  • Patent number: 11041367
    Abstract: An inflow control device (“ICD”) is in production tubing in a wellbore, and used to control a flow of fluid through the ICD. The ICD is adjustable in response to an external force, which is selectively applied by an actuator that is included with a bottom-home assembly (“BHA”). The BHA is deployed on coiled tubing, and anchored in the wellbore to isolate the coiled tubing from resultant or counter forces generated when adjusting the ICD. Fluid is optionally injected into the coiled tubing on surface, and directed into the wellbore from the BHA. A latching arm is included with the actuator, which is equipped with a profile that matches a profile on the ICD to facilitate engagement between the arm and the ICD.

    Abstract: Systems and methods for signaling the detection of a fluid change in a wellbore can be used during wellbore operations, such as cementing a casing in the wellbore. The systems and methods involve using burst discs to provide a pressure pulse that can be detected uphole and there by provide a signal related to when a fluid change has reached a predetermined position in the wellbore. The burst discs can be activated to prevent fluid flow in a portion of the wellbore by a sensor that detects a property that is different between two fluids. Once activated, the pressure of the fluid on the burst discs subsequently ruptures the burst disc and creates the pressure pulse.

    Abstract: A hang-off tool for supporting a tool inside a tubular member includes a logging string configured to generate logging data, a computing system coupled to the logging string and configured to communicate the logging data to another tool, and a radially expandable member having a retracted position and an expanded position. The radially expandable member is configured to engage a radially-increased profile of an inner surface of the tubular member in the expanded position to support the hang-off tool. The radially expandable member is also configured not to engage the radially-increased profile in the retracted position.

    Abstract: A system for detecting when a plunger reaches a bottom of a well includes a pressure sensor configured to measure a pressure of the well and provide a measured pressure output. Derivative calculation circuitry calculates a derivative of the measured pressure output. Detection circuitry detects when the plunger reaches the bottom of the well based upon the calculated derivative.

  • Patent number: 8977501
    Abstract: Provided are a system and method for identifying planned markers while drilling a borehole. In one example, the method includes obtaining a plan containing planned markers that each corresponds to a baseline marker from an existing well. Each of the baseline markers corresponds to a waveform from a log file obtained from the existing well and is associated with a waveform representation of the corresponding waveform. Each of the planned markers is associated with an estimated true vertical depth (TVD) value. A second log file corresponding to the borehole is obtained that contains waveforms representing formation information detected within the borehole. The second log file is scanned for a planned marker based on the estimated TVD value and the waveform representation of the baseline marker corresponding to the planned marker. At least one match may be identified and reported for the planned marker.

  • Publication number: 20150047839
    Abstract: Wireless downhole sensor technology is being deployed in oil and gas wells. System components are inductively coupled, which enables remote placement of apparatus on the outside of wellbore conduit without the need for any wired connection. These systems make use of a pair of conductive elements that need to be aligned in the well. Embodiments of the present invention provide techniques to correctly space out the wellbore completion string so that the down-hole conductive elements will be properly aligned and within proximity to establish wireless connectivity, as the wellbore completion string is set and the tubing hanger is landed inside the wellhead housing of the well.

  • Patent number: 8955603
    Abstract: A system of couplings and method of use of the couplings to locate a downhole tool connected to coiled tubing, such as a bottom hole assembly, within a selected segment of a casing string. The selected segment of casing may be a ported collar or ported housing that permits the treatment and/or stimulation of the adjacent well formation. The system of couplings may be two, three, or four couplings spaced apart at predetermined lengths. The predetermined lengths may be shorter than typical lengths of casing segments. The distance between the first and second coupling may be substantially identical to the distance between the third and fourth coupling. The use of distances between the couplings that are shorter than the length of conventional casing segments may provide surface indicators as to the location of the bottom hole assembly with a higher confidence than relying on a traditional tally sheet.

    Abstract: A downhole apparatus including a tool body and a sealing element disposed within the tool body. Also, at least one sensor disposed on the tool body, wherein the sensor is configured to take measurements from a well and wherein the sensor measures an actuation condition, the sensor signals the sealing element to actuate. Also, a method of sealing a portion of a well including disposing an automatic packer in a well, wherein the automatic packer includes a tool body, a sealing element disposed within the tool body, and a sensor disposed on the tool body. The method also includes measuring a condition within the well, determining an actuation condition with the sensor, and expanding the sealing element into contact with an inner diameter of the well when the actuation condition is determined.

  • Patent number: 8950483
    Abstract: A positional feedback system includes a seal assembly coupled to a running tool, the seal assembly having a seal ring and an energizing ring positioned between a hanger and a subsea wellhead. The energizing ring moves relative to the seal ring from an unset position to a set position to seal to the wellhead and the hanger. The system includes a magnet disposed on the energizing ring and having a magnetic field. One or more sensing devices are disposed on running tool and positioned in the magnetic field of the magnet in the set position and the unset position. The sensing devices are configured to communicate with a surface platform when the rare earth magnet passes a magnetic field through the sensing devices.

  • Publication number: 20150027695
    Abstract: A system and method for forming a cavern in a formation beyond a cased wellbore utilizes a locator to position a perforating gun in the wellbore for forming axially aligned, spaced-apart perforations through the casing. The locator has a stationary portion, run in and anchored in the wellbore below a zone of interest. The perforating guns have a moveable portion of the locator at a downhole end and are run in and coupled with the stationary portion. Where two or more guns are used to form the perforations, the guns are indexed relative to one another for forming the offset perforations. The guns are tripped from the wellbore and a wash tool having a moveable portion of the locator at a downhole end is run in and coupled in the wellbore. The locator acts to delimit a reciprocation of the wash tool along the space-apart perforations for delivering a non-abrasive fluid therethrough for forming the cavern.
