Abstract
The hydrocarbon potentialities of Abu Madi - El Qar’a Field of Abu Madi Formation
have been evaluated through the integration of stratigraphic sequence, burial history and well
logging analysis in the present work.
Abu Madi Formation is mainly intercalation between shale, siltstone and sandstone as
reservoir. The shale bodies which separated the sand bodies are considered as a good sealing and
trapped, the sand bodies are found in lens shape or bodies, the study intervals are not covered by
continuous sand lenses. That is they are deposited in channelized Paleo-valley, They are affected
by Paleo-high, the geometry of the depositional environment and Pal eo- morphology of the
study area.
Study of seismic sequence analysis of Abu Madi Formation indicates that the lower and
Middle units of level III sands are characterized by a good lateral continuity, high sand/shale
ratio and sheet-like geometries while Upper level III section is heterogeneous with rapid lateral
facies change producing a poor lateral continuity Therefore, the lower and middle level III sands
are considered as a good quality reservoir whereas the upper level III sands are considered as
poor quality reservoir.
A comprehensive multidisciplinary study of the Abu Madi-El Qar’a area was carried out
using the mesoscopic reservoir heterogeneities scale in order to evaluate the reservoir
characterization, define the environment of deposition and to delineate the geometry and
Iithofacies distribution, laterally and vertically, for Abu Madi reservoir sand units. Lithologic
interpretation and formation evaluation were made for Abu Madi reservoir encountered in nine
wells. This has been achieved through integration of borehole data and a comprehensive well
logging analysis of the Abu Madi Formation.
The logs of all reservoir zones were analyzed using landmark Geographix Explorer
package to differentiate between siltstones, non reservoir, and thinly laminated sands, and to
prove additional reserves. The maps of the reservoir parameters indicate that the level III
extension to the south contributing further confirmation to the results derived from the seismo-
stratigraphic analysis and geological studies.
Regional burial history pattern, thermal maturity variations and source rock assessment of
the sedimentary succession in the Abu Madi / El Qar’a Field were modeled using Basin Mod 1 D
program. The modeled results indicated that the majority of Abu Madi kerogen belongs to
mature type III in the principal zone of oil generation (oil window) , where R., values range from
0.5 to 1 % with small amounts ofkerogen immature type Ill, where R., is less than 0.5%.
Depth Structural contour map on top of Abu Madi Formation level Ill, suggested the
possibilities of two leads, which are structural controlled, If these two leads be promoted to
prospects, they will represent potential reserve additions in the study area.
