A roller-cone bit is a drill bit used for drilling through rock that features 2 or 3 abrasive, spinning cones that break up rock and sediment as they grind against it. Roller-cone bits are typically used when drilling for oil and gas. [1] A water jet flowing through the bit washes out the rock in a slurry. [2]
Hughes's two-cone rotary drill bit, nicknamed "rock eater", penetrated medium and hard rock with ten times the speed of any former bit, and its development revolutionized oil well drilling. [ 4 ] It is unlikely that he actually invented the two-cone roller bit, but his legal experience helped him in understanding that its patents were important ...
The factors affecting drill bit selection include the type of geology and the capabilities of the rig. Due to the high number of wells that have been drilled, information from an adjacent well is most often used to make the appropriate selection. Two different types of drill bits exist: fixed cutter and roller cone. A fixed cutter bit is one ...
The company was established in December 1908 [1] as Sharp-Hughes Tool Company when Howard R. Hughes Sr. patented a roller cutter bit that dramatically improved the rotary drilling process for oil drilling rigs. He partnered with longtime business associate Walter Benona Sharp to manufacture and market the bit.
In 1909, Baker's competitor Howard R. Hughes, Sr. patented the first roller cone drill bit, which made it possible to drill through deeper, harder rock. This was the basis for the Hughes Tool Company. [2] [13] [14] [17] Baker organized the St. Paul Consolidated Oil Company on September 24, 1910, with USD$600,000 in capital.
Yellen said in an interview that the U.S. and its allies also could consider lowering their $60-per-barrel oil price cap on Russian oil, which prohibits Western insurance and maritime services on ...
The original part of the company, Smith Bits, grew out of a blacksmith shop in the small town of Whittier, California, in 1902. It was there, at the age of 20, that Herman C. Smith became the right man in the right place at the right time: oil was discovered nearby and the local drilling operators needed their fishtail bits sharpened.
Drill bits are broadly classified into two main types according to their primary cutting mechanism. Rolling cutter bits drill largely by fracturing or crushing the formation with "tooth"-shaped cutting elements on two or more cone-shaped elements that roll across the face of the borehole as the bit is rotated.
