Abstract |
: |
The primary marketable petroleum flows from the Eromanga Basin was gas formed from Namur-1 in 1976 (Cooper area) Trough. Meanwhile, 1959 over 2000 boreholes have entered the Eromanga Basin succession and over hundred thousand kilometers of seismic has been developed. Discoveries have focused in the Cooper province. Greatest novel applicant surveyors are now directing Eromanga Basin hydrocarbons plays. Vertical passage of petroleum from Permian source rocks was extensively acknowledged as the main source of greatest Eromanga-reservoir petroleum (in the Cooper area). Both Cooper and Eromanga mature source rocks have donated to hydrocarbon accumulations in the area. Sideways passage from these source regions has also been assumed. The Poolowanna and Birkhead formations comprise organic-rich shales that are oil-prone and in places at top maturity for oil generation. Somewhere else in the basin, the occurrence of thick Poolowanna, Birkhead and Murta formations is acute to estimation of oil source possibility. Principal reservoirs in the Cooper Area are the braided fluvial Hutton and Namur sandstones (porosities up to 25%, permeability up to 2500 md). Caps involve of intra-formational siltstones and shales of the Birkhead and Murta formations in the Cooper Area. In the Poolowanna Trough, they comprise of intra-formational siltstone of the Cadna-owie Fm. Elsewhere in the basin, potential caps contain the Cadna-owie Fm. Trapping mechanisms inside the Eromanga Basin are commonly structural (arches with four-way dip closure or drapes over pre-existing highs) with a stratigraphic element (e.g. Hutton and Namur formations).
The target of this work is the delineation of new leads and prospects in the study area of the Eromanga Basin through an integration of the logs, seismic and geologic data and establishing a sequence stratigraphic framework for the study succession. The later uses age dating data, depositional environments and sub-environments of the studied units via detailed well logs analysis and seismic attributes.
The methodology to do this, can be summarized as follows: 1- studying the stratigraphy of the study area using the well log data. 2- Predicting the depositional sedimentary environments by integrating detailed well logs and numerous seismic attributes analysis. 3- Initiation a sequence stratigraphic framework via major sequences, traditional sequences, depositional sequences and para-sequence sets & para-sequences using both seismic and well logs analysis. 4- Elucidating a correlation of the suggested units via vertical, lateral and spatial distribution using both seismic and well logs analysis. 5- Determining the lateral, vertical and spatial distribution of porosity in the reservoir units of the Eromanga sequence from well logs data. 6- Delineating the suggested leads and prospects by integrating all the available data. |
