摘要： An object including a housing, a cone movably received in the housing, a piston body attached to the cone, a valve disposed as a part of the object and separating hydrostatic pressure from pressure at an interface between the housing and the piston body, and a trigger configured to open the valve at a selected circumstance. A method for moving a selected downhole tool including running an object into a borehole, counting features in the borehole using a sensor in the object, opening the valve at a selected count, flooding the interface with hydrostatic pressure, driving the piston body away from the housing, and moving a radially expandable shoulder member toward a larger diameter end of the cone. A borehole system including a borehole in a subsurface formation, a string disposed in the borehole, and an object disposed within or as a part of the string.

摘要： A frac dart including an electric counter in the frac dart, an inductor in the frac dart, in electrical communication with the counter, the inductor generating a voltage responsive to the dart moving through a magnetic field. A method for selectively landing a dart on a landing feature in a well including sensing a landing feature by generating an inductor signal with an inductor pursuant to the inductor passing through a magnetic field associated with the landing feature in the well. generating a count in an electrical counter of the dart responsive to the inductor signal, applying a count signal to a switch of the dart based upon the count, selectively passing the count signal to an activator or an actuator of the dart based upon switch position.

摘要： A screen connection area assembly configured to mount between adjacent sand screens of a gravel pack string including a body attachable to a screen connection area between two adjacent sand screens of the gravel pack string, the body configured to displace fluid and present a radial dimension between about 75% and 100% of a radial dimension of the adjacent sand screens. A method for packing a gravel pack string including disposing an assembly as in any prior embodiment on a screen connection area between adjacent sand screens of the string, running the string into a borehole, supplying a slurry to the borehole proximate the sand screens, packing the sand screens and the screen connection area between adjacent sand screens without altering a flow regime of the slurry.

摘要： Examples of techniques for enhanced reservoir modeling are disclosed. In one example implementation according to aspects of the present disclosure, a computer-implemented method includes estimating, by a processing device, a plurality of reservoir fluid values. The reservoir fluid values includes a density of the fluid, a velocity of the fluid, a pressure differential of the fluid, a temperature of the fluid, a viscosity, and an absolute pressure of the fluid. The method further includes modeling, by the processing device, a mass flow rate based at least in part on the plurality of reservoir fluid values. The method further includes applying the modeled mass flow rate to a wellbore operation.
