| Abstract | ||
| A number of logs have been studied, represented by the Gamma Ray Log, the Density Log, the Neutron Log and the Sonic Log for a number of wells in the Jambur and Kirkuk oil fields in northeastern Iraq, namely the Ja-40 well, the K-243 well and the K-411 well for the Aaliji Formation and the Jaddala Formation formation, through which the total size of the shale was determined based on the Gamma ray log reading by special equations and then the total porosity was determined based on the reading of the density and neutron logs. After being corrected from the influence of gas using approved mathematical equations. The primary porosity was calculated using acoustic sensor reading after being corrected from shale and hydrocarbons effect and then calculating the secondary porosity from subtracting the primary porosity from the total porosity. After that, the study compositions in each well were divided into five reservoir units for both formations from top to bottom (A, B, C, D, E) and determine which is the best porosity and which is the least porous, as it was found that unit A in the upper Jaddala formation of the best porous units while unit E below Aaliji formation of the lowest porous units. | ||
