DL Abstract

 

The results of regional deep seismic acquisition in the South Atlantic continental margins have shed new lights on the birth and development of sedimentary basins formed during the Gondwana breakup. Recent models of mantle exhumation as observed in the deep water Iberian margin have been applied extensively to the interpretation of several basins in the Eastern Brazilian and West African conjugate margins. However, the tectonic development of these basins is markedly different from the magma-poor margins, and in this lecture we emphasize the contrasts from the tectono-sedimentary features imaged in deep-penetrating seismic profiles that extend from the platform towards the oceanic crust, which indicate that the Red Sea constitutes a better analogue for the birth of divergent continental margins.

In international exploration, the new normal is starting to look like the old normal. And 2014 looked a lot like the year before.

Angola’s oil industry continues to benefit from new oil discoveries and ever increasing oil production, according to a paper presented at the Deepwater Offshore West Africa Conference (DOWAC) by AAPG member, Tako Koning.

The impact of the rapid economic growth of “Asian giants” China and India is such that African oil supplies now face increased demand to fuel this growth and, therefore, increased E&P activity.

Explorer Historical Highlight

 

The relatively recent, very large discoveries offshore Brazil have put pre-salt exploration in the South Atlantic back in the foreground. Pre-salt exploration history, however, is far more ancient and marked with some major successes – but also many failures. Here’s a brief overview of this exploration in West Africa until the M’Boundi discovery, which will be described in detail as it brings some lessons that readers can discover for themselves.

This field trip to the Cambrian microbial facies in the Mason, Texas, area will highlight several aspects of microbialite reservoirs including their composition, size and geometry. The Mason, Texas, outcrops afford spectacular views of both cross-section and plan views of microbialite facies, offering an opportunity for a truly 3-D view of the architecture of these potential reservoirs.

The field trip will include stops at Shumard Canyon and Bone Canyon to observe the scale and internal architecture of submarine channels incising the bedrock of the relict platform. Other field-trip stops will include Stratotype Canyon, Black Stove Canyon, and Rest Area Gully to observe basin-restricted carbonate and siliclcastic sediment gravity flow deposits, carbonate channel-levee complexes, failure scours associated with the downslope transport of olistostromal blocks, and thick (>50 m) accumulations of recumbently folded deposits associated with these failure events.
