Africa (Sub-Sahara) Oranto Petroleum has signed two production-sharing agreements (PSAs) with Uganda for oil and gas exploration around Lake Albert, the Nigerian company said. The deal covers the Ngassa Shallow and Ngassa Deep plays in blocks near the southern part of Lake Albert, according to the Uganda Ministry of Energy and Mineral Development. The pacts closely followed the signing of a PSA by Australia's Armour Energy that covers the Kanywataba block, a 133-square-mile area that was relinquished by three international companies in 2012 after failed exploration attempts. The agreements with Oranto and Armour involve acreage that was offered in Uganda's first competitive exploration licensing round last year. Uganda discovered oil in 2006 in the Albertine rift basin along the Democratic Republic of Congo border.
Investigation of turbulence dynamics is very important for the understanding of dispersion and transport of pollutants in the marine environment. Specifically, at the surface boundary layer, dispersion phenomena are governed by the interaction of different forces (i.e., currents, waves, and winds) and are characterized by a wide range of temporal and spatial scales (Gallerano et al., 2016). Estimates of turbulence parameters able to describe the interaction of these different forces are required for an accurate prediction of pollutant pathways and concentrations. At present, turbulent dispersion simulations are mainly carried out by using Lagrangian particle models, alternatively based on a Wiener process or a Langevin scheme, which require as input data such turbulence parameters as diffusivity, velocity variance, and Lagrangian time scale (Monti and Leuzzi, 2010; De Dominicis et al., 2012). Besides, a new efficient approach is represented by kinematic chaotic models (Lacorata et al., 2014; Lacorata and Vulpiani, 2017).
The oil and gas sector is a topic of the utmost importance nowadays, as its business turnover moves several billion euro every year. Moreover this sector is strategic both globally and nationally. This study is realized by “Bicocca” University of Milan supporting the Directorate General for Mineral and Energy Resources of the Italian Ministry of Economic Development in application of the Legislative Decree April 3rd, 2006 n0152 as modified by the art. 35 of the Legislative Decree June 22nd, 2012 n0.83 about the offshore safety in accordance to the objective of improvement knowledge about the geology of offshore area. Within this aim this paper shows the new offshore exploration and production (E&P) perspectives for what is concerning Italian continental shelf (as defined by the UNCLOS,1982 ), based on the examination of national data.
With the Ministerial Decree of August 19th 2013, all areas open to hydrocarbon E&P activities were rescheduled and a new area called “Zone E” was opened in the west side of the Sardinian offshore. With the new interest for the deep offshore and for reservoirs with complex geology there is need for the improvement in knowledge about the geological and tectono-stratigraphic settings as well as in definition of the potentiality of the area, through the assessment of the presence of petroleum system’s characteristic elements. The goal of this study is to review existing literature, collect and preliminary process data about the area and give an overview of the potential presence of "undiscovered” resources of hydrocarbon in the west Sardinian offshore.

While attempting to relate the theme of this year's Conference to my presentation - it occurred to me that the metaphor "Winds of Change" unfortunately didn't come close to describing the magnitude of the events that have taken place in Eastern Europe and the Soviet Union.
Perhaps use of greater natural phenomena might be more appropriate Perhaps use of greater natural phenomena might be more appropriate in this case - say - Hurricanes of Change" or possibly "Earthquakes of Change."
Or - how about the ultimate? - the "Mother of All Changes"!
Whatever forces have been at work in this part of the world - they have laid waste to a political system many late was impervious to the effects of internal dissent.
And Chevron has been right in the thick of it!
And we're still hanging on for dear life!
Occasionally - I have to remind myself that our negotiations with the Soviets predate the political transformation of Eastern Europe and the USSR.
Chevron signed a general trade agreement with the Soviets in March of 1989 - several months before the transcendent events of that fall.
And we have been trying to get this venture off the ground ever since!
As you might well imagine - the negotiating trail has taken many twists and turns since we began the process.
With each new political development - it seems we've had to renegotiate certain -- previously agreed-upon -- provisions of the joint venture.
Now - with the August coup having failed - the Soviet republics are pressing their advantage. pressing their advantage. The Republic of Khazakhstan - where the joint venture is located - is in the forefront of the movement by the republics to extricate themselves from Soviet central government control.
This is not necessarily an advantageous development in Chevron's view.
We anticipate that the final stages of our negotiations will now become more complicated - due to uncertainties that have arisen as a result of the latest political developments.
But - I digress.
The purpose of my talk today was not to focus on Chevron's experience - but to offer our view of the potential for additional business opportunities in the oil and gas industry.
PETROLEUM POTENTIAL OF DEEP-WATER AREAS OF THE MEDITERRANEAN AND CARIBBEAN SEAS Abstract The approach to the petroleum potential of deep-sea areas of the Mediterranean and Carribean Seas is made through discussion of the general tectonic history of these areas, the geology of their margins and the hydrocarbon fields and shows already found. Many parts of the deep-sea areas in question appear to be previously emerged or shallow-water regions foun- dered in Tertiary times which should therefore have similar a priori petroleum potential to any other com- parable conventional prospective area. Thickness and type of Sediments, widespread salt layers and their halokinesis, deep-sea deltaic fans, scarps and trenches are also discussed. Résumé Le potentiel pétrolier des zones profondes de la Méditerranée et des Caraïbes, est abordé par l'étude de l'histoire tectonique de ces régions, la géologie de leurs marges et les champs et indices d'hydrocarbures déjà découverts. Une bonne partie des zones profondes en question semble être des zones anciennement émergées ou peu profondes, ayant été effondrées au Tertiaire. Ces régions présentent donc un intérêt pétrolier sem- blable à celui de prospects classiques comparables. Les problèmes pétroliers, sont aussi liés aux particu- larités suivantes : épaisseur et nature des sédiments ; couches de sel et leur halocinèse; deltas profonds; escarpements et fossés. 1. INTRQDUCTION The link between the Mediterranean and the Carib- bean Seas is that they must have both been a part of the Tethys hiatus which originated in Upper Car- boniferous times ; they are both : (a) inserted between two continental blocks- Eurasia and Africa for the Mediterranean Sea, North and South America for the Caribbean Sea; (b) bounded by orogenic belts ; and (c) similar in their Tertiary evolution. But it is also well known that today's Mediterranean and Caribbean Seas have little to do with the more or less equatorial Mesozoic and early Tertiary Tethys. They actually correspond to late Tertiary pull-apart and primarily foundered areas, partly superimposed to bordering tectonic units, partly as collapsed inner sides or subsiding foredreps of orogenic arcs. ' It is essentially the recognition of the importance of vertical movement as opposed to the Atlantic type of ocean opening that will govern our approach to the by R. S. BYRAMJEE, J. F. MUGNIOT, Compagnie Française du Pétroles, France, and B. BIJU-DUVAL, Institut Français des Pétroles, France petroleum potential of the deep-water areas of the Mediterranean and Caribbean Seas. 2. THE DEEP MEDITERRANEAN BASINS The Mediterranean Sea has a surface area of 2.5 million km2, 1.4 million of which being areas where the water depth exceeds 1000 m; the 2000 m water depth contour covers about 1 million km2. This is to say that the deep and very deep water area covers about 60% of the Mediterranean Sea. The area of water depth greater than 200 m corresponds to
