CRAIN'S PETROPHYSICAL HANDBOOK

Browsing the internet the other day, I found a brilliant resource on log analysis titled Crain's Petrophysical Handbook. It is divided into 5 main parts:

• Petrophysics-log Analysis
• Seismic Petrophysics
• Reservoir Description
• Petrophysical Data
• Completion integrity

You can purchase a shareware copy for just $60. The book itself is in the process of completion as more topics are added by the author, E. R. (Ross) Crain, P.Eng. who has been a petrophysics consultant since 1973. You can also register for seminars from the website.

Petroleum Engineering Calculations

Petroleum Engineering involves some very complicated and cumbersome calculations. Browsing on the internet i came across a very useful website (peteng.com) that greatly simplifies the work and reduces the time involved. The following calculations can be performed simply by inputing the required parameters in a form that comes up when you click the link for a particular calculation.
This work is credited to Dr. Haveluck Gbubemi Harrison, [MSc (Imperial), PhD (Heriot-Watt) ], E&P Information Management Consultant.

Download petroleum engineering books for free

Petroleum engineering books are generally very expensive and most students cannot afford to purchase them. The best option they have is to use a library. However there is a limit to the amount of books one can borrow from a library. Another way is to scan the book and make a pdf file and store it on your pc for reference. You can have a whole library of scanned books on your pc. However you will require a scanner to scan all those pages.
There remains however another option to access those expensive books; the option of sharing. The website 4shared.com has a collection of many petroleum engineering books, shared by the users of the website. You can download these books for your own use. All the books are actually scanned copies, as discussed earlier. Here is a list of a few titles that can be found at 4shared.com

• HANDBOOK OF PETROLEUM REFINING PROCESSES
• William D. McCain - The Properties of Petroleum Fluids
• William C. - Standard Handbook of Petroleum and Natural Gas
• Micheal Economides - Petroleum Production Systems
• Craft - Applied Petroleum Reservoir Engineering
