Determination of constant coefficients of Bourgoyne and Young drilling rate model using a novel evolutionary algorithm

M. Anemangely; A. Ramezanzadeh; B. Tokhmechi

Volume 8, Issue 4 , October 2017, , Pages 693-702


  Achieving minimum cost and time in reservoir drilling requires evaluating the effects of the drilling parameters on the penetration rate and constructing a drilling rate estimator model. Several drilling rate models have been presented using the drilling parameters. Among these, the Bourgoyne and Young ...  Read More

Numerical modeling of the effects of joint hydraulic aperture, orientation and spacing on rock grouting using UDEC: A case study of Bakhtiary Dam of Iran

Omid Saeidi; Ahmad Ramezanzadeh; Farhang Sereshki; Seyed Mohammad Esmaeil Jalali

Volume 4, Issue 1 , January 2013, , Pages 15-26


  This study aims at presenting a numerical model for predicting grout flow and penetration length into the jointed rock mass using Universal Distinct Element Code (UDEC). The numerical model is validated using practical data and analytical method for grouting process. Input data for the modeling, including ...  Read More
