The first edition of the Drilling Data Handbook was printed in 1950. The book has been improved over the past 60 years, adding lots of new technologies and equipment in its eight additional editions. It remains familiar and friendly to users. Its philosophy has always been to give quick access to the basic information or calculations for the office or field operations. That is why we consider that our task is to select and highlight the most important data, charts, and formulas. The Drilling Data Handbook tries to combine international and field units for the benefit of a majority of people from different technical cultures. Past editions' success strengthened the authors in persevering and publishing a new paper edition. A large number of field personnel have confirmed the Drilling Data Handbook as their reference, now in combination with electronic documents and the Internet. This edition refreshes and updates data and references of the eighth edition, but also includes more information. The ninth edition of the Drilling Data Handbook was published in 2014. We are in a new millennium and the communication techniques have considerably evolved. The electronic hardware and software allow fast communication anywhere in the world, access to huge databases, as well as permanent refreshing of the documents required by the drilling personnel. At the moment of making a decision about a new edition of the Drilling Data Handbook, the question was: is it pertinent to do an electronic version on a CD support, a web-accessible one with a connection to different sites, or to keep the popular concept of the paper "green book" as people have been using it for decades? The Internet gives access to an infinite volume of information but everybody has experimented the trouble of being lost in the way, or the difficulty to reach specific technical information. The Drilling Data Handbook does not want to compete with the web sites of the manufacturers, or other sources of electronic documentation. The main goal of our contribution to the drilling industry is to give access very quickly and without any additional resources to the fundamental data at the office, or at the rig floor. That is the reason why we made the decision to present you this reviewed and updated Eighth Edition in the formula you are familiar with, and we hope that it will continue to help you when planning and driling your well.
