Seismic Reflection Methods in Offshore Groundwater Research

Marine geophysical methods, in particular seismic reflection data, can help characterize offshore hydrogeological systems and yet the existing global database of industrial basin wide surveys remains untapped in this context. In this paper we highlight the importance of these data in groundwater exploration, by reviewing existing studies that apply physical stratigraphy and morpho-structural interpretation techniques to provide important information on—reservoir (aquifer) properties and architecture, permeability barriers, paleo-continental environments, sea-level changes and shift of coastal facies through time and conduits for water flow. We then evaluate the scientific and applied relevance of such methodology within a holistic workflow for offshore groundwater research. Keywords: submarine groundwater; continental margins; offshore water resources; seismic reflection 1. -

Integration of Seismic and Petrophysics to Characterize Reservoirs in ‘‘ALA’’ Oil Field, Niger Delta

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. In the exploration and production business, by far the largest component of geophysical spending is driven by the need to characterize (potential) reservoirs. The simple reason is that better reservoir characterization means higher success rates and fewer wells for reservoir exploitation. In this research work, seismic and well log data were integrated in characterizing the reservoirs on “ALA” field in Niger Delta. Three-dimensional seismic data was used to identify the faults and map the horizons. Petrophysical parameters and time-depth structure maps were obtained. Seismic attributes was also employed in characterizing the reservoirs. Seven hydrocarbon-bearing reservoirs with thickness ranging from 9.9 to 71.6 m were delineated. Structural maps of horizons in six wells containing hydrocarbon-bearing zones with tops and bottoms at range of −2,453 to −3,950 m were generated; this portrayed the trapping mechanism to be mainly fault-assisted anticlinal closures. -

Introduction to Alkenes and Alkynes in an Alkane, All Covalent Bonds
Introduction to Alkenes and Alkynes In an alkane, all covalent bonds between carbon were σ (σ bonds are defined as bonds where the electron density is symmetric about the internuclear axis) In an alkene, however, only three σ bonds are formed from the alkene carbon -the carbon thus adopts an sp2 hybridization Ethene (common name ethylene) has a molecular formula of CH2CH2 Each carbon is sp2 hybridized with a σ bond to two hydrogens and the other carbon Hybridized orbital allows stronger bonds due to more overlap H H C C H H Structure of Ethylene In addition to the σ framework of ethylene, each carbon has an atomic p orbital not used in hybridization The two p orbitals (each with one electron) overlap to form a π bond (p bonds are not symmetric about the internuclear axis) π bonds are not as strong as σ bonds (in ethylene, the σ bond is ~90 Kcal/mol and the π bond is ~66 Kcal/mol) Thus while σ bonds are stable and very few reactions occur with C-C bonds, π bonds are much more reactive and many reactions occur with C=C π bonds Nomenclature of Alkenes August Wilhelm Hofmann’s attempt for systematic hydrocarbon nomenclature (1866) Attempted to use a systematic name by naming all possible structures with 4 carbons Quartane a alkane C4H10 Quartyl C4H9 Quartene e alkene C4H8 Quartenyl C4H7 Quartine i alkine → alkyne C4H6 Quartinyl C4H5 Quartone o C4H4 Quartonyl C4H3 Quartune u C4H2 Quartunyl C4H1 Wanted to use Quart from the Latin for 4 – this method was not embraced and BUT has remained Used English order of vowels, however, to name the groups -

Prevention policies and control measures that may explain changes were surveyed. The aim was to evaluate how the application of of Occupational Health and Safety Assessment Series OHSAS 18001.04 principles as well as Environmental protection Agency EPA and European Oil Company Organisation for Environment, Health and Safety CONCAWE practices have influenced air concentrations. Benzene air concentrations declined in 11 of 17 units, six of which were associated with declining exposures. Benzene air concentrations declined across all units on average by 46%. This amounts to an average yearly decline of 1.7%. TPH air concentrations declined in 10 of 17 units, seven of which were associated with declining exposures. The average decline in TPH air concentrations was 49%, corresponding to 1.3% per year. As a result, average working day exposure in 10 of 17 units have declined significantly and today, benzene and TPH exposure in most units are well below 10% of the current Occupational Exposure Limit (OEL8h:s). -
An Arctic Engineer's Story 1971 to 2006
An Arctic Engineer’s Story 1971 to 2006 by Dan Masterson To my wife Ginny and my sons, Andrew, Greg, and Mark ii Preface In 1971, I just happened to be in the right place at the right time. I had just completed my PhD and was looking for work. I was told to contact Hans Kivisild who had just been given a contract from an oil company to investigate an engineering issue in the Arctic. This started my career in Arctic engineering, just when the second major exploration phase was beginning in the western Arctic, 123 years after Franklin started the first phase of exploration in the area. This recent phase was also filled with individuals who were going “where few had gone before,” but unlike the earlier explorers, these recent explorers were accompanied by regulators, scientists and engineers who wanted to ensure that the environment was protected and also to ensure that the operations were carried out in the safest and most cost- efficient manner. Between about 1970 to 1995, several oil companies and Arctic consulting companies turned Calgary into a world leader in Arctic technology. It was a time that one could have an idea, check it out in small scale, and within a year or so, use it in a full-scale operation. During the next 25 years, industry drilled many wells in the Arctic using the technologies described in this book. In 1995, the oil industry pulled out of the Arctic mainly due to lack of government incentives and poor drilling results. In 2016, both the Canadian and United States governments declared a moratorium on Arctic drilling. -

Trace the boom-and-bust cycle of oil and gas during the 1920s and 1930s. With the discovery of oil at Spindletop, thousands of fortune seekers flooded into Texas, turning small towns into overcrowded cities almost overnight. An oil worker’s wife described life in East Texas in 1931. There were people living in tents with children. There were a lot of them that had these great big old cardboard boxes draped around trees, living under the trees. And any- and everywhere in the world they could live, they lived. Some were just living in their cars, and a truck if they had a truck. And I tell you, that was bad. Just no place to stay whatsoever. Mary Rogers, interview in Life in the Oil Fields Oil, Oil Everywhere The oil boom of the 1920s and 1930s caused sudden, tremendous growth in Texas.
