Model-based drilling fluid flow rate estimation using Venturi flume
Monitoring the flow rate out of the well is critical for good control of the downhole pressure in drilling operations. In this feasibility study, we explore the possibility of using a Venturi flume to provide a cost-effective measurement of the flow rate, with improved accuracy compared to conventional methods. A Venturi flume has been simulated both using CFD and a simplified 1D model. By prop...
متن کاملFrame Rate Up-conversion Using HOE (Hierarchical Optical flow Estimation) Based Bidirectional Optical Flow Estimation
We propose a frame rate up-conversion algorithm using bidirectional optical flow estimation at each pixel based on a previously proposed Hierarchical Optical flow Estimation (HOE) algorithm. The HOE is extended from unidirectional flow estimation to bidirectional flow estimation in which a 3×3×2 multi-dimensional filter and a motion compensated image method are used for high accuracy of flow es...
متن کاملImproved Rheological Model of Oil-Based Drilling Fluid for South-western Iranian Oilfields
In this study, predictive capabilities of apparent viscosity of oil-based drilling fluids which is used in National Iranian South Oilfields Company (NISOC) were evaluated using Newtonian and non-Newtonian models to drive a new suitable equation. The non-Newtonian models include Bingham plastic, Power law, Herschel-Bulkley, Casson, and Robertson-Stiff. To validate the results, the calculated vis...
متن کاملFluid experimental flow estimation based on an optical-flow scheme
We present in this paper a novel approach dedicated to themeasurementof velocity influid experimental flows through image sequences. Unlike most of the methods based on particle image velocimetry (PIV) approachesused in that context, theproposed technique is an extension of ‘‘optical-flow’’ schemes used in the computer vision community, which includes a specific enhancement for fluid mechanics ...
متن کاملDense Fluid Flow Estimation
In this paper we address the problem of estimating and analyzing the motion in image sequences showing uid phenomenon. Due to the great deal of spatial and temporal distortions that luminance patterns exhibit in images of uid, standard techniques from Computer Vision, originally designed for quasi-rigid motions with stable salient features, are not well adapted in this context. In that prospect...
