  • Patent number: 10358883
    Abstract: A downhole tool assembly includes a downhole tool and an anchor. The anchor is positionable at a downhole work site and includes a wet-connect port for engaging a battery pack. The tool operates until the battery runs low on power, when a low battery power alert is activated. The tool may be anchored at the work site while the battery is disconnected and retrieved to the surface for replacement. One or more charged batteries are then deployed and connected to the tool without having to remove the tool from the worksite or reposition the tool. The tool may be coupled to a wireline cable or a slickline cable or coiled tubing having a conductive wire for delivering low-voltage power to the tool. While the low-voltage power may not be adequate to operate the tool at full load, the power may be used to charge the tool during downtime.

  • Publication number: 20140196893
    Abstract: Many wellbore service operations involve placing a line in the wellbore. The line may be used to transmit power to downhole tools, convey signals from downhole-measurement instruments, or both. A problem associated with such operations involves drag forces experienced by the line as process fluids flow through the well, particularly the interior of a tubular body such as casing. The drag forces may cause the line to fail. Magnetizing the line solves this problem. During deployment, the line will migrate and become attached to the casing. Drag forces are significantly reduced because the line is no longer surrounded by moving fluid.

The sensor assemblies are coupled to a casing string (e.g., the exterior of the casing), and may detect RFID tags or other properties of material (e.g., fluids) in an annulus surrounding the casing string. Limited battery power for the sensor assemblies and for assemblies for communicating sensed data may be a concern, and the sensor assemblies and communication assemblies may therefore operate in different modes of varying power consumption. In certain modes, sensing operations are curtailed (or expanded) depending on particular requirements. In one case, sensor operation is expanded during active portions of a cementing operation, and curtailed prior to and thereafter. Different triggering events may cause the sensor assembly to operate in different modes at different sensing frequencies.

    Abstract: A sensor is configured to sense pressure in an isolated or subterranean environment. The sensor is configured to act as a capacitor with a capacitance that varies as a function of pressure. The sensor has a robust design with minimal moving parts, and in which any parts that do move do not communicate electrically through direct electrical conduction (e.g., through conductive leads). Instead, moving parts that participate in the performance of sensor as a capacitor receive and dispense electrical charge only through a dielectric fluid (e.g., a gas or liquid within the sensor). This may reduce hysterysis, lag, and/or friction with respect to pressure-dependent capacitor designs in which wiring is connected directly to moving parts.

    Abstract: A method and apparatus for controlling the operation of a well which is not flowing or in which fluid is pumped or injected into the well utilising a downhole located pressure monitoring device which is operative to monitor a characteristic pressure profile of the well, and to respond and generate a triggering output when a significant deviation to the pressure profile is introduced into the well as a control signal to the monitoring device by comparing two separate pressure profiles within a certain time span, the device only generating a triggering output when the same pressure profile is monitored twice within the time span; and an actuator which is initiated into operation to control any required operation of the well when the monitoring device responds to the control signal and generates the triggering output.

  • Patent number: 8490719
    Abstract: A method for maintaining pressure in a wellbore during drilling operations includes the steps of providing fluid from a reservoir through a drill string, circulating the fluid from the drill string to an annulus between the drill string and the wellbore, isolating pressure in the annulus, measuring pressure in the annulus, calculating a set point backpressure, applying back pressure to the annulus based on the set point back pressure, diverting fluid from the annulus to a controllable choke, controllably bleeding off pressurized fluid from the annulus, separating solids from the fluid, and directing the fluid back to the reservoir. An apparatus for maintaining pressure in a wellbore during drilling operations includes an adjustable choke for controllably bleeding off pressurized fluid from the wellbore annulus, a backpressure pump for applying a calculated set point backpressure, and a processor for controlling the adjustable choke and backpressure pump.

  • Patent number: 8430162
    Abstract: A technique facilitates monitoring of conditions which are prone to cause scale precipitation around downhole equipment. The technique also enables a local, downhole reaction to the potential for precipitation of scale. A downhole scale monitoring and inhibition system may be provided with a measurement module and injection module. The measurement module monitors at least one downhole parameter indicative of the potential for scale formation. In response to data output from the measurement module, the injection module is operated to provide downhole, local injections of an inhibitor chemical.

  • Patent number: 8360148
    Abstract: Example methods, apparatus and articles of manufacture to measure gas reservoir formation pressures are disclosed. A disclosed example method includes positioning a downhole bubble sensor in a wellbore formed in a geological gas reservoir formation, trapping a fluid in a portion of the wellbore including the bubble sensor, pressurizing the trapped fluid, reducing pressurization of the fluid until the bubble sensor detects one or more bubbles in the fluid, recording a pressure of the fluid when the bubble sensor detects the one or more bubbles, and determining a formation pressure of the gas reservoir from the recorded pressure.

  • Patent number: 8302687
    Abstract: Earth formations are characterized by using an array of electrodes which can measure streaming potentials in the formation, and by interpreting the data obtained by the electrodes. The electrodes are placed on a wireline tool, a LWD tool, or in a fixed manner about a completed wellbore. The measured streaming potentials are generated by drilling with an overbearing pressure, slitting the mudcake in a borehole, acid injection, or any of various other manners which causes fluid movement. The data obtained is interpreted to locate fractures, measure formation permeability, estimate formation pressure, monitor drilling fluid loss, detect abnormal pressure, etc. Particularly, a streaming potential voltage transient having a double peak profile signifies the presence of a formation fracture.

  • Patent number: 8272438
    Abstract: Systems and methods are disclosed for accurately determining a pore pressure of a subsurface formation (20) penetrated by a wellbore (40). The systems and methods provide for measuring pressure and temperature at a measuring location proximal to the wellbore for a predetermined amount of time, storing the measurements, communicating the measurements and processing the pore pressure from the pressure and temperature measurements. The measuring location may be a location in a channel (50) drilled from the wellbore into the formation.

  • Publication number: 20120227961
    Abstract: A method for determining annulus/wellbore fluid pressure, which is corrected for movement of a pipe string into or out of a wellbore, includes determining an initial annulus fluid pressure in the wellbore. Determining the initial annulus fluid pressure may include measuring a fluid flow rate into the wellbore and/or measuring a fluid pressure in the annulus proximate the surface. A rate of movement of a pipe string into or out of the wellbore is also determined. The initial annulus fluid pressure is adjusted to a corrected annulus fluid pressure by an amount which is a function of the rate of motion of the pipe string, a surface area of the outer wall of the pipe string and a surface area of the inner wall of the wellbore.
