Hydrocarbon trapping mechanism and petrophysical analysis of Afam field, offshore Nigeria

The structural trapping mechanism and petrophysical attributes of Afam field, offshore Niger Delta was evaluated using 3D seismic reflection data and composite well logs data. The structure maps and seismic sections show that the anticlinal structure at the centre of the field, which is tied to the crest of the rollover structure assisted by faults, is the principal structure responsible for the hydrocarbon entrapment...

Development of an approach for mapping of features thermal and hydric of watersheds: Case of the watershed of Brezina (Northwest of Algeria)

The objective of the present study is to present the parameters of the hydrological assessment of a steppe area from the data of remote sensing. ¶Adopted methodology rests on the cartography of the various parameters of the hydrous and energy balance on one year scale. ¶Several methods are used. ¶Thus, for cartography of precipitations, one uses in a combined way the relief, the distance of the sea and...
