Abstract:
A method includes drawing a fluid into a flow control assembly coupled to a completion string positioned within a wellbore, the flow control assembly including a first fluidic device and a second fluidic device, where the first and second fluidic devices exhibit different flow characteristics. A flow condition of the fluid circulating through the first and second fluidic devices is measured with a plurality of fluid sensors, and a water cut of the fluid is estimated based on the flow condition measured by the plurality of fluid sensors.
Abstract:
Provided is an expandable metal centralizer for use in a wellbore. The expandable metal centralizer, in one aspect, includes a downhole tubular positionable on a downhole conveyance in a wellbore. In accordance with this aspect, the expandable metal centralizer additionally includes one or more wellbore centralizing elements radially extending from the downhole tubular, wherein at least one of the downhole tubular or the one or more wellbore centralizing elements comprises a metal configured to expand in response to hydrolysis.
Abstract:
A shunt tube entry device comprises one or more inlet ports, a shroud disposed at least partially about a wellbore tubular, and a shunt tube in fluid communication with the chamber. The shroud defines a chamber between the shroud and the wellbore tubular, and the chamber is in fluid communication with the one or more entry ports.
Abstract:
A system for deploying an untethered dissolvable frac package for use in a hydraulic fracturing operation includes a dissolvable or degradable frac package with a dissolvable or degradable setting tool. The setting tool of the dissolvable frac package is configured to deploy a dissolvable frac plug at a predetermined position along the wellbore string and dissolve over time in the wellbore.
Abstract:
A magnetic system for determining a position of an untethered dissolvable frac package for use in a hydraulic fracturing or stimulation operation. The system includes an array of magnets operable to produce a magnetic field that is operably associated with a position downhole along the string. A setting tool of the dissolvable frac package is configured to sense the magnetic fields and deploy a dissolvable frac plug at a predetermined position along the wellbore string.
Abstract:
Method and system for deploying a frac package in a wellbore includes providing a location module for the frac package that can determine a position of the frac package in the wellbore. The location module operates to receive beacon signals from beacons located on the wellbore string and to calculate a velocity of the frac package based on the beacon signals. The location module further operates to calculate a location of the frac package based a time since a latest beacon signal and the velocity of the frac package. In some implementations, the beacons include at least one beacon that transmits or emits a signal and at least one beacon that does not transmit or emit a signal.
Abstract:
Acid stimulation operations in a wellbore may be conducted using frac plugs constructed of a hydrolytically degradable polymer. The frac plugs may be constructed of an aliphatic polyester such as PGA and may be readily pumped into position in the wellbore due in part to their relatively low density. Once perforations have been created in the wellbore and a first frac plug is set in place, an acid solution may be pumped at a high-pressure acid against the frac plug and into the geologic formation. A second and/or any number of subsequent frac plugs may be pumped behind the acid, e.g., in brine solution, to be used in subsequent acid stimulation operations. After completing acid stimulation operations, the frac plugs may degrade in the wellbore to permit production within two weeks.
