Abstract
Miocene-Pliocene reservoir contributes the main gas production in
onshore Nile Delta, Egypt, the paleo deposition environment distribution
should be recognized and understand. Petrophysical analysis, seismic study
was carried out at West Manzala and West Qantara area. The workflow
combined seismic elastic properties, regional geological context,
biostratigraphy and petrophysical reservoir properties in order to characterize
the Miocene-Pliocene reservoir.
Wireline log analysis used to understand the petrophysical properties.
Seismic interpretation was used to detect the subsurface structural and
stratigraphic features. The results were collected together to build-up the
reservoir static model.
Static model is representative tool to imagine the facies, petrophysical
properties and structure of the study area. Such static model can support the
detection of suitable places for hydrocarbon potential. Static model of
Qawasim Formation in El Bassant area shows a combined trap formed of
faulted 3 way dip closure with pinching out stratigraphic feature with
Northeast- Southwest trend. Qawasim Formation consist of tidal dominated
and fluvial dominated deposits, consequently , this study shows the Qawasim
is composed of sand-shale intercalations with different types of sands (fluvial
and tidal). Facies model is divided into 4 lithofacies description (shale, poor
quality sand, fair quality sand and good quality sand). The Qawasim
sedimentation seems to be affected by growth faults which generate
accommodation space leading to sediments accumulation around El Bassant
area. The sequences were represented mainly by fluvial sediments. Qawasim
modeling help to minimize the drilling risk by selecting the optimum location
for new wells as structural and facies.
