PetroPhysical Analysis Of Reservoir Rock Of Fenchuganj ...
KEYWORDS: porosity, permeability, petrophysical properties, wireline logs. I. INTRODUCTION Petrophysics is the study of rock properties and their interactions with fluids (gases, liquid hydrocarbons and aqueous solutions). The amount of hydrocarbon present in a reservoir is a function of its porosity and its hydrocarbon saturation [1].

Prediction of rotary drilling penetration rate in iron ore ...
The ability to predict the performance and efficiency of drilling machines is very important in mining operations. The rock drillability is one of the most important parameters for mine planning, development and economics of mine operations. Also knowledge of drillability of rocks in engineering projects has key role to determine drilling costs.

Rock properties and mechanical behaviors | SpringerLink
Abstract. Rock physical and mechanical properties are very important parameters for geological engineering design and construction. For instance, in coal mining industry many geological disasters induced by mining were associated with misunderstanding of rock mechanical properties (Peng 1998a, Han and Peng 2002).
