The present disclosure describes three-dimensional (3D) printing apparatuses, processes, software, and systems for producing high quality 3D objects. Described herein are printing apparatuses that facilitate control of energy beam characteristics using an optical mask during one or more printing operations.

Three-dimensional printing systems and methods of their use

Provided herein are methods, apparatuses, and non-transitory computer readable media concerning quality assurance of three-dimensional object(s) and their formation. In some embodiments, a plurality of variables is considered in assessing performance of a manufacturing mechanism (e.g., printer) utilized in forming the three-dimensional object(s). In some embodiments, a plurality of variables is considered in assessing a process for forming the three-dimensional object(s). In some embodiments, a plurality of variables is considered in assessing a quality of the formed three-dimensional object(s).

Quality assurance in formation of three-dimensional objects

A variable flow resistance system for use with a subterranean well includes a first flow path configured to receive a fluid, a sensor configured to measure a property of the fluid received into the first flow path, and an actuator configured to control an inflow rate of the fluid received into the first flow path based upon the property of the fluid measured by the sensor.

Variable flow resistance system for use with a subterranean well

The present disclosure provides three-dimensional (3D) printing processes, apparatuses, software, and systems for the production of at least one desired 3D object. The 3D printer system (e.g., comprising a processing chamber, build module, or an unpacking station) described herein may retain a desired (e.g., inert) atmosphere around the material bed and/or 3D object at multiple 3D printing stages. The 3D printer described herein comprises one or more build modules that may have a controller separate from the controller of the processing chamber. The 3D printer described herein comprises a platform that may be automatically constructed. The invention(s) described herein may allow the 3D printing process to occur for a long time without operator intervention and/or down time.

Three-dimensional printing and three-dimensional printers

Downhole tools comprising a body, wherein at least a portion of the body is degradable when exposed to a wellbore environment; and at least one oil-degradable sealing element composed of an oil-degradable elastomer, wherein the oil-degradable sealing element degrades in the wellbore environment. The oil-degradable elastomer is selected from the group consisting of an oil-degradable natural rubber, an oil-degradable synthetic rubber, and any combination thereof.

Downhole tools comprising oil-degradable sealing elements

Magnetorheological fluids may regulate fluid flow downhole by forming a fluid seal using a bridge plug apparatus. Bridge plug apparatuses employing a magnetorheological fluid may be deployed in a wellbore in a retrievable configuration or in a substantially permanent configuration. Retrievable bridge plug apparatuses may comprise spaced apart magnets having a gap defined therebetween, and a reservoir of magnetorheological fluid housed within the gap. The magnets move laterally with respect to one another to expand or contract the gap and to displace the reservoir of magnetorheological fluid radially with respect to the magnets. Other bridge plug apparatuses may comprise a flow path extending between a reservoir of magnetorheological fluid and the exterior of a housing, where at least a portion of the flow path is located within a gap defined between spaced apart magnets.

Bridge plug apparatuses containing a magnetorheological fluid and methods for use thereof

A flow control device can include water in a chamber, the chamber having a variable volume, a flow restricting member which displaces in response to a change in the chamber volume, and a biasing device which influences a pressure in the chamber. A method of controlling flow of steam in a well can include providing a flow control device which varies a resistance to flow in the well, the flow control device including a chamber having a variable volume, water disposed in the chamber, and a biasing device. The biasing device influences the chamber volume. Another flow control device can include water in a chamber, the chamber having a variable volume, a flow restricting member which displaces in response to a change in the chamber volume, and a biasing device which reduces a boiling point of the water in the chamber.

Flow control device for controlling flow based on fluid phase

A variable flow resistance system for use with a subterranean well includes a first flow path to receive a fluid, a flow rate sensor to measure a flow rate of the fluid received into the first flow path, and an actuator to control an inflow rate of the fluid received into the first flow path based upon the measured flow rate of the fluid.

Induced material segregation methods of manufacturing a polycrystalline diamond compact (PDC) cutter result in formation of a polycrystalline diamond/tungsten carbide (WC) composite material having a smooth compositional gradient from maximum WC concentration at one face to maximum diamond concentration at another face. Because the compositional gradient is smooth, very little or no mismatch of coefficient of thermal expansion occurs, which improves a service lifetime of the PDC cutter.

Systems and methods are disclosed for a well tool. The well tool system includes a receiving tool disposed in a wellbore tubular. The receiving tool is configured to transition from an inactive state to an active state in response to a triggering signal. The well tool system further includes a transmitting tool at a surface and proximate to the receiving tool. The transmitting tool is configured to wirelessly transmit the triggering signal to the receiving tool.

Wireless activation of wellbore tools

An assembly for creating a packer can include a downhole tool positionable within a wellbore. The downhole tool can include an outflow control device that includes a substantially circumferential slot, a port in the slot for receiving a sealant from a reservoir, and a flow restriction device that can be positioned between the substantially circumferential slot and an annulus of the wellbore. The flow restriction device can create a pressure difference between the substantially circumferential slot and the annulus of the wellbore.

Outflow control device for creating a packer

Systems and methods are disclosed for a well tool. The well tool system includes a receiving tool including two ends positioned in a wellbore tubular in a predetermined orientation. The receiving tool is configured to transition from an inactive state to an active state in response to a triggering signal.
