Abstract: The invention relates to a cementing tool for use in oil and gas well decommissioning operations, in particular so called perforate, wash and cement procedures. The tool (1) is designed for running in a well on drill string and for jetting cement through previously formed perforations in the casing (10) to fill the outer annulus (9) with cement. The tool (1) has a cylindrical wall (3) which is formed from steel (11) and elastomeric (5) elements, whereby it is expandable between a first diameter in which it may be run down the well and a second, larger diameter deployed during cementing operations. (FIG. 2).

Abstract: The invention relates to a method of conducting a perf wash cement (“P/W/C”) abandonment job in an offshore oil or gas well annulus, in particular the washing or cementing operation using a rotating head with nozzles dispensing wash fluid or cement at pressure. A new design of bottom hole assembly is proposed in which the cementing tool has a relatively large diameter in order to optimize pressure whilst the wash tool has a relatively small diameter. The wash process, for a number of reasons, appears to be less sensitive to tool diameter and making the wash tool smaller reduces the overall risk of stuck pipe.

Abstract: Implementations described and claimed herein provide systems and methods for extending reach in a wellbore in oil well operations. In one implementation, a first coiled tubing string has a first coil interior surface, and a second coiled tubing string is disposed within the first coiled tubing string and has a second coil exterior surface. An annulus is defined by the first coil interior surface and the second coil exterior surface. The annulus is sealed proximal to a top end of the first coiled tubing string via a first seal and sealed proximal to a bottom end of the first coiled tubing string via a second seal. A fluid is sealed within the annulus at a pressure.

Abstract: Implementations described and claimed herein provide systems and methods for electronic discovery management. In one implementation, a staging path from source(s) to a staging area in a target location is generated automatically in connection with a collection request. Criteria for the collection request is obtained automatically and an encrypted export key for the collection request is captured using first robot(s). An export of a responsive data collection is obtained automatically from the source(s) using the first robot(s). The responsive data collection is exported along the staging path based on the criteria and the encrypted export key. An image of the responsive data collection is generated in the target location by sending parameter(s) to second robot(s), and the collection request is fulfilled by triggering a compression of the image of the responsive data collection into forensic container(s) using the second robot(s).

Abstract: A high pressure core chamber for use in collecting pressurized core samples from a reservoir is equipped with at least two high pressure access valves, allowing the core chamber to also function as a vessel for various high pressure experiments. In some embodiments, the core chamber is also equipped with a heater, allowing high pressure, high temperature experiments, and thus duplicating reservoir conditions. Various assays using the core chamber are also described.

Abstract: A core-in-shell heat exchanger, a method of fabricating the core-in-shell heat exchanger, and a method of exchanging heat in a core-in-shell heat exchanger disposed on a slosh-inducing moving platform are described. The method of exchanging heat includes introducing a shell-side fluid into a shell of the core-in-shell heat exchanger and introducing a fluid to be cooled into each of one or more cores of the core-in-shell heat exchanger, the one or more cores being arranged along an axial length of the shell with a plurality of baffles disposed on either side of the one or more cores along the axial length of the shell to reduce slosh of the shell-side fluid. The method also includes draining excess shell-side fluid using a plurality of drains, at least two of the plurality of drains being disposed on opposite sides of one of the plurality of baffles.

Abstract: Using microseismic analysis to identify and quantify the hydraulic fracture interaction in the Earth formation. Identification of the interaction is based on the magnitude of the events and therefore independent of the location uncertainty. Quantification of the interaction is location based.

Abstract: The invention relates to very precisely measuring changes in thickness of pipe walls to determine corrosion rate prior to any significant corrosion loss. The thickness is determined by ultrasonic testing where many measurements of the wall thickness are taken at the same spot by a fixed sensor and errors associated with noise and temperature changes are substantially eliminated. A highly sensitive receiver converts each reflected pulse to waves that are averaged with other pulse measurements. The resulting average wave is analyzed so that each waveform is analyzed to identify the extrema and inflection points of each reflected pulse. The resulting analysis provides a far more accurate determination of the time between reflected pulses. As a result, a far more accurate picture of corrosion at the location of the wall of the pipe can be determined within weeks with a high degree of confidence.

Abstract: A suspension head (11) is provided for connection between a high pressure riser (8) and a subsea wellhead (9), for use in drilling and completion operations in which a jack-up rig (1) is employed and a blowout preventer (7) is installed on the jack-up rather than on the wellhead. The use of the suspension head (11) offers improved safety and convenience, allowing the riser (8) to be isolated from the wellhead (9) in emergencies or for carrying out certain operations which would otherwise require the installation of a temporary plug.
