These vessels are mostly to tow and anchor up oil rigs. They are supplied with winches for towing and anchor handling and have an open stern to allow the decking of anchors. An anchor-handling supply vessel is a combined supply and anchor-handling ship that carry supplies to platforms and drilling rigs
The concept of the “anchor user” is taken from the gas pipeline industry. Such as a gas consumer that consumes sufficient quantities of gas to represent a required entry threshold to justify the high infrastructure investment required by a new gas supplier to enter the market place. In Israel, IEC has been the only anchor consumer for natural gas producers. The FERC has recently adopted the concept to the electricity sector to promote investment in new electricity transmission lines in the US, by allowing developers to allocate half the line’s capacity to representatives of “anchor users” for 25 years, before running any open season or auction that opens up capacity to others. The concept is intended to provide early commitments that facilitate financing of the investment. > >
Such as in analogous features within two different reservoirs
Territory that could be owned by another lessee and which is of the same or similar geological formation. Often information from a producing analogous reservoir or territory may also be used to conduct the analysis on the field in question
An analogous reservoir is one in the same geographic area that is formed by the same, or very similar, geological processes as a reservoir in question in so far as sedimentation, diagenesis, pressure, temperature, chemical and mechanical history and structure are concerned. It also has the same or similar geologic age, geologic features, and reservoir rock and fluid properties. Analogous features and characteristics can include approximate depth, pressure, temperature, reservoir drive mechanism, original fluid content, oil gravity, reservoir size, gross thickness, net-to-gross ratio, lithology, heterogeneity, porosity and permeability
An environment in which free oxygen is lacking or absent. Pertaining to systems, reactions or life processes of species, such as bacteria, in which atmospheric oxygen is not present or not required for survival
AVO analysis is a technique by which geophysicists attempt to determine thickness, porosity, density, velocity, lithology and fluid content of rocks. By doing ”Amplitude Versus Offset” evaluations on the raw unstacked seismic data it is possible to get a much better understanding of what the amplitude anomalies are telling
An abrupt increase in seismic amplitude that can indicate the presence of hydrocarbons, although such anomalies can also result from processing or other problems
Unit to measure electricity current
