Reply #10: Halliburton is the inclination drilling king [View All]

Back in 2000 I found this info on Halliburton's main page. After I cited it in connection with the pre-war angledrilling into Rumailiah it was pulled from the site.

FOR IMMEDIATE RELEASE: August 18, 2000 HALLIBURTON ENERGY SERVICES PARTICIPATES IN DRILLING WORLD RECORD INCLINATION WELL DALLAS, Texas - Baroid Drilling Fluids, a product service line of Halliburton Energy Services, participated in the successful drilling of one of the world’s most extreme inclination wells in the South China Sea off Brunei, drilling to an angle of 164.7 degrees. Utilizing Baroid’s PETROFREE drilling fluid system, the Operator drilled several wells that have set both local and corporate world records while minimizing risks to the environment. Halliburton Energy Services is a business unit of Halliburton Company (NYSE:HAL). For the Brunei well, Baroid’s PETROFREE vegetable ester based system was selected as the best option because of its excellent inherent lubricity and hole cleaning characteristics, as well as its superior toxicity and biodegradability performance. Rotary steerable technology was used, in conjunction with PETROFREE, to first drill the development portion of the well and then to drill the field delineation portions. Using this process, the operator was saved the time and cost of drilling additional conventional exploration or delineation wells. The savings coupled with the environmentally responsible nature of the fluid limited the operation’s influence on the local environment. “We are thrilled to be a part of this world record setting success.

This is another example of how cooperation and communication between partners, technologically advanced and environmentally friendly products, and the ability to make real time changes can optimize our customers’ reservoir performance,” said Jody Powers, president, Halliburton Energy Services. Although initial plans were not set to drill at such an extreme inclination, geologists on-site requested the alteration to intersect a particular formation early, increasing the inclination to approximately 160 degrees. The successful use of PETROFREE at the site further demonstrated the product’s superior hole cleaning and lubricity characteristics. The calculated coefficient of friction at Total Depth (TD) - 5,730 meters (18,794 feet) - was 0.21 to 0.22. The maximum Total Vertical Depth (TVD) was approximately 2,918 meters (9,571 feet) and the well was at 90 degrees or higher since 2,900 meters (9,512 feet) Measured Depth (MD). In addition to the PETROFREE drilling fluid, Baroid’s DFG+Win Hydraulics and Downhole Rheology modeling software package was used to ensure that surface rheology data accurately reflected down hole requirements for hole cleaning and cuttings transport. At TD the hole was circulated until the shakers cleaned up and the bit was pulled without pumping or back reaming. Due to the fact that there were no constraints on torque and drag levels, the well could easily have been drilled further, if the angle had been increased a further 15.3 degrees it would be drilling vertically upwards back towards the surface. Halliburton Energy Services provides products, services, and integrated solutions for oil and gas exploration, development, and production. Capabilities range from initial evaluation of producing formations to drilling, completion, production enhancement, and well maintenance - for a single well or an entire field. With more than 300 service centers in more than 90 countries, Halliburton possesses the global perspective that is increasingly important for energy exploration and production. Founded in 1919, Halliburton Company is the world’s leading diversified energy services, engineering, energy equipment, construction, and maintenance company. In 1999, Halliburton’s consolidated revenues were $14.9 billion and it conducted business with a workforce of approximately 100,000 in more than 120 countries.
