While breaking out as a drilling supervisor in 1980, there were no cell phones or accessible computers. Communication with the office consisted of dictating the daily drilling report to the superintendent on an early morning call from a pay phone or ranch radio. Thus, most decisions were made by the supervisor with limited or no input from anyone else. I soon realized how ill-equipped I was to manage the long list of responsibilities my job required. In the absence of good data, a lot of decisions were based on "rules of thumb", intuition or "that's the way we've always done it".
For the next several years, working as a drilling supervisor, I collected and used a wide variety of workbooks, slide rules, card reader calculators and even learned how to write code in BASIC on an early generation computer. Calculating system pressure drop was a laborious process regardless which method was used and the result was usually not very accurate. Directional survey calculations were typically left completely to the directional professionals.
In 1998, the first version of DRLPRO was marketed and within a few short years pirated copies outnumbered licensed copies by probably 10 to 1. Between 2005 and 2016 the software was off the market but went through many upgrades and additions, thanks in large part to the ideas and suggestions from a select team of outstanding drilling professionals I had the privilege of working with.
So there you have it. DRLPRO3.0 is the product of decades of evolution in improving the quality, speed and scope of accessing and evaluating the critical information drilling leaders need in order to make informed technical decisions. Also, I hope you will agree, that it is presented in a comprehensive, non intimidating, user friendly format.
In 1988, while working in the GOM for Mobil, I was introduced to an Apple Macintosh with Microsoft Excel. Granted, it was a pretty basic version of Excel (less than half a MB and came on a 3 1/2" floppy) but it was a game changer! Equations could be written into cells, and variables from other cells could be used in the equations that included choices based on logical statements. I purchased my own Mac in 1989 (1MB of RAM and a 20 MB hard drive) and created spreadsheets that performed a wide range of drilling calculations. Years later, I switched to PCs. Each new version of Excel brought enhancements which enabled more complexity to the technical drilling calculations.
