Breitling Energy Technology and Operations
The development of seismic imaging in three dimensions greatly changed the nature of oil and natural gas exploration. This technology uses traditional seismic imaging techniques, combined with powerful computers and processors, to create a three-dimensional model of the subsurface layers.
Coiled tubing technologies replace the traditional rigid, jointed drill pipe with a long, flexible coiled pipe string. This greatly reduces the cost of drilling, as well as providing a smaller drilling footprint, requiring less drilling mud, faster rig set up, and reducing the time normally needed to make drill pipe connections. Coiled tubing can also be used in combination with slimhole drilling to provide very economic drilling conditions, and less impact on the environment.
Measurement-While-Drilling (MWD) systems allow for the collection of data from the bottom of a well as it is being drilled. This allows engineers and drilling teams access to up-to-the-second information on the exact nature of the rock formations being encountered by the drill bit. This improves drilling efficiency and accuracy in the drilling process, allows better formation evaluation as the drill bit encounters the underground formation, and reduces the chance of formation damage and blowouts.
Slimhole drilling is exactly as it sounds; drilling a slimmer hole in the ground to get to oil and natural gas deposits. In order to be considered slimhole drilling, at least 90 percent of a well must be drilled with a drill bit less than six inches in diameter (whereas conventional wells typically use drill bits as large as 12.25 inches in diameter). Slimhole drilling can significantly improve the efficiency of drilling operations, as well as decrease its environmental impact. In fact, shorter drilling times and smaller drilling crews can translate into a 50 percent reduction in drilling costs, while reducing the drilling footprint by as much as 75 percent. Because of its low cost profile and reduced environmental impact, slimhole drilling provides a method of economically drilling exploratory wells in new areas, drilling deeper wells in existing fields, and providing an efficient means for extracting more oil and natural gas from un-depleted fields.
Used to free oil and natural gas that is trapped in shale rock formations. A liquid mix that is 99 percent water and sand is injected into the rock at very high pressure, creating fractures within the rock that provide the oil and natural gas a path to flow to the wellhead. The fracking fluid mix also helps to keep the formation more porous. Hydraulic fracturing is now widely used, with more than 90 percent of the oil and natural gas wells in the United States having used it to boost production at some time.
