Formation Evaluation with Pre-Digital Well Logs covers the practical use of legacy materials for formation evaluation using wireline logging equipment from 1927 until the introduction of digital logging in the 1960s and ‘70s. The book provides powerful interpretation techniques that can be applied today when an analyst is faced with a drawer full of old “E logs." It arms the engineer, geologist and petrophysicist with the tools needed to profitably plan re-completions or in-fill drilling in old fields that may have been acquired for modern deeper and/or horizontal drilling. Includes more than 150 figures, log examples, charts and graphs Provides work exercises for the reader to practice log analysis and formation evaluation Presents an important source for academia, oil and gas professionals, service company personnel and the banking and asset evaluation teams at consultancies involved in reserve and other property evaluation

While the first well logs recorded seventy years ago had no provision for data quality control, the development of increasingly sophisticated logging techniques has led to the introduction of a large number of tests to validate acquired data. Log quality can be assured by stringent control of depth, calibrations, signal processing and operating procedures. This work gives a thorough description of these features. The meaningful interpretation of well logs depends on valid input. An understanding of log acquisition, and the performance of rigorous quality checks are the prerequisites for an accurate evaluation of a formation. These elements also enable log users to make decisions based on calculated risks. The book is primarily written for earth science specialists who use log data. It also addresses the needs of logging engineers who seek a better understanding of the log acquisition process. Exercises and their solutions are scattered in the book to complement practical chapters. Contents : I. Premises. 1. Introduction. 2. Evaluation of hydrocarbon volume. 3.

Did you know that setting aside 15 minutes at the end of the day to record in a Work Log and reflect on your day can boost your efficiency and thus impact your career success? In addition to this, a Work Log is a record of actions, events, accomplishments, and incidences. Record activities in your Work Log hourly, daily, weekly or even monthly. But why is it important to keep a Work Log? A Work Log: a. Helps to keep a record of your daily activities such as clocking in and clocking out times b. Helps to record tasks that you accomplish throughout the day, c. Can be used to keep only important information, without too much detail d. Allows you to record when and who gives you a task or to whom you give a task, e. Allows for easier preparation of reports by referring to your Work Log, f. Can be used to record sick days, absences, lunch time and even your salary, g. Provides a hard copy in your own handwriting, h. Assists you in providing legal evidence in case of legal proceedings against you, Choose from our wide selection of Work Logs and customize it to match your needs.
