Abstract:
Disclosed herein are embodiments of systems, methods, and computer program products for assessing the data-quality of the calculated reservoir-rock resistivity R sd in laminar formations. For instance, in one embodiment, a computer-implemented method for assessing the data-quality of the calculated reservoir-rock resistivity R sd in laminar formations comprises the steps of receiving multi-component induction (MCI) data and other sensor logs data associated with a laminar formation; determining a set of calculated reservoir-rock resistivity R sd using at least one of the multi-component induction (MCI) data and other sensor logs data; and performing data quality assessments of the set of calculated reservoir-rock resistivity R sd .

The disclosed embodiments include a tubing deployment system. In one embodiment, the tubing deployment system includes a first tubing string having a first weightable collar. The tubing deployment system also includes a second tubing string having a second weightable collar. The first weightable collar and the second weightable collar each includes an interlocking locking member and a plurality of receivers spaced radially about an external surface of the respective weightable collar, where each of the plurality of receivers is configured to receive a weight.
Abstract:
The disclosed embodiments include a differential coupling system, a method of coupling a first mandrel to a second mandrel and a coupler. In one embodiment, the system includes a first mandrel having a first external thread about an external surface of the first mandrel. The system also includes a second mandrel having a second external thread about an external surface of the second mandrel. The system further includes a coupler that includes a first internal thread that complements the first external thread of the first mandrel and a second internal thread that complements the second external thread of the second mandrel. The system further includes an aligning pin configured to engage a first aligning hole of the first mandrel and a second aligning hole of the second mandrel to restrict axial rotation between the first mandrel and the second mandrel when the first mandrel is engaged to the second mandrel.
Abstract:
A downhole coupling system for joining together two segments of a tool string includes two mandrels, each having an interlocking interface at an end that abuts the adjacent mandrel and to communicate torque from one mandrel to the next. Each of the mandrels includes a threaded exterior surface, with the threaded surfaces have opposing thread directions or differing thread pitches. The coupling includes mating internal threads. A plurality of axial grooves is formed in each of the interior surface of the coupling and the exterior surface of one of the mandrels. A keyed latch ring having a plurality of internal keys and a plurality of external keys is included to engage the axial grooves, thereby rotationally locking the coupling relative to the first mandrel and second mandrel.
Abstract:
A wellbore completion system includes a tubular positioned in the wellbore such that an annulus is created between the tubular and a portion of the wellbore. The system further includes a gravel pack packer, a first packer positioned downhole of the gravel pack packer, and a second packer positioned downhole of the first packer. The gravel pack packer and the first packer define a first zone in the annulus, and the first and second packers define a second zone in the annulus. A wash pipe is positioned within the tubular and is positionable in a first position to allow fluid communication between a first port and the first packer and a second port and the second packer. The wash pipe is positionable in a second position to allow fluid communication between the first port and the first zone and the second port and the second zone.
Abstract:
A method for controlling fluid flow through a wellbore by introducing a plug with a variable choke into the wellbore, setting the plug in the wellbore, and mechanically adjusting the variable choke in the wellbore, thereby controlling a flow rate of a fluid through the plug. A plug that can control fluid flow through a flow passage in a wellbore, where the plug can include a body, an annular seal element that prevents fluid flow through an annulus between the plug and the wellbore, and a variable choke, where a closure member of the choke is mechanically rotated downhole to adjust a fluid flow rate through the choke. A method that can include producing fluids from two zones and using a plug to control a ratio of the fluids in a produced mixture.
Abstract:
A seal bore protector for protecting a seal bore of a rotating control device (RCD) is provided. The seal bore protector includes a cylindrical body, a throughbore extending through the cylindrical body, and a sealing element disposed around an external surface of the cylindrical body. The sealing element includes a first sealing ring, a second sealing ring, and a sealed area between the first sealing ring and the second sealing ring. The sealed area is fluidly coupled with a port when the seal bore protector is installed in the rotating control device.
Abstract:
A cement composition for use in a well that penetrates a subterranean formation comprising: cement; water; and an additive comprising zirconium dioxide, wherein at least a portion of the zirconium dioxide is in a metastable tetragonal phase, and wherein some or all of the zirconium dioxide that is in the metastable tetragonal phase transforms to a stable monoclinic phase after a stress is applied to the cement composition. The additive also reduces the dimensions of a crack located within the set cement composition. A method of cementing in a subterranean formation comprising: introducing a cement composition into the subterranean formation.
Abstract:
A wellbore formation system includes a downhole cutting tool having a body and at least one cutting element. A sensor is coupled to the downhole cutting tool, and the senor includes a transmitter configured to transmit a signal prior to wear on a portion of the downhole cutting tool reaching a first amount. The sensor ceases transmission of the signal when the wear on the portion of the downhole cutting tool reaches the first amount.
Abstract:
Systems, methods and devices for dielectric borehole imagery are disclosed. Systems may include one or more transmitters that induce, at azimuthally-spaced positions on a borehole wall, a plurality of fields having components in non-coplanar directions within a formation; one or more directionally sensitive receivers that sense the components caused by each of the one or more transmitters; and a controller that processes signals received from the one or more directionally sensitive inductive sensors to provide a set of measurements representative of dielectric parameters at two or more azimuthal positions within the borehole.
