Permeability Prediction by Hydraulic Flow Units—Theory and Applications
SPE Formation Evaluation, 1996SummaryAn improved technique based on the concept of hydraulic flow units or hydraulic units (HU's) is presented to calculate permeability distribution in uncored wells. Graphical probability methods, nonlinear regression, and the Ward's analytical algorithm are presented to perform cluster analysis on core data and identify prevailing HU's in a ...

Permeability Estimation Using Hydraulic Flow Units in Carbonate Reservoirs
Proceedings of Rocky Mountain Oil & Gas Technology Symposium, 2007Abstract This study focuses on the evaluation of formation permeability for a carbonate reservoir from well logs and core data using the concept of flow units. Characterization of carbonate reservoirs by flow units is a practical way of reservoir zonation. The study represents a petrophysical-based method that uses well loggings and core

Improved Method to Identify Hydraulic Flow Units for Reservoir Characterization
Energy Technology, 2015AbstractIdentification of hydraulic flow units (HFUs) is an important part of reservoir characterization. Rock samples within a given HFU are expected to have the same mean hydraulic radius. We show that the famous reservoir quality index‐flow zone indicator (RQI/FZI) technique and its recent modifications do not use the concept of mean hydraulic ...

Constrained clustering approaches to identify hydraulic flow units in petroleum reservoirs
Journal of Petroleum Science and Engineering, 2020Abstract Hydraulic flow units (HFUs) are recognized as volumetric regions that favor the flow of reservoir fluids. Their determination is made possible through correlations between data that are transferred from miscroscale to reservoir scale by upscaling.

Relationship Between Velocity and Permeability Using Hydraulic Flow Units
Proceedings, 2009Estimation of Relationships between velocity of P-wave and permeability by using usual method is difficult. In this study that is first research in Iranian oilfield we show that by grouping and sorting rocks into hydraulic units, we can establish relationships between velocity and permeability.

SPE Asia Pacific Oil and Gas Conference and Exhibition, 2004
Abstract The Carman-Kozeny formulation has been used as a basis to provide a new perspective of flow zone units (FZUs), by mapping similar rocks in terms of "Characteristic Envelopes", for different geological depositional environments. A large amount of data, covering several fields and different Australian basins, has been analysed.

Permeability Prediction Using Hydraulic Flow Units and Hybrid Soft Computing Systems
SPE Annual Technical Conference and Exhibition, 2001AbstractIn the last years, the concept of hydraulic flow units (HFU) has been used in the petroleum industry to improve prediction of permeability in uncored interval/wells. This concept is strongly related to the flow zone indicator (FZI) which is a function of the reservoir quality index (RQI).

RATIONALIZATION OF THE UNIT FOR DIAGNOSING THE FLOW RATE OF HYDRAULIC EQUIPMENT FOR MOBILE MACHINES
STATE AND DEVELOPMENT PROSPECTS OF AGRIBUSINESS. In the frame of the XXIII Agribusiness Forum of the South of Russia and the Exhibition «Interagromash» Volume 2, 2020The article presents a strength analysis of the flowmeter design used in the diagnostics nodes of mobile machine hydraulic units. The connection of the flow meter housing with the bracket has been simplified and adapted for a more robust sensor design, taking into account the strength and tightness of the threaded connection.

Experiment on morphological and hydraulic adjustments of step‐pool unit to flow increase
Earth Surface Processes and Landforms, 2019AbstractExceptional flood events with a return period of about 50 years can be destructive to step‐pool channel segments. However, field investigations and flume experiments have not examined the hydraulic and morphological feedbacks of step‐pool morphology during unsteady hydrographs of exceptional flood events.

2012 Power Engineering and Automation Conference, 2012
Considering the demand of various working status of slow dumping and fast return, a hydraulic system which can switch working conditions between large and low flow was designed. In the working condition of low flow, in order to achieve accurate casting, the two hydraulic cylinders were required moving synchronously and tracking a special displacement ...
