  • Patent number: 11143780
    Abstract: Apparatus and methods can be conducted in a multi-pipe structure to determine eccentricity of one or more pipes of the multi-pipe structure. A tool having a center axis as a symmetry axis of the tool can be used in which receivers are arranged as a number of pairs of receivers around the center axis of the tool. Each receiver of a pair can be disposed opposite the other receiver of the pair with respect to the center axis such that each pair is symmetrical with respect to the center axis of the tool. Eccentricity of one or more pipes of the multi-pipe structure can be determined based on the received responses at the receivers of the pairs.

  • Patent number: 10738590
    Abstract: A well casing is cemented in a well bore in a subterranean formation by pumping cement slurry down into the well casing so that the cement slurry flows up into an annulus surrounding the well casing. While pumping the cement slurry, the position of the top of the cement slurry in the annulus is sensed, and the rise of the sensed position of the top of the cement slurry in the annulus is recorded as a function of time. The recording is analyzed to evaluate the cement job. For example, the analysis may indicate a problem addressed by adjusting a cement plan for a future cement job, and the analysis may indicate a need to repair a location of the set cement by perforating the well casing at the location to be repaired, and pumping cement slurry down the well casing to fill the location to be repaired.

  • Patent number: 9540919
    Abstract: A one trip system for perforating and fracking multiple intervals uses a releasable barrier. The barrier can be an inflatable. A pressure booster system is associated with the BHA so that the existing hydrostatic pressure is boosted when the gun or portions thereof are fired. After firing in one interval, the BHA is raised and the barrier is redeployed and the pattern repeats. Instruments allow sensing the conditions in the interval for optimal placement of the gun therein and for monitoring flow, pressure and formation conditions during the fracturing. Circulation between gun firings cleans up the hole. If run in on wireline a water saving tool can be associated with the BHA to rapidly position it where desired. A multitude of perforation charges mounted in the BHA can be selectively fired by selected corresponding detonator based on a predetermined sequence or surface telemetry command.

In one embodiment, the method and system may be utilized before, during, and after contaminating operations to monitor a water aquifer and generate reports detailing the effect of the contaminating operations on the water aquifer. The reports, and associated raw data, may be used as legal documents. For example, in one embodiment, an independent company is responsible for monitoring the aquifer and generating reports, which are then submitted to all interested parties, including the state for regulatory purposes.

    Abstract: A down hole surveying tool (10) is for directional surveying of boreholes. The tool (10) includes a body (11) which accommodates a composite sensor device (17). The sensor device (17) is supported for rotation about an indexing axis (4) in a rotary mount (31) which provides an indexing platform (33). The sensor device (17) can be indexed about the indexing axis between two indexing positions which are 180 degrees apart. An indexing mechanism (70) is provided for selectively indexing the sensor device (17) about the indexing axis (4). The sensor device (17) includes a two-axis gyroscope (13) and a two-axis accelerometer (15) connected together and rotatable in unison. The indexing axis (4) is perpendicular to the two sensitive axes of the gyroscope (13) and the two sensitive axes of the accelerometer (15). The gyroscope (13) and accelerometer (15) are rigidly fixed with respect to each other to provide a sensor package which constitutes the composite sensor device (17).

  • Publication number: 20130104643
    Abstract: A tool for testing a tubular has a shaft with a fluid passageway connecting a first port and one or more second ports. A sealing element seals against the tubular member. The shaft moves relative to the sealing sleeve between an open position in which the first port is in fluid communication with the second port and a closed position in which the sealing sleeve closes the first port. An anchor secures the sealing sleeve relative to the tubular member to permit the shaft to move from the open position to the closed position.

    Abstract: A coiled member measuring device includes a main frame fixedly anchored in relation to the outer casing or the coiled member handling device of a well and an inner housing supported by the main frame for unrestricted lateral movement in at least two different directions transverse to one another and in a common plane oriented perpendicularly to an axial direction of the outer casing. Followers in the inner housing surround an axial passage receiving a coiled member such as coiled tubing or continuous rod therethrough. Two adjacent followers are supported in a V-shaped pattern for sliding movement diametrically opposite a third remaining follower. Sensors associated with the followers permit determination of overall circumference and length of the coiled member.

    Abstract: Method for quantitatively assessing connectivity for well pairs at varying frequencies. A time series of measurements (12) is chosen for each of the two wells such that the particular measurements will be sensitive to subsurface connectivity if it exists (11). The two time series may then be pre-processed by resampling to time intervals commensurate with response time between the two wells (13), detrending the measurements (14), and detecting and eliminating spiking noises (15). Then the time series are transformed to the frequency domain where coherence and phase between the two series are compared for varying frequencies (16). This comparison is used to make a determination of connectivity.

  • Publication number: 20120314540
    Abstract: Hollow rebar may be used for structural reinforcement in a drilled shaft and to provide access tubes for a sonic integrity testing probe. Rebar (short for reinforcing bar) is steel bar used as a tensioning device in reinforced concrete that holds the concrete in compression. According to the system described herein, hollow rebar may provide high strength reinforcement in the drilled shaft while at the same time providing an access tube for a sonic integrity testing process, such as crosshole sonic logging (CSL). The high strength hollow rebar, having ridges, threads and/or other appropriate surface deformations, provides improved adhesion to concrete, thus eliminating the problem of debonding associated with non-structural access tubes made of smooth PVC or steel pipe.
