ABSTRACT

This paper summarises the results of the first phase of oil & gas exploration of the
B-Golitza Block. A revised geological framework will be presented, which puts the
stratigraphy in a chronostratigraphic scheme, incorporating sequence stratigraphic
architecture. Use of a chronostratigraphic framework for exploration of the block has
enabled the exploration Play Elements to be identified and both their stratigraphic and
aerial distribution to begin to be determined within an integrated methodology that
incorporates seismic data, well data and fieldwork.
The work conducted during the first phase of the exploration period has focused
on identification of the prospective Play Fairways within the block and determining
the structural and basin evolution of the area. The distribution of the Play Fairways is
now beginning to be understood within the block and has led to the block being subdivided
into areas which are thought to have different exploration risk profiles. This
paper will present the preliminary exploration models for Play Fairways, structure and
structural evolution of the area. The paper will also discuss the critical risk elements
within the main Play Fairways and how these risks are being addressed by technical
work. A series of seismic lines will be shown that cross each of the play fairways and
illustrates the main components of the play.
The conclusion will focus on what has been learned during the first exploration
term and what exploration problems remain.
