Hydrocarbon exploration and reservoir analysis

Detailed descriptions of Kimmeridgian to Late Barremian palynofloras are presented from the Malha-1 well, north Sinai, Egypt. The Jurassic Masajid Formation and the Early Cretaceous Mersa Matruh Shales have yielded about 100 species of miospores and microplankton. Four palynozones are defined, based on the analysis of the stratigraphie distribution of dinocysts, spores and pollen. The Masajid Formation includes the PS4 palynozone, which is dated as Kimmeridgian. The overlying Mersa Matruh Shale is divided into three zones, ranging in age from Berriasian -Early Hauterivian (PS3), Late Hauterivian - Early Barremian (PS2) to Late Barremian (PS1). Comparison of the assemblages suffers from the lack of data, but in general the Egyptian microfloras are less diverse and poorer than those known from north-western Europe. The assemblages are similar to those described from the Jurassic-Cretaceous deposits elsewhere in the circum-Mediterranean region.
