摘要： Disclosed is a method and associated computer program and apparatus for characterising changes within a subsurface volume between a first time and a second time. The method comprises obtaining first seismic data corresponding to the first time and processing this data to obtain a seismic image of the subsurface volume. This processing is reversed for relevant portions of the seismic image to obtain relevant portions of first seismic data. Changes within the subsurface volume between the first time and the second time are characterised by estimating the changes between second seismic data corresponding to the second time and the relevant portions of first seismic data.

摘要： An improved solution for estimating the flow rate of a fluid in a line of a hydrocarbon production installation, during production. Systems and methods for producing hydrocarbons on a line of a hydrocarbon production installation can include at least two devices adapted each for providing an estimate of the flow rate of a fluid in the line based on respective data. The devices include at least one metric counter, and the data relative to the provision of an estimate of the flow rate by the metric counter include a measurement done by at least one sensor of the metric counter on the fluid. Further, data can be determined relative to the provision of an estimate of the flow rate by the devices, and a DVR process involving the determined data, the reconciliation being conditioned by at least a substantial equality between the estimates of the flow rate of the fluid.

摘要： A method for forming an offshore well comprises forming a well structure (1) which includes a lower well portion extending below a seabed and an upper well portion (2) extending upwardly between the seabed (18) and a terminating upper end (3) of the well structure, wherein the well structure comprises a plurality of concentrically arranged tubular strings (22) and at least one annulus (48) defined therebetween. The method includes steps for minimising the bending stiffness of the upper well portion. In one example minimising the bending stiffness of the upper well portion may comprise partially filling at least one annulus with cement (52) to a height which: is intermediate the seabed and the terminating upper end of the well structure. In another example minimising the bending stiffness of the upper well portion may comprise providing a cement disruptor within at least one annulus and locating cement within said at least one annulus to define a cement sheath, wherein the cement disruptor, for example sleeve (122), reduces resistance of at least a portion of the cement sheath to bending of the upper well portion. In a further example minimising the bending stiffness of the upper well portion may comprise locating a flexible material within at least one annulus; and In a further example minimising the bending stiffness of the upper well portion may comprise varying the bending stiffness along at least one of the plurality of tubular strings.

摘要： A method and an apparatus for battery modelling. The method includes acquiring battery information from a sensor attached to a battery, the battery information including at least a terminal voltage and a load current; classifying, the battery information as effective data or ineffective data based on a phase of a battery cycle during which the battery information is acquired; identifying one or more parameters of the circuit model associated with the battery based on the effective data; and generating an estimation of a state of the battery using the circuit model having the one or more parameters identified using the effective data. Further, a circuit model is identified using effective data.

摘要： The disclosure relates to a method for detecting water in a tensioning buoy of a riser column of an installation located in an aquatic environment, the method including, in succession, steps of: defining a representative standard echo; emitting the ultrasonic signal on a wall of the buoy; measuring a representative response echo due to the reflection of the ultrasonic signal in the buoy; comparing the representative response echo to the representative standard echo; and determining whether water is present in or absent from the buoy from the comparison.
