Another top drive enhancement, Twister, enables the top drive to put minor oscillations in the drill string to reduce friction when slide drilling. The play was most likely a response to the popular Eastward Ho by Ben Jonson, George Chapman, and John Marston, which was in turn a response to Dekker and Webster’s second collaberation, Westward Ho of the previous year. The rig has a 1 1/8-in. “Control of the rig is done with a human/machine interface where a driller in a cyber chair uses a joystick, PLC (programmable logic controller) and touchpad commands to operate the top drive, drawworks and iron roughneck in a climate-controlled environment with cameras and data monitors,” he continued. promo. The official magazine of the International Association of Drilling Contractors, DC has been published since 1944 and is the longest continuously published magazine focusing on drilling and completion. “Like most unconventional plays, the Bakken features tight oil or gas formations, and every operator has a different way of drilling the hole – some are vertical, some horizontal and some are S curves,” said Jay Thiessen, onshore global business development manager. Nabors Drilling USA’s rigs account for 57 of a total 230 in the Bakken. Transportation costs associated with moving a ramp to the well site also can be reduced. With 57 active rigs out of a total Bakken rig count of 230, Nabors Drilling USA (NDUSA) is the largest contractor in the play. Change ), You are commenting using your Facebook account. To improve rig performance, NOV has developed top drive software enhancements to reduce stick-slip and to help the directional driller maintain tool face. “The rigs also can move from pad to pad or well site to well site in three to four days.

Further, Mr Slaughter noted that 96-ft to 112-ft masts on more conventional rigs may have problems clearing taller wellhead control equipment. “For example, the driller can input a certain desired rotational angle into the system, and Twister will automatically compute and rotate the top drive a specific degree to achieve the desired angle of rotation downhole.”, Safety is another major focus. 2 oil-producing state, surpassing Alaska and trailing only Texas. In cases of pad drilling, the spacing is often very tight.”. “This is an efficient and cost-effective system that maintains tripping operations of the rig, mimicking the work of a derrickman in process, while safely removing him from the fingerboard,” said NOV product technical manager Joel Heinen. H&P’s FlexRig3 is designed to accommodate a single-direction skid system that allows the rig to drill either a single-well pad or a single row of wells on a pad. “The technology also aids the directional driller in maintaining tool face, or orientation of his directional drilling tools,” he said. ( Log Out / Northward Ho was published in … Keeping the rig on the ground rather than on a platform enhances safety by providing more stability, he said. NORTHWARD, HO! “We’re now drilling 10,000- to 12,000-ft laterals and recently extended to 14,000-ft laterals.”, The Flex3 rig, which has a fully integrated AC drive system, has a skid feature that allows the rig to skid effectively from well to well in a matter of hours. The pump horsepower and hydraulic torque specifications of the PACE-B rigs’ top drive system are designed with enough capacity to reach 21,000-plus ft well depths with long horizontal sections. Her goals are to think outside the box—and always play by her own rules. Northward ho! Operators also are testing horizontal drilling applications for drilling the 11,000-ft vertical wells in these plays. “We are now typically running 40 stages per well.”. “This saves time and allows for simultaneous operations on the rig, he added. The play was most likely a response to the popular Eastward Ho by Ben Jonson, George Chapman, and John Marston, which was in turn a response to Dekker and Webster’s second collaberation, Westward Ho of the previous year. Globe Energy Services has designed a five-axle land rig providing quick rig-up/rig-down operations, a mast with 116 ft of clearance and an adjustable drilling floor. But while drilling plans vary, a common theme in the Bakken is that operators are drilling long, extended laterals, which is why pad drilling is so prevalent, said Niels Meissner, product technical manager for NOV. “For any unconventional tight oil or gas formation, in order to maximize the productivity of the well, an operator must maximize contact of the borehole with the productive part of the formation,” he said. “The multi-well pads limit the footprint and the impact on the infrastructure and communities,” he explained. Most commentators consider it to be superior to the earlier play, but are in disagreement as to how much share each of the two playwrights have in it.

Opportunities to deploy additional rigs to the Bakken and Eagle Ford are possible as well, according to Johnny Slaughter, vice president of well services.

Champion Evaluating Thomas Dekker as a dramatist is an extremely difficult task because his work is so diverse in kind and quality and because so much of it was written in collaboration. Carol Romeo recommends Northward Ho! The box-on-box design is climate-controlled with an enclosed system to allow for drilling in the winter.

However, the rigs need to be mobile and, ideally, truck-mounted,” Mr Williams said. But the play is just one of seven petroleum systems, or “pools,” that have been identified in the Williston Basin, suggesting “huge potential in upcoming years, much more than just the Bakken,” said Dr Steve Sonnenberg, professor of petroleum geology at the Colorado School of Mines and chair of the Bakken Research Consortium, a group of 35 companies researching the various aspects of the play. “The standardization of the 1,600-hp and larger mud pumps is allowing us to drill wells in as short a time as 12 days and increase our rates of penetration (ROP) dramatically,” Mr Williams said. “The taller mast is a key element of this new rig, because the operator can rig up and clear the wellhead control equipment from the ground instead of a ramp,” Mr Slaughter said. The company is drilling 10,000-ft to 12,000-ft laterals and recently extended to 14,000-ft laterals.
