Title : Volumetric flow estimation model for cuts and cavings, using ultrasound techniques

Abstract:

During the drilling process and for ensuring well stability, to employ effective technologies is very important, since it can be avoid shutdowns that generate non-production times. One of the direct indicators of the well mechanical stability is the volumetric flow of cuts and cavings, extracted during the process. Currently, in many wells this variable is manually and indirectly measured at one point in the process. This consists of an operator counting the filling time of a tray of known volume and installed at the end of the flow line and then relating these two parameters to obtain the volumetric flow (known volume / filling time). Therefore, by building a volumetric flow estimation device of a cuts and drilling cavities in the line, a continuous monitoring and geomechanical analysis of the well could be achieved. Hence, this paper is focused on studying a functional electronic model for volumetric flow estimation, based on the Doppler effect of acoustics generated by piezo-electrics, configured in phase array mode This mode allows the generation of a constructive wavefront directed to a desired angle, which encompasses with the Doppler effect flow measurement technique. Finally, the proposed estimation model is experimentally validated at the laboratory level using pipes with different acoustic impedances, in which a mixture of of mud and cavings is made to flow.

What will audience learn from your presentation?
• This research can help both companies and researchers seeking to implement technologies to ensure wellbore stability in the drilling process.
• The research provides information to build and improve a model for estimating drilling cuttings and slippage.
• It also provides an electronic design that can be implemented to build a phase array with the amount of piezo-electrics that the system requires.
