The file is attached. Below is a typical example of a Gamma Ray (GR), Photo Electric Factor (PE or PEF), Neutron (NPHI) and Density (RHOB or DEN) log, showing their response for different lithologies and fluids.

Agganitk, Do you have a question about the log or is it just posted to share? These examples do show the basics of log analysis, but I feel a resistivity log should also be included to provide assurance on hydrocarbon presence, rather than only density and neutron crossovers in very very very clean sands like happens here. |

I have posted it for just to share. Yaaa.. thanks for reminding... Clay minerals can also give separation in den and neu porosity curves. |

ok, thanks for sharing! Have you taken any steps towards becoming a petrophysicist btw? |

Nothing specific... only change is decision to read/refresh available material and keep on increasing knowledge with time .. |

Hi, at scale the percentage goes from 60 % to 0. What does it mean ? |
