac rate; pumping the first treatment fluid above the minimum frac rate to initiate a fracture; providing a second treatment fluid comprising a second carrier fluid, a particulate blend including a first amount of particulates having a first average particle size between about 100 and 2000 µm and a second amount of particulates having a second average particle size between about three and twenty times smaller than the first average particle size, such that a packed volume fraction of the particulate blend exceeds 0.74; pumping the second treatment fluid below the minimum frac rate; and allowing the particulates to migrate into the fracture.

摘要： 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.
