The collegeof science at the University of Basrah organized a seminar on the study of the petrophysical properties of the Yamama formation in the halafaya oil field, southern Iraq.
The seminar, which was attended by researcher Hussein Abdulamir Abdulwahid, included presenting the results of analyzing the data of a number of wells in the field using the Techlog and petrel programs, where the well records such as gamma rays, resistivity, neutron and density were interpreted to determine the type of rock and estimate porosity, hydrocarbon saturation and mud volume. The results showed that the formation consists mainly of limestone with overlays of clay limestone and baby, and was also divided into stratigraphic units YRA, YYRB and YYRC. The study indicated that the YRA unit has higher resistance values and greater hydrocarbon saturation, and the results showed the presence of changes in the ratio of clay and minerals and their impact on porosity and permeability inside the reservoir. The workshop recommended the importance of integration between geological and petrophysical studies using rock core analyses, and also recommends the use of advanced sensors to obtain more accurate results such as SENSNMR, FMI .
