摘要： The present invention is related to a downhole device for hydrocarbon producing wells without conventional tubing (tubingless completion), which improves the hydrocarbon production (gas, oil and condensate), selectively controls produced solids (reservoir sand and hydraulic fracture proppant) and eliminates liquid loading. The device of the present invention is designed according to selected well and reservoir characteristics by an integral methodology which includes the stages: data collection and analysis of the well operating conditions, selection of candidate well, sampling and analysis of produced solids, simulation of production conditions, design and manufacture and installation.
The device of the present invention:
Is installed, through an operation with slick line unit or any other operational method, to any well depth, according to well mechanical characteristics and needs;
Has a filtering element at the lower end which selectively retains produced solids from 50 microns, avoiding their transport from bottomhole to surface with produced fluids in the well, causing pressure drops through filtering element and porous media, and protecting of abrasion all components of petroleum production system;
Improves well production conditions due to the system internal geometry, generates a suction and dispersion effect of accumulated liquid in bottomhole, reducing up to 70% of pressure requirement to transport free of heavy particles liquids, from bottomhole to surface and increasing hydrocarbon production up to 300%;
Takes advantage of expansion energy of reservoir gas to change the intermittent flow pattern into dispersed flow pattern, increases gas velocity at least to 6 m/s, optimizing the flow pattern from bottomhole to surface, and extending the productive life; and
Optimizes the remaining reservoir energy and pressure, reducing produced water up to 60%, avoiding the premature use of other technologies to promote hydrocarbon production.-

摘要： Methods for hydraulically fracturing a subterranean formation to improve the production rates and ultimate recovery by contacting unconsolidated resin-coated proppant particulates residing in a propped fracture with a reactive crosslinker in order to form a consolidated proppant pack are described. Additionally, methods for use in water injection wells to consolidate the resin-coated proppant particulates in a gravel packed or frac packed region of a wellbore are also described.

摘要： A device, system and method are provided for using a seal sub to isolate a well. The seal sub generally has a primary channel extending through the seal sub and seat positioned within the primary channel. As a ball setting tool passes through the seal sub and the seat, a ball connected to the setting tool with a shear pin contacts the seat and selectively connects to the seal sub. A predetermined force can be applied to the ball setting tool to break the shear pin, which leaves the seal ball in place, and the seal sub and the seal ball isolate the downhole pressures and contents from the uphole pressures and contents.

摘要： The disclosure provides a packing monitor, method, and gravel pack system for real-time monitoring of a particulate for improved gravel packing. Via the real-time monitoring, the quality of the gravel pack can be detected in real-time. Accordingly, a top-off procedure can be performed without additional tripping of the inner service tool string. Detecting when the gravel pack is approaching screen-out can also be determined in real-time. Detecting when screen-out is approaching allows the operator to prepare to stop pumping in case of miscalculations or early screen-out. In one example, the packing monitor includes: (1) a packing detector configured to, when stationary within the wellbore, obtain measurements indicating presence of a particulate in an annulus of the wellbore at different positions along a length of a screen; and (2) a packing controller configured to determine, based on the measurements, a status of the particulate in the annulus at the different positions.

摘要： A gravel pack system has a heel section and a toe section that is downhole from the heel section. The system also includes a conveyance having an interior passageway for fluid flow to the toe section, a closing sleeve that forms an annulus with the conveyance, a shunt having a first section that provides a fluid flow entrance into the shunt, a second section that extends to the heel section along the gravel pack system, and one or more nozzles along the second section that provides fluid flow out of the gravel pack system at the heel section, and a shroud having a first section that is coupled to the closing sleeve and a second section that is coupled to the shunt, where the shroud and the conveyance form a second annulus.

摘要： Systems and methods include a method for multi-segmented oil production. A multi-segmented well production model representing production at a multi-segmented oil production facility is calibrated. The model models production based on well rates and flowing bottom-hole pressure data at various choke settings for multiple flow conditions for each segment of the multi-segmented well. Real-time updates to the well rates and the flowing bottom-hole pressure data are received. Changes to triggers identifying thresholds for identifying production improvements are received. The model is re-calibrated based on the changes to the triggers and the real-time updates. An optimization algorithm is executed to determine new optimal inflow control valve (ICV) settings. Using the re-calibrated multi-segmented well production model, a determination is made whether the new optimal ICV settings improve production. If so, the optimal ICV settings are provided to a control panel for the multi-segmented oil production facility.

摘要： A gravel pack system includes a liner assembly and a deployment assembly. The liner assembly includes a sand control screen. The deployment assembly facilitates rotation of the liner assembly and circulation through the liner assembly while running the liner assembly into a wellbore using a work string. The deployment assembly includes a crossover tool that is operated to facilitate gravel packing without manipulation of the work string. The deployment assembly also includes a setting tool for setting a packer and/or a sand barrier at the top of the liner assembly.
