On the Compaction and Viscous Behavior of Deep-Water Reservoirs
There have been many studies on reservoir compaction where different mechanisms being suggested as the reasons behind the integrity of unconsolidated reservoirs during production. Theory of poroelasticity is often used to evaluate the likelihood of compaction under these circumstances, but it is often failed to explain the creep behavior of unconsolidated formations. In this study, attempts are...
متن کاملGalactic Fountains as Magnetic Pumps
We study a simple, kinematical model of a galactic fountain ow and show that a horizontal eld in the galactic plane can be pumped into the halo to a height of several kiloparsecs. This pumping eeect results from the topological structure of the ow in which the updraughts (represented by hot gas) form a connected network, whereas the downdraughts (associated with isolated cool clouds) are discon...
متن کاملFountains, histograms, and q-identities
Merlini and Sprugnoli [6] discuss fountains and histograms; for the reader’s convenience, we review a few key issues here. A fountain with n coins is an arrangement of n coins in rows such that each coin in a higher row touches exactly two coins in the next lower row. A p-histogram is a sequence of columns in which the height of the ( j +1)st column is at most k + p, if k is the height of colum...
متن کاملMicrobiological contamination of water in fountains located in the city of Toruń, Poland.
OBJECTIVE The aim of this study was determination of the level of water contamination in fountains in Toruń, Poland. METHODS The studies were conducted at monthly intervals from May - September 2009, and consisted in the determination of the number of heterotrophic bacteria capable of growing at a temperature of 22 and 37°C (PN-ISO 6222), as well as the number of coliform bacteria (PN-75/C-04...
متن کاملAn Investigation into the Deep Drawing of Fiber-Metal Laminates based on Glass Fiber Reinforced Polypropylene
Abstract Fiber-metal laminates (FMLs) are new type of composite materials which could improve defects of traditional composites in ductility, formability, impact and damage tolerance. Drawing behavior of a thermoplastic based FML was investigated consisting of glass-fiber reinforced polypropylene composite laminate and aluminum AA1200-O as the core and skin layers, respectively. The effects o...
