Title: Mitigation of buckling in subsea pipe-in-pipe systems
Inventor: Davide Gorgoglione
IPC: F16L59/147
Filed: 2019-12-12
Abstract: A subsea pipeline of pipe-in-pipe configuration comprises an inner pipe 14, an outer pipe 16 spaced radially from the inner pipe and an annulus 20 defined by the radial spacing between the inner and outer pipes. A series of longitudinally-spaced outward projections 22 extend radially outwardly into the annulus from the inner pipe and are movable longitudinally relative to the outer pipe. A corresponding series of longitudinally-spaced inward projections 24 extend radially inwardly into the annulus from the outer pipe and are movable longitudinally relative to the inner pipe. The inner pipe is movable longitudinally relative to the outer pipe, hence moving the outward projections between and relative to the inward projections (e.g. when the inner pipe is subject to thermal elongation or contraction in use of the pipeline). The pipeline may be buried to restrain the outer pipe. The annulus may be flooded, in which case the inner pipe is covered with wet insulation.

Title: Determining gas leak flow rate in a wellbore environment
Inventor: ANDREY FILIPPOV
IPC: G06N20/00
Filed: 2018-03-08
Abstract: An estimated gas leak flow rate can be determined using a teaching set of concentration profiles, a regression model implemented by a machine-learning subsystem, and a subset of attributes measured within an environment. The teaching set of concentration profiles can include gas flow rates associated with relevant attributes. The regression model can be transformed into a gas leak flow regression model via the machine-learning subsystem using the teaching set. The subset of attributes measured within the environment can be applied to the gas leak flow regression model to determine other attributes absent from the subset of attributes and an estimated gas flow rate for the environment. A gas leak attenuation action can be performed in response to the estimated gas flow rate.

Title: Method and system for downhole object location and orientation determination
Inventor: CRAIG MILNE
IPC: G01V11/00
Filed: 2015-05-15
Abstract: An orientation tool 22 with an orientation detector, preferably disposed downhole. The orientation detector may be offset rotatably mounted magnetic masses, where a magnetic detector detects the rotational orientation of the masses; the orientation detector may be a three-axis accelerometer or relative bearing sensor. A vibrational/acoustic source produces signals representing the detected orientation of the orientation tool. The signal is frequency modulated to encode information pertaining to the detected orientation, chosen from a selection of predetermined frequencies that represent predetermined orientations, preferably where no frequency is the harmonic frequency of another. The source may be a solenoid or piezo-electric tapper. The orientation tool is preferably co-located with an optical fibre 14, fixed together with a clamp 12 to a wellbore casing 10. The fibre may form a distributed acoustic sensor system, such that it can send optical backscatter/reflections to a signal processing apparatus and transmit the encoded signals of the orientation tool. A surface user can thus determine the orientation of the fibre with respect to the casing. Time-of-flight calculations may determine tool location.

Abstract: A suspension damping force control system and corresponding method are provided. The control system is configured to control a damping force of an actuator (502, Figure 4) of an active suspension system (104, Figure 4) of a vehicle (1, Figure 4) in response to an external disturbance of a wheel (FL, FR, RL, RR, Figure 4) with which the actuator is associated. The control system comprises one or more controllers (200, Figure 4). The control system is configured to: receive a sensed displacement parameter (Z, A) indicative of suspension displacement associated with the wheel; determine whether a condition is satisfied, wherein satisfaction of the condition requires the sensed displacement parameter to indicate a transition from a suspension displacing phase t1-t2 associated with the external disturbance to a suspension restoring phase t2-t3 associated with the external disturbance. Satisfaction of the condition depends on an amount of suspension displacement (Z) indicated by the sensed displacement parameter; and output a signal to control the damping force to be greater during the suspension restoring phase associated with the external disturbance, than if the condition is not satisfied, in dependence on satisfaction of the condition.

Title: Gas breakthrough analysis
Inventor: TAO YANG
IPC: E21B47/10
Filed: 2021-12-22
Abstract: Identifying a location of gas breakthrough within a completed production well includes obtaining production composition data and/or tracer data from the production well 510, preferably gas-oil ratio (GOR) data and analysing that data to determine whether gas breakthrough has occurred within the well 520. In response to determining that gas breakthrough has occurred, examining mud-gas data collected during drilling of the well to identify a gas breakthrough location where the gas breakthrough has occurred 530, preferably to an accuracy of 10 metres. The examined mud-gas data is preferably standard mud-gas data rather than advanced mud-gas data (amg) to enable real-time monitoring. Preferably a well intervention operation, such as sealing or bypassing, is performed to reduce production of fluid from adjacent the gas breakthrough location 540 spanning at least 10 metres above and/or below the gas breakthrough location. The mud-gas data examined may be 4D seismic, data or petrophysical data. A gas breakthrough may be determined to have occurred when the GOR exceeds a threshold or the fluid density falls below a threshold. The locating may involve determining where a methane component in the mud-gas exceeds a threshold or a tracer fluid concentration within the production fluid exceeds a threshold.
