Analysis of Vertical Fracture Length and Non-Darcy Flow Coefficient Using Variable Rate Tests

SPE Annual Technical Conference and Exhibition, 1980
ABSTRACT In this investigation, a new method is presented for predicting both the non-Darcy flow coefficient and vertical fracture length based upon single-point, variable flow drawdown tests of shallow, low permeability gas reservoirs.

The Impact of Compaction and Sand Migration on Permeability and Non-Darcy Coefficient from Pore-Scale Simulations

Transport in Porous Media, 2018
Compaction and sand migration are important problems in loosely consolidated and unconsolidated high-rate gas reservoirs, and proppants in the hydraulic fractures. Their impacts on permeability and non-Darcy flow are important for accurate estimation of well productivity.

Correction of non-Darcy Coefficient and How to Estimate It for Development Wells

SPE Asia Pacific Oil and Gas Conference and Exhibition, 2011
Summary Abadi gas field located offshore Arafura Sea, eastern Indonesia (Figure-1) was discovered by INPEX in 2000 and the appraisal activities have been carried out subsequently since then. Total 7 wells have been drilled and 8 DSTs have been conducted so far. The objectives of this work are to obtain more accurate non-Darcy coefficient

Prediction of Non-Darcy Coefficients for Inertial Flows Through the Castlegate Sandstone Using Image-Based Modeling

Transport in Porous Media, 2012
Near wellbore flow in high rate gas wells shows the deviation from Darcy’s law that is typical for high Reynolds number flows, and prediction requires an accurate estimate of the non-Darcy coefficient (β factor). This numerical investigation addresses the issues of predicting non-Darcy coefficients for a realistic porous media.

Correction of the Non-Darcy Coefficient for Completion Effects: Impact on the Prediction of Tangguh LNG Gas Well Deliverability

Proceedings of SPE Asia Pacific Oil and Gas Conference and Exhibition, 2001
Abstract The Tangguh LNG gas fields are situated in the Berau Bay, Irian Jaya, Indonesia. An extensive exploration and appraisal program was performed from1994 to 1998 which resulted in the discovery of 14.4 TCF of proved gas reserveswith substantial upside reserve potential.

A PORE NETWORK MODEL FOR THE CALCULATION OF NON-DARCY FLOW COEFFICIENTS IN FLUID FLOW THROUGH POROUS MEDIA

Chemical Engineering Communications, 2004
A computational method was developed to determine the correlation between permeability and the Forchheimer (non-Darcy) coefficient and to investigate numerically the factors that affect this correlation. The method is based on the construction of a 2-D random pore network. The porous medium is represented as a network of cylindrical pipes with randomly

Determination of Non-Darcy Flow Coefficient and Completion Skin from Multi-Rate Test Data with a Decreasing Effective Skin

SPE Nigeria Annual International Conference and Exhibition, 2023
Abstract Non-Darcy skin is always present in the gas, gas-condensate, and high Gas Oil Ratio (GOR) oil wells, increasing as the rate increases. However, the reverse is true in a well with a loading skin. This paper outlines the interpretation procedure and unmasking of the non-Darcy skin in a loading well with a new calculation approach.

Permeability and Form Coefficient Measurement of Porous Inserts With Non-Darcy Model Using Non-Plug Flow Experiments

Journal of Fluids Engineering, 2005
Permeability (K) and form coefficient (C) are the characteristic hydraulic properties of any porous medium. They are determined simultaneously, for known fluid thermo-physical properties by using the Hazen-Dupuit-Darcy model (HDD) to curve-fit the longitudinal global pressure-drop versus average fluid speed data from an isothermal, steady flow ...

New technique for determining rate dependent skin factor & non-Darcy coefficient

Journal of Natural Gas Science and Engineering, 2016
Abstract A non-Darcy flow develops in porous media when the velocity of reservoir fluids becomes extremely high because of the continuous narrowing of the cross section area of the flow and the convergence of flow streamlines. Therefore, the inertial effect increases significantly and the total pressure drop, required by fluids to move from the outer

Non-Darcy Coefficient in Fractured Rocks

58th U.S. Rock Mechanics/Geomechanics Symposium
ABSTRACT: In the present work, an experimental methodology was developed for measuring the high-velocity coefficient in fractured rocks. The measurements were carried out at reservoir conditions (high pressure and temperature), in four full-diameter (whole) samples of a naturally fractured gas and condensate ...
