Problems solved by technology

Apart from oil and/or gas the systems also contain water, solid particles such as sand and other unwanted matter that negatively affects the function and life of the system.
Thus, in a system/equipment geometry like a valve tree or a manifold there may be a number of critical points where erosion affects the system/equipment.

Embodiment Construction

[0040]An embodiment of the present invention as shown schematically in FIG. 1 comprises an erosion adviser or module capable of handling and running computer programs, which computer programs are provided with data that are either stored in memories of the module as well as external data provided via input means, where the external data may come from a plurality of different types of sensors, data from other modules, and data entered by a user via keyboards, touch panels and the like.

[0041]The module may further comprise filters for filtering signals from sensors, A / D-converters for converting and sampling the signals and a micro processor. The micro processor comprises a central processing unit CPU performing the functions according to the present invention that will be described by way of example. The micro processor further comprises a data memory and a program memory. The result from the functions may be stored in appropriate memory means, displayed to a user via display means a...

Abstract

A method of providing information regarding erosion in an oil and/or a gas production system, which system includes at least one equipment/piping, the method including the steps of obtaining CFD results regarding hot spots in the equipment/piping from a CFD analysis of the equipment/piping for a range of pressures, flow rates and sand rates; and to, during production, obtaining data regarding erosion rates in a particular location in the system; and combining the data regarding erosion rates and CFD results to estimate and monitor sand erosion rates in the hot spots of the system. Further disclosed is a module performing the method steps as well as a computer program.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application is a continuation of pending International patent application PCT / IB2010 / 003334 filed on Dec. 22, 2010 which designates the United States and claims priority from Norwegian patent application 20093580 filed on Dec. 22, 2009, the content of which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to production systems for fluids such as oil and gas, which could contain particles that cause erosion inside the system.BACKGROUND OF THE INVENTION[0003]The modern off-shore production of oil and gas comprises complex production systems from the wells to platforms and also further to shore. Apart from oil and / or gas the systems also contain water, solid particles such as sand and other unwanted matter that negatively affects the function and life of the system.[0004]Sand and other abrasive materials are one major concern regarding the function and life of the system where erosion ...
