We employees and customers define deephole as drilling to depths ranging from about 300 to 10,000 feet. around the world With a product range saturating the water well and oil and gas markets, we plan to use this tool to develop our business and offer training for our employ- ees and customers around the world. Atlas Copco was founded in 1873, and has always had innovation at the core ” of its identity. In 1972, nearly 100 years after the company was founded, Atlas Copco began producing rigs for drilling gas and CBM wells. Now, as we flash forward to 2014, Atlas Copco has produced over 1,000 deephole drills for the water well and oil and gas industry within the last two decades. Customer interaction, training, new product development and increasing manufacturing capacity are all important factors to help us grow. We continue to improve and develop our current product portfolio that includes our water well product line, RD20 product line, as well as the newest addition to our oil and gas product line: the Predator Drilling System. New product development is always first in mind at Atlas Copco, and it’s something that we will divert great attention to in years to come. Whether it’s improving our current fleet or looking into different solutions to help our customers, our engineering and marketing team has been working to better understand our target markets. Our teams have been traveling around the world to meet our key customers and sales companies to discuss their needs and wants in the oil and gas, water well, geothermal, and exploration markets. In an ever-changing environment, we at Atlas Copco are working to adapt and grow with the changes our deephole customers face. We will continue to strive to offer the best products for our customers, and carry on with educat- ing our employees and customers on our product offerings. We’re excited about the possible synergies we can extract from the larger Atlas Copco organization, specifically with our colleagues involved with rock drilling tools, compressors, and rental. You will see those synergies come together in this book, and we will continue to contact our key custom- ers and sales companies around the world to discuss the deephole business. We encourage feedback from our production and maintenance personnel who work with our rigs to help guide our improvements, and hope to be able to share our mutual success stories in future editions of our Deephole Well Drilling reference guide. We hope you enjoy the first edition.

Since then, the ever-increasing need for hydrocarbon-based fuel sources has rapidly driven innova- tions in technology and technique to make almost any resource ac- cessible to the modern driller. Today’s well drilling practices can be traced back to the copper digging tools of early civilization, though their evolu- tion was not at all a steady progression.

  • Tom Kilburn: a Tale of Five Computers
    Tom Kilburn: A tale of five computers One of the pre-eminent figures in the early history of computer design was Tom Kilburn. Over the course of some thirty years, he made significant contributions to the development of five important computers. Although a natural team leader possessed of a somewhat dominating personality, who inspired in those who worked closely with him great loyalty and affection, Kilburn was, on casual acquaintance, a self- contained man who chose his words with care. As F.C. Williams put it “What you must always remember is that Tom is a Yorkshireman.”1 Early Days Tom Kilburn was born on the 11th August 1921, near Dewsbury in West Yorkshire, England. His father, John William Kilburn, was a statistical clerk who rose to become a company secretary.1 Tom had a somewhat specialized education at Wheelwright Grammar School having been permitted by his headmaster to study almost nothing else from around the age of 14. It was hardly surprising therefore he emerged from school as something of a mathematical specialist. In 1940, Kilburn went up to Sidney Sussex College, Cambridge, with State, Dewsbury Major, and Minor Open Scholarships. Wartime courses at Cambridge were somewhat truncated and in 1942, Kilburn graduated with First Class Honors in Part I of the Mathematical Tripos and in the preliminary examination for Part II. During the Second World War, many Cambridge mathematics dons were absent from the university serving at Bletchley Park and elsewhere. In spite of this, there remained a lively mathematical community in which Kilburn played a full part part.
