The Potentiality of Source Rocks in Hayat Oilfield Based on Well Data, North Western Desert, Egypt

Abstract

A total of 51 ditch samples were collected from organic rich horizon including dark-grey shales and limestones of the two wells (Hayat Deep-20x: 32 samples; Hayat-1x: 19 samples) and analyzed by a Leco WR 12 apparatus and Rock Eval pyrolysis. These samples were used as evaluation in potential source rocks in the Hayat oilfield. The results showed the three significant source rock intervals, which were penetrated by the Hayat deep-20x and Hayat-1x: wells. (1) The Upper Cretaceous source interval does not have the capacity to generate significant quantities of hydrocarbons in Hayat Deep-20x well and have fair to good organic richness in Hayat-1x well. (2) The Lower Cretaceous source interval ranges from a poor to good source potential and enters to the early stage of hydrocarbon generation. (3) The Middle Jurassic source interval has good source potential and has the capacity to generate significant quantities of gas generation.
