摘要： A flowline branch structure (10) has at least one inner branch assembly with an inner flowline branch and at least one inner flowline pipe attached to and communicating with the inner flowline branch. At least one outer branch assembly (12) of the flowline branch structure has an outer branch housing disposed around the inner flowline branch and at least one outer pipe (14) disposed around the inner flowline pipe and attached to the outer branch housing. A generally annular space is defined between the inner and outer branch assemblies. At least one wiring element including an electrical heating element is disposed in the sealed space on an outer side of the inner branch assembly. The, or each, wiring element extends in one continuous length across an interface between the inner flowline pipe and the inner flowline branch. This reduces the number of connections necessary to create the flowline branch structure.

摘要： A sensor system for the measurement of a physical parameter, such as temperature or pressure comprises a first, fixed module (5), and a second module (20) positionable proximate to the first. The first module has a measurement coil (6) and a reference coil (7), where the measurement coil forms part of an electrical circuit that is subject to variation by the physical parameter, and the reference coil forms part of a circuit not subject to the physical parameter being measured. The second module has a pair of reading coils (22, 23), each arranged to couple to respective measurement and reference coils, where the reading coils are connectable to signal generation and measurement equipment, and the system is arranged to measure electrical characteristics of the measurement and reference coils via the coupling. It has particular utility in harsh environments such as in wells, where the first module may be fixed, and the second module may be lowered adjacent the first. Measurements from the reference coil may be used to calibrate the measurements from the measurement coil. Further coils may be used to aid alignment of the two modules.

摘要： Downhole assemblies including a plurality of tubular members extendable within a wellbore and defining a through bore. A telemetry device is positioned within a wall of one of the plurality of tubular members and has a secondary flow path defined therethrough and a valve element engageable with a valve seat provided at an upper end of the secondary flow path. The secondary flow path extends between an inlet and an outlet, both of which fluidly communicate with the through bore and are defined in the one of the plurality of tubular members. A flow restrictor is located within the through bore and is axially positioned between the inlet and the outlet of the secondary flow path. The valve element is actuatable to control fluid flow through the secondary flow path to selectively generate a fluid pressure pulse.

摘要： A method for conveying an interventional tool downhole in a substantially self-piloting fashion. The method includes moving the tool in the well while using a communicative conveyance line coupled to a winch at the oilfield surface. Thus, real-time readings regarding downhole tool speed, line tension, etc. may be analyzed at surface and utilized to adjust the moving of the tool in an ongoing feedback loop. As a result, the adjustments are made based on true circumstances downhole as opposed to surface-based readings which may otherwise be less accurate. Therefore, efficiency of the operations may be maximized, operator time freed and the likelihood of catastrophic line based failures reduced.

摘要： Methods of designing a cementing operation for a cement body within a wellbore are described herein. One such method includes determining a stress for the cement body within the wellbore by simulating hydration of the cement body using cementing operation parameters and wellbore conditions. The hydration simulation includes calculating pore pressure for the cement body and accounting for changes in pore pressure associated with chemical shrinkage of the cement body. The method further includes designing a cementing operation using the stress for the cement body and the cementing operation parameters.

摘要： System and methods of modeling fluids in a simulation of fluid production in a multi-reservoir system with a common surface network are provided. Pressure-volume-temperature (PVT) data is determined for fluids in each of a plurality of reservoirs coupled to the common surface network. A shared equation of state (EOS) characterization representing each of the fluids across the plurality of reservoirs is generated based on the corresponding PVT data. Data representing properties of the fluids in each reservoir is calculated based on the shared EOS characterization of the fluids. When the calculated data is determined not to match the PVT data associated with the fluids in each reservoir, to the shared EOS characterization is adjusted based on a difference between the calculated data and the PVT data.
