| 20110252893 | DEVICE FOR MEASURING RATES IN INDIVIDUAL PHASES OF A MULTIPHASE FLOW - A device for measuring rates in individual phases of a multiphase flow, such as in flow of hydrocarbon fluid through a pipe line, comprising a venturi having, seen in the flow direction thereof, a first inlet portion with deceasing cross-section, a second intermediate portion with mainly uniform cross-section, and a third outlet portion with increasing cross-section, and being situated within the pipe line. According to the present invention, the venturi is provided with a number of sensors, and the sensors are arranged in mutual distance at different cross-section areas along at least the first of the three portion of the venturi as thereby being able to determine a pressure profile along the venturi as a base for estimating rates for actual rates of the flow. | 10-20-2011 |
| 20110247697 | METHOD OF PROCESSING FLUID FROM A WELL - There is described a method of processing fluid from a well. In an embodiment, a fluid processing system is operable to process fluids from a well in dependence on a plurality of controllable system parameters. The parameters are adjusted between respective first and second parameter values, and the first values define a first operational configuration and the second values defining a second, different operational configuration. The adjustment is carried out such that the system is balanced whilst adjusting the parameters. This may be done by adjusting the value of each parameter simultaneously along linear curves from a first initial value to a second end value. In the second configuration, activation or deactivation of a compressor ( | 10-13-2011 |
| 20110235057 | METHOD FOR MEASUREMENT OF THE THICKNESS OF ANY DEPOSIT OF MATERIAL ON INNER WALL OF A PIPELINE - A method is provided for measurement of the thickness of any deposit of material on the inner wall of a pipeline at least partly filled with a medium including hydrocarbons, the medium being for instance oil or natural gas, wherein the method includes: projecting infrared light onto the inner wall of the pipeline along a line corresponding to the intersection between the inner wall of the pipeline and a cross-sectional plane of the pipeline; registering an image of the infrared light projected on the inner wall of the pipeline; and determining the thickness of any deposit of material on the inner wall of the pipeline based on the registered image. | 09-29-2011 |
| 20110214884 | LINING OF WELL BORES WITH EXPANDABLE AND CONVENTIONAL LINERS - Reducing the diameter of a well bore has many advantages. To achieve this a subsurface well bore is provided comprising one or more expandable sleeve components, preferably expandable liners ( | 09-08-2011 |
