Petrophysical Analysis with EXCEL, TECHLOG & PETREL

In this lecture I would walk you around petrel user interface in preparation for reservoir description. And at end, you would be able to understand petrel user interface

Here you would learn how to load data to petrel software and at the end of the lecture you would be able to upload data to petrel software

In this lecture you would learn data adjustment on petrel software

This lecture would show you how to use petrel software to carry out reservoir description and at end of the lecture you would understand the importance of reservoir description

This is where you would learn major petrophysical parameters such as porosity, water saturation and permeability

This lecture marks the beginning of petrophysical analysis of well logs data. In this lecture we are going to use excel spreadsheet program to calculate volume of shales. Please find the attached data

Here you would learn how to use excel to calculate density porosity, average total porosity and effective porosity using excel spreadsheet

This lecture would help you to learn how to use excel spreadsheet to calculate water saturation and then you would be able to divide reservoirs into pay and non-pay zones

In this lecture you would learn how to use excel to plot gamma ray log against depth and resistivity log against depth, and at the end of this lecture this would enable you to differentiate sands from shales on logs (graphs)

This is where the calculations of petrophysical parameters begin. At the end of this lecture you would learn how to use excel to calculate gross thickness, net thickness, net pay thickness, net-to-gross, average porosity and average water saturation for sand I

This lecture would teach you how to use excel to calculate gross thickness, net thickness, net pay thickness, net-to-gross, average porosity and average water saturation for sand II. And at the end of this lecture you would fully understand how to use excel spreadsheet to calculate petrophysical parameters

This is where petrophysical analysis of well logs using techlog software begins. In this lecture you would learn techlog user interface and how to load data to techlog software

In this lecture you would learn how to adjust well log data to standard on techlog software

This is where you create zones for your reservoirs. At the end of this lecture you would learn how to create zonation for reservoirs using techlog software

In this lecture I will show you how to create depth references and then you will learn how to locate wells on a base map on techlog software

In this lecture you would learn 2 methods of calculating volume of shales on techlog software

The next step is to calculate effective porosity and total porosity, but before then you need to obtain RHOB shale and NPHI shale. These 2 parameters will be useful in effective porosity and total porosity calculations. So at the end of this lecture you would learn how to obtain RHOB shale and NPHI shale and then you will learn how to calculate effective porosity and total porosity on techlog software

In this lecture I am going to show you the processes of obtaining water saturation when the reservoirs are Oil-down-to (ODT)

In this lecture we will continue the processes of obtaining water saturation when the reservoirs are Oil-down-to (ODT)

Finally on water saturation, this lecture would teach you how to obtain Rw and then you would learn how to use Rw to calculate water saturation on techlog software

The next step is to run the summary. But before we run the summary we need to put in place cut-off values. So in this lecture you would learn how to input the cut-off values and then you would see how to run the summary on techlog software

This lecture would show you how to prepare a petrophysics table or a table of rock properties

This is where you would learn how to interpret a petrophysics table. So at the end of this lecture you would learn how to interpret and compare the result of X-1 well with the result of  X-2 well

In this lecture I will show you how to combine different log curves in order to represent your reservoir.  So at the end of his lecture you would see how logs combination is used to design a fluid distribution for X-1 well

This lecture would show you how logs combination is used to design a fluid distribution for X-2 well

In this lecture you would learn how to calculate oil volumes (OOIP, STOOIP and Recoverable oil)

This is where you would learn how to carry out gas volume calculations (OGIP, GIIP and Recoverable gas)

This is the conclusion of the entire course and of course the last lecture. So in this lecture we would review all we have learnt in the previous lectures and then we would make conclusion.
