چکیده
The main purpose of this study is to estimate hydrocarbon potentialities Yamama Formation (Valanginian–Early Hauterivian) by using assessment technique links up between gamma ray spectrometry logs and other conventional open hole for determining the petrophysical properties units in Subba oil-field oil water contact as well. Lower (YB); considered reservoir unit, aptly composed shallow high depositional energy levels oolitic bioclastic grainstone facies reflecting low clay-content, thus these had gave a fruitful chance immigrated accumulate porous bodies units. non-improved upper member (YA) due far-deep conditions reflected well-developed dense-compact sub-tidal open-shelf lagoonal benthic foram / algal wackestone sparse-fossiliferous lime mudstone intercalated with facies, are clearly displayed sedimentary intervals clay-content that is, reduction potential highly affected on facies.YB-unit have attained (22-29m) net pay thickness porosity (9.35-10.9%) saturation ranged (40-40.6%),whereas YA-unit net-pay reached (7.5-16.5 m) (6 % phi) (35.3%Sw). at lower may assign depth 3573m (MSL) southern dome basis electrical monitoring, well log interpretation test results carried out formation

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Geological Field Mapping
A map showing the distribution of rock units and structures across a region representation, usually on a plane surface is termed a geological map. A map showing the occurrence of structural features across a region, the distribution of rock units, and their type and age relationship is termed a geological map. Geological field mapping is the process of selecting an area of interest and identify...
