This document summarizes a poster presentation about delineating the Upper Jurassic reservoirs in the Witch Ground Graben region of the North Sea using genetic sequence stratigraphy methodology. The study applied this methodology to over 100 wells in the area around the Scott Field, identifying up to twelve regionally correlatable maximum flooding surfaces that constrained five sandstone intervals. Mapping these intervals revealed shifts in the basin's depositional center and effects of syndepositional faulting. The results enhanced understanding of the tectonics, sedimentation, and basin evolution in this economically significant area.
TURBIDITES: MODE OF FORMATION OF TURBIDITES AND ITS ECONOMIC IMPORTANCEJames Opemipo OLOMO
Turbidites are deposits resulting from turbidity currents. They are gravity driven sediments derived mostly from the continents and are deposited on the ocean floor when the transporting medium loses its energy. These turbidite deposits are sealed most times by shales to form a stratigraphic trap. If the factors required for hydrocarbon accumulation in a petroleum play system are prevalent, then the turbidite will most likely serve as a good reservoir to house hydrocarbon. Our modern day economy requires enormous amount of energy to meet the energy demand and hydrocarbon unarguably is a non-renewable resource. Perhaps its worth mentioning that the decrease in reserves. And it has been established that turbiditic deposits help to host important economic resources such as hydrocarbon, when the right conditions are emplaced. Hence, the need to understand their formation for exploration success.

Delineation of Hydrocarbon Bearing Reservoirs from Surface Seismic and Well L...IOSR Journals
Hydrocarbon reservoir has been delineated and their boundaries mapped using direct indicators from 3-D seismic and well log data from an oil field in Nembe creek, Niger Delta region. Well log signatures were employed to identify hydrocarbon bearing sands. Well to seismic correlation revealed that these reservoirs tied with direct hydrocarbon indicators on the seismic section. The results of the interpreted well logs revealed that the hydrocarbon interval in the area occurs between 6450ft to 6533ft for well A, 6449ft to 6537ft for well B and 6629ft to 6704ft for well C; which were delineated using the resistivity, water saturation and gamma ray logs. Cross plot analysis was carried out to validate the sensitivity of the rock attributes to reservoir saturation condition. Analysis of the extracted seismic attribute slices revealed HD5000 as hydrocarbon bearing reservoir.
sedimentary basin may be defined as an area of depression in the earth’s crust in which sediments accumulate during a particular time span at a significantly greater rate, and so to a significantly greater thickness.

The Tuktoyaktuk Peninsula is located in the Beaufort - Mackenzie Basin Area of Canada and has seen numerous oil and gas discoveries. An orientation survey using multiple geochemical methods demonstrates that oil and gas seeps occur over these reservoirs, are detectable through thick permafrost, and these methods can be used as a regional exploration tool.

Acordionero Oil Field Discovery, Middle Magdalena Basin, Colombia: An Unusual...Mario Prince
Oil exploration of Cenozoic clastic reservoirs in northern Middle Magdalena Basin has been predominantly focused on faulted anticline-type structural plays rather than more subtle stratigraphic or combination traps. The Acordionero field is a recent oil discovery found within an unusual structural -stratigraphic configuration, defined only after 3D and 2D seismic reprocessing benefitting from well results.
Based on a trap outline originally mapped with 2D seismic lines, the Acordionero-1 well was located and drilled in 2013 between two 1960s abandoned dry wells. The true trap configuration delineated by reprocessed seismic data was confirmed by follow-up 2014 drilling. In order to understand the field, multidisciplinary studies were conducted including detailed geology study of the Lisama Formation using outcrop and core data, reprocessing and interpretation of seismic data with constraining geological input, detailed log analysis and exhaustive reservoir examination from test and flow data.
The field is an important accumulation in the Paleocene sandstones of the Lisama Formation and has estimated original oil in place of more than 300 million barrels. Remarkably, the oil gravity for the field ranges from 13.5 to 25º API. The production rates are also atypical for the basin; the initial test for the well Acordionero 1 produced over 3200 BOPD in natural flow. This case history perfectly illustrates the concept of holistic approach to petroleum exploration that includes geology, geophysics and engineering contributions in all phases of the project (Enachescu, 2015). This integrated process is extended to field reservoir evaluation and design of production rate and optimum recovery plan.

Abstract
In 1986, the State of California posted a fish consumption advisory for Clearlake, a large,
freshwater lake located 80 miles north of San Francisco, because of mercury contamination. The
abandoned Sulphur Bank Mercury Mine on the eastern shore of Clearlake is the suspected source of
the mercury. Herman Impoundment, the now flooded open pit of the Sulphur Bank Mercury Mine, is
separated from Clearlake by a dam composed of waste rock removed from the open pit. Hydrological
and geochemical studies indicated that water is flowing from the open pit through the waste rock
dam into Clearlake. However, an accurate map of flow pathways through the waste rock dam was
needed for planning groundwater flow intervention. Results from an airborne EM conductivity survey
flown over the mine site and adjacent areas suggest the probable flow paths taken by the highly
conductive Herman Impoundment water through the waste rock dam. The airborne data were then used
to target areas for ground-based EM conductivity surveys with a Geonics EM34-3XL instrument. The
higher-resolution results of the ground-based survey corroborated the findings of the airborne
survey. This information will allow groundwater-flow intervention efforts to be concentrated within
small areas of the waste rock
dam.

The Earth is an unusual planet by having bimodal topography that reflects the two distinct types of crust.
Crust is outer part of the Earth and compositionally is consist tow types, continental and oceanic crust.
The oceanic crust is thin (~ 7 km ), and composed from denser rocks such as basalt , younger.
Whereas the continental crust is thick (~ 40 Km), and composed of highly diverse lithologies, and contains the oldest rocks.
Wading birds have declined across Europe as the intensification of lowland agriculture has caused severe habitat destruction and degradation. Aggregates extraction sites present areas of exposed fine sediments deposited as waste material in silt lagoons which could recreate lost wader habitat. This project explores the value of silt lagoons for wading birds by investigating sediment composition, invertebrate food availability and monitoring bird activity at Wykeham quarry.
This project won the 3rd Prize in the International Quarry Life Award in 2012 and the 1st Prize in National Quarry Life Award in 2012 in the United Kingdom.
