Abstract

This paper presents a detailed formulation of a rate of penetration (ROP) model, considering
many drilling parameters and conditions for obtaining maximum drilling rate as well as
minimizing the drilling cost.
A regression analysis technique has been usedfor ROP modeling in Mishref formation.The data
were extracted from routinely available mud and wirelinelogs. These data includes weight on
bit ,rotary speed,horse per square inch,and transit time.For ROP modeling, data of five wells
inHalfaya oil field in south Iraq were extracted.Statistical software called SPSS was used for
improving the modeling data and to perform linear and nonlinear multiple regression analysis.
This improving approach included detection the outliers of modeling parameters, grouping the
modeling data, moving average and finally applying the regression analysis.
Results of modeling showed that the grouping of modeling data exhibited good convergence
with actual data and the overall model of oil field could produce good fitness with the actual
data in both cases of linear and nonlinear models.Also,a good estimation of drilling cost could
be obtained when using this model.
