many potentially prolific producers have already been plugged and
abandoned , owing to lack of adequate formation evaluation . For
example , In the early days of log analysis، it was common practice
to regard water saturations above 50% as non-com
mercial.
However, with advances in logging and seismic technology came
the realization that some of those supposedly non-commercial zones
were، in fact، highly productive pays , depending on pore-size
distributionof the rock , movable or immovable fluids and
production probability .
This research highlights on new manner in study of petroleum
reservoir , by integrated between a sedimentary study, which
comprises micro slides from side, and geophysical well logging
interpretation from another side, in Juriba & Transition zone
formation, in ELmhash structure oil field , at Euphrates depression
– west DER Azzor -Syria.
A selection (5) wells in ELmhash structure is Mahash (17-18-11-4-
