Diamondoids have been of great interest in recent years due to their role in nanotechnology, drug-delivery and medicine. In this review paper we introduce at first the cage nature of diamondoid molecules (polymantanes, adamantologues), the variety of their crystalline lattice structures, the nature of their structural isomers, their stereoisomers, and their other molecular specificities are pre...

Nuclear magnetic resonance (NMR) diffusion-relaxation correlation experiments (D-T2) are widely used for the petrophysical characterisation of rocks saturated with petroleum fluids both in situ and for laboratory analyses. The encoding for both diffusion and relaxation offers increased fluid typing contrast by discriminating fluids based on their self-diffusion coefficients, while relaxation ti...

To extract all the oil from a well, petroleum engineers pump hot reactive chemicals into the well. These Enhanced Oil Recovery (EOR) processes need to be thoroughly monitored, since the injected fluids can seep out of the production oil wells and, if unchecked, eventually pollute sources of drinking water. There is a need to measure the corresponding effects. One way to measure these undergroun...

Mathematical models of petroleum reservoirs have been utilized since the late 1800s. A mathematical model consists of a set of equations that describe the flow of fluids in a petroleum reservoir, together with an appropriate set of boundary and/or initial conditions. This chapter is devoted to the development of such a model. Fluid motion in a petroleum reservoir is governed by the conservation...

Reservoir characterization and asset management require comprehensive information about formation fluids. In fact, it is not possible to find accurate solutions to many petroleum engineering problems without having accurate pressure-volume-temperature (PVT) data. Traditionally, fluid information has been obtained by capturing samples and then by measuring the PVT properties in a laboratory. In ...

The p-Laplacian Δpv ∇ · |∇v|p−2∇v arises from a variety of physical phenomena such as non-Newtonian fluids, reaction-diffusion problems, flow through porous media, nonlinear elasticity, glaciology, and petroleum extraction cf. Dı́az 1 . It is important to study the qualitative behavior e.g., oscillatory behavior of solutions of p-Laplace equations with superlinear terms and forcing terms. Forced...

Quantitative information regarding the endmember composition of the gas and oil that flowed from the Macondo well during the Deepwater Horizon oil spill is essential for determining the oil flow rate, total oil volume released, and trajectories and fates of hydrocarbon components in the marine environment. Using isobaric gas-tight samplers, we collected discrete samples directly above the Macon...

Summary Our objective is to present selected rheological and mechanical properties of rock-based geopolymers contaminated with different concentrations drilling fluids. The possible flash setting the maximum intake fluids before seeing a dramatic deterioration are presented. Rock-based designed for cementing conductor surface casing were prepared cured up 28 days at 22°C atmospheric pressure. W...
