The study addresses the hydrocarbon prospectivity of offshore Gabon with a particular focus on the South Gabon Basin based on detailed 3D PGS/DGH MegaSurvey seismic and well data interpretation. It describes the geology, structure and hydrocarbon potential of the South Gabon Basin. The Gabon Basin consists of three sub-basins; the North Gabon, South Gabon and the Interior Basin. It is located within the larger Aptian Salt Basin of equatorial West Africa that stretches from southern Cameroon to Angola. Both the North and South Gabon basins have been found to be potentially prospective during this study. The pre-salt section is structurally complicated as compared to the post-salt section and it has been difficult to image seismically. Numerous structural and stratigraphic traps have been identified and evaluated. Fan/channel systems have been mapped in both pre- and post- salt sections. Within the deeper pre-salt section, tilted fault blocks containing high amplitudes have been mapped suggesting potential sand presence and possible DHIs. Post salt sediments are dominated by 4-way dip closures and stratigraphic trapping mechanisms. Copyright © (2012) by the European Association of Geoscientists & Engineers All rights reserved.

This paper outlines examples of near surface fluid and gas flow features observed in the seismic interpretation of the Gabon MegaSurvey. Features range from lone craters on the seabed to clusters of pockmarks that appear to have random distribution patterns and other clusters that have a clearly defined linear or channel-like trend. A description of the various pockmark features are given with possible explanations of their formation. The significance of pockmarks is described in the potential for hydrocarbon reserves and the importance of mapping them for sea floor hazards. Numerous amplitude anomalies are associated with these pockmarks as observed in the seismic data. These amplitude anomalies are potential hydrocarbon indicators which afford shallow drilling opportunities and reserves. Pockmarks also help to identify areas of seabed hazards for oil field operations. There is significant value in these pockmarks both in hydrocarbon reserves and oil field safety. © 2010, European Association of Geoscientists and Engineers.

This paper outlines examples of potential new reservoir channel and canyon features observed in the interpretation for the Gabon MegaSurvey. The canyons occur at the Base Miocene Unconformity and the channels are imaged at the Ozouri formation and offer exciting new exploration opportunities. Their relevance and origins are discussed with respect to the regional geology. The interpretation describes the various methods used to image these canyons and channels. Methods, that can be incorporated into a workflow that will define a potential prospect to drill. The well developed canyon and channel systems identified in the Gabon offshore area is a potential new reservoir target similar to prospects targeted in the Niger and Congo deltas. © 2010, European Association of Geoscientists and Engineers.

Årets resultat for Brødrene A & O Johansen A/S er på DKK 105.403 tkr. I henhold til vedtægternes § 3, stk. 10,    jf. § 18, stk. 2, har præferenceaktiekapitalen ret til forlods kumulativt årligt udbytte på 6 %. Herefter fastsættes tilsvarende procentvise udbytte til stamaktiekapitalen, og såfremt der fastsættes yderligere udbytte, er stamaktiekapitalen og præferenceaktiekapitalen berettigede til at modtage samme procentvise udbytte. Bestyrelsen foreslår, at der udbetales et udbytte på i alt DKK 60 pr. DKK 100 aktie, svarende til 6 % pr. år for de ni (9) år, hvor der ikke har været udbetalt udbytte, samt 6 % for regnskabsåret 2016. Udbytte udbetales derfor på såvel præferenceaktier som stamaktier. Bestyrelsen har i fortsættelse af forslaget til hensigt at gennemføre et aktiesplit i forholdet 1:10, således at præferenceaktionærerne for hver én (1) præferenceaktie a nominelt DKK 100 modtager ti (10) nye præferenceaktier a nominelt DKK 10. Selskabet tilbagekøbte (i) nominelt DKK 22.300.500 præferenceaktier fra Sanistål A/S den 21. marts 2016 og (ii) nominelt DKK 7.135.100 præferenceaktier fra J-F. Lemvigh-Müller Holding A/S den 6. januar 2017. Ud af det samlede tilbagekøb af nominelt DKK 29.435.600 foreslår bestyrelsen således at annullere nominelt DKK 29.000.000. Om tilbagekøbskurserne kan oplyses følgende: Bestyrelsen foreslår, at generalforsamlingen på sædvanlig vis bemyndiger bestyrelsen til i tiden indtil 1. maj 2018 at lade selskabet erhverve egne præferenceaktier op til en pålydende værdi af i alt 10 % af selskabets aktiekapital på bemyndigelsestidspunktet, og således at den til enhver tid værende beholdning ikke må overstige de nævnte 10 %. Vederlaget må ikke afvige fra den på erhvervelsestidspunktet på Nasdaq Copenhagen noterede officielle kurs med mere end 10 %.

Female moths produce a sex pheromone, a different blend of chemicals for each species, which attracts males from a distance. Males detect these chemicals with exquisitely sensitive hair-like structures in the antenna. These hairs contain specialized neurons, nerve cells that express pheromone receptors which are activated when they bind to individual pheromone components. Different species have different pheromone receptors, and so the ability to most accurately smell females of the same species prevents attraction to other females. Solving the puzzle of why a certain pheromone receptor is activated only by a specific chemical has motivated much past research. "Our previous work in mapping the pheromone receptors of the European Corn Borer convinced us that this species doesn't fit the mold, and so we took another approach," says lead author Fotini Koutroumpa. The European Corn Borer uses a simple pheromone with only two isomeric compounds, identical except for the orientation of a double bond. The two "pheromone strains" of this species produce them in different proportions. E-strain females make mostly the E isomer with traces of the Z isomer, which is highly attractive to E-strain males. Z-strain females release the opposite ratio, attracting Z-strain males. In both cases, both components are absolutely necessary for attraction, and males of both strains can smell both, with similar or identical antennal structures and pheromone receptors. So what difference among the E and Z males could explain their opposite preferences? "We decided to look for a difference at the genetic level", says co-author Astrid Groot. By crossing the E and Z strains in the laboratory and mapping the gene governing male preference, the researchers found that the pheromone receptors had little or no effect. Instead, a chromosomal region containing genes involved in neuronal development explained most of the male behavioral response. "This result fits with our previous work showing that E and Z males have different connections between the brain and the neurons containing pheromone receptors," explains co-author Teun Dekker. This suggests that females of the E or Z strain smell the same to both E and Z males, while their preferences are controlled not by their noses but instead by their brains. "This result will point future research towards the tiny but complex moth brain, and shed light on how the diverse pheromone systems of the thousands of moth species has changed throughout evolution," concludes co-author David Heckel. [DGH] The findings were published in the Proceedings of the National Academy of Sciences.
