TL;DR: In this paper, a well test interpretation method based on the analysis of the time rate of change of pressure, together with the actual pressure response is discussed, and several field examples are provided to illustrate how the method simplifies the analysis process.
Abstract: In this paper, a well test interpretation method based on the analysis of the time rate of change of pressure, together with the actual pressure response, is discussed. A differentiation algorithm is proposed and several field examples are provided to illustrate how the method simplifies the analysis process. Interpretation of well tests is therefore easier and more accurate.

TL;DR: In this paper, the surface forces are expressed as a disjoining pressure isotherm, and its integral is the specific interaction potential isotherms, which can be used to determine the stable and metastable film-thickness profiles at the three-phase contact region for a given capillary pressure and/or curvature of the substrate.
Abstract: The wetting of mineral surfaces by water and oil is described by models of surface forces that become important when two surfaces approach each other. Force components are electrostatic, van der Waals, and structural. The electrostatic forces depends on brine pH and salinity, crude oil composition, and the mineral. The surface forces are expressed as a disjoining pressure isotherm, and its integral is the specific interaction potential isotherm. The specific interaction potential isotherm can be used to determine the stable and metastable film-thickness profiles at the three-phase contact region for a given capillary pressure and/or curvature of the substrate. This paper gives the contact angle.

TL;DR: In this paper, les parametres de la methode de calcul sont ameliores en tenant compte des experiences realizees sur les champs, and two representations des donnees sont comparees: utilisation of 2 ou 3 exposants and un facteur ralentissant la croissance de la courbe exponentielle.
Abstract: La permeabilite des roches est determinee en laboratoire par des mesures de spectrometrie RMN. Elle peut etre estimee a partir de la constante du temps de relaxation de la magnetisation longitudinale de l'hydrogene. Trois representations des donnees sont comparees: utilisation de 2 ou 3 exposants et d'un facteur ralentissant la croissance de la courbe exponentielle. Les parametres de la methode de calcul sont ameliores en tenant compte des experiences realisees sur les champs
