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.

摘要： An embodiment of a fluid control device includes a housing, a fluid channel defined within the housing, the fluid channel having a first surface and a second surface opposing the first surface and having an inlet, and a flow control body disposed in the fluid channel, the flow control body tapering toward the inlet. The body, in use, causing fluid flowing through the channel to diverge into at least a first path between the first surface and a first side of the body, and a second path defined by at least by the second side of the body. A geometry of the first path and the second path selected is based on a subcool of the fluid at a pressure of the fluid entering the fluid channel, and the geometry is selected to induce cavitation of the fluid to choke fluid flow through the fluid channel.

摘要： A downhole system includes a packer assembly including a backup ring. The backup ring includes a plurality of nested leaves nested sequentially in a circumferential direction with adjacent circumferentially positioned leaves to collectively form a substantially circular shape. Each leaf includes a receiving section and an insertion section, the receiving section receiving an insertion section of an adjacent leaf. Upon radial expansion of the backup ring, the plurality of nested leaves fan out in the circumferential direction.
