The angiosperm fossil record suggests that these plants underwent a rapid diversification from the Barremian of the Early Cretaceous (c.
The primary target, Murombe, a Barremian Age turbidite fan system and a secondary target, the Baobab, a shallower Santonian Age structure were both penetrated.
Reservoir at the Barremian and Valanginian A levels are interpreted to be deep water turbidite sandstones.
Foraminiferally defined biostratigraphic episodes and sedimentary pattern of the Cretaceous drift succession (Early Barremian to Late Maastrichtian) in seven basins on the South African and southern Namibian continental margin.
One group dates from an early part of the period, the Barremian, and the other is from tens of millions of years later.
A problem, however, is the current dearth of reliable dates from the Middle Jurassic Oxfordian Stage to the Early Cretaceous Barremian Stage, a span of some 35 million years.
However, it is only within the last few years that new descriptions of Cretaceous amber spiders have been published, for example in fossil resins of Turonian age from New Jersey (Penney 2002, 2004a), Barremian age from the Isle of Wight (Selden 2002), Upper Neocomian-basal Lower Aptian age from Lebanon (Penney & Selden 2002; Penney 2003a; Wunderlich & Milki 2004 [not 2001 as cited by Poinar & Milki 2001]), Albian age from Myanmar (Penney 2003b, 2004b) and Campanian age from Canada (Penney 2004c).
The Barremian to Aptian Chaswood Formation is characterized by the alternation of clay and sand units.
The "drowning" of the mega-bank occurred earlier in the northern part of the Blake Plateau/Grand Banks (in Barremian time, about 115 million years ago) than the southern part (late Albian, about 100 million years ago).
In addition, two thin intervals of carbonate reservoirs with indications of hydrocarbons were found in the Aptian and Barremian sections, confirming an active petrolific system.
Primary focus has been on the Cretaceous clastic section where stratigraphic traps have been identified in three reservoirs: Barremian, Valanginian A and Valanginian B
5% when they meet the full cost of drilling and testing the exploration well to the Barremian level.
