... ABSTRACT A database of core-derived mechanical properties measurements has been used to develop new empirical correlations relating rock strength and compressibility to associated petrographic and petrophysical data. Automated fitting procedures translate these empirical observations...

... resolution, surface seismic data integrated with electromagnetic resistivity log measurements improve the description of rock properties by considering the coupled effect of pore space and fluid saturation in the joint acoustic and electrical domains. The key aspect of the proposed inversion is that it does...

... adsorbed to the surface of a solid: (1) G s = V L P P + P L Where G s is the adsorbed gas volume in scf/ton and p is pressure in psia. V L , the Langmuir Volume, is the maximum volume of gas that can be adsorbed by the rock. P L , the Langmuir Pressure...

... Step 1b: Post the Petrophysical evaluation, a rock physics modeling exercise is carried out wherein relationship between elastic properties (like P-wave, S-wave and Density) and Petrophysical rock properties are established. The RPM model used for the unconsolidated and tight sands facies found...

... ABSTRACT: Increase in subsurface temperature causes changes in physical & mechanical properties of rocks thereby causing instability in the strata which results in rock failure & surface subsidence. In this study, sandstone rock samples were collected from the Damodar River Valley...

...1. INTRODUCTION Rock masses are composed of intact rock blocks, separated by discontinuities. Deformation of rock masses occur largely along discontinuities, although deformation of intact blocks can also occur; therefore, the stiffness of a rock mass is a function of the properties of the intact...

... Abstract Disc cutters are the dominant cutting tools used on tunnel boring machines (TBM), as well as many other mechanical excavation units. One approach to estimate disc cutter wear life is to use Cerchar Abrasivity index (CAI). In this paper, the relationship between key rock properties...

... ABSTRACT: In view of the physical–chemical properties of CO 2 , this paper studied the impact of CO 2 –brine–rock interaction on rock properties and fracture propagation during supercritical CO 2 fracturing in Chang-7 tight sandstone. A series of static soaking experiments and true triaxial...

... Abstract Rock classification can enhance fracture treatment design for successful field development in organic-shale reservoirs. Rock brittleness and elastic properties are important parameters to be considered in selection of the best candidate zones for fracture treatment. However...

... Abstract The heterogeneity in carbonate rocks, made it hard for Geoscientists and Reservoir Engineers to define a universal classification methodology that is able to honour the critical reservoir static properties. Most classifications, like, lithofacies, capillarity and textural methods have...

... ABSTRACT: A suite of strength tests, in compression and extension, acoustic properties measurements, and sample characterization using several techniques have been performed on a suite of mud rocks. The samples range from Miocene through Late Jurassic in age, occur at in situ stresses ranging...

... ABSTRACT: Twenty-two rock samples having different rock properties are subjected to a set of experimental program in the laboratories of Mining Engineering Department, Istanbul Technical University. In the first stage, rock samples are subjected to a large program of rock mechanics tests...

... property parameters may affect the wear prediction considerably. This holds especially for the exponential wear prediction equation. The observed high sensitivity, combined with large variations in rock properties, can be a cause of the often poor correlations between the predicted and observed rates...

... Abstract A new technique is presented for a more effective description of the vertical variability of reservoir rock properties that are typically obtained or derived from wireline logs or determined from laboratory measurements of core samples. Rock properties and other data available...
