The emerging fracture porosity exploration play within the
Jurassic Najmah – Sargelu
carbonates may hold considerable exploration upside for the country of fault
network and the varying lithologies observed in these
intervals to that of fractures densities and orientations is essential to the
successful execution of this high potential exploration play.
Several major tectonic episodes have influenced the present day
structural morphology of onshore regime
.
The Middle to late Jurassic Najmah – Sargelu interval represents the deposition within three
second-order cycles in a mid to outer ramp and basinal
setting. The lithologies observed vary greatly within
these two intervals and have been described, from core, as wackstones,
mud rich to mud poor packstones and grainstones. These lithologies
are greatly dependent upon the development fracture porosity for commercial
viability.
Geomechanical fracture models have been introduced
into the Jurassic exploration program, in
