State-of-the-art equipment and technology enables DWS to hit previously unachievable lengths in Appalachian Basin
ZELIENOPLE, Pa. – Deep Well Services (DWS) has literally gone to great lengths to revolutionize its snubbing capabilities in the oil and gas industry.
The Pittsburgh-based oilfield service company is among the leaders in utilizing snubbing units capable of reaching extended laterals in the Appalachian Basin.
“There isn’t a horizontal well length that our 285K units can’t TD or mill out in this basin, and beyond,” said John Sabo, Chief Operating Officer at DWS. “We can reach the lengths the industry will need to achieve as the challenges and goals we face continue to evolve. We can attain virtually every on shore scenario out there with this new technology.”
“With the ever improving hydraulic and rotary technology,” Sabo continued, “we continue to revolutionize our equipment to better serve the needs of producers within the basin. Lateral lengths that previously would have been unachievable are now well within the realm of our equipment’s capabilities.”
Extended laterals are drilled horizontally, as much as four miles from the well pad. The strategy of extending the horizontal reach of the wells has made an economic impact for the oil and gas companies while also enabling those in the field to establish new standards.
Deep Well Services had a significant role in the completion of the record-breaking, 18,544-feet lateral Purple Hayes liquid rich natural gas well in Guernsey County, Ohio, in 2016. Eclipse Resources drilled the Utica play well, which is thought to be the longest horizontal on-shore gas well in the United States and also the longest achieved via a hydraulic snubbing rig in the Appalachian basin.
DWS has a modern fleet of snubbing units suited for extended lateral ventures, building on the legacy of standards set in projects such as Purple Hayes. Capabilities include:
- Entire unit powered by hydraulic Power Pack
- 285,000 pound upstroke jack capability
- 142,000 pound snub jack capability
- Unit capabilities up to 15,000 PSI
- 10,000 foot/pound rotary table
- Motor Rotary (4) capable of producing 120 RPM
- Integrated hydraulic gallery slip system
- 12-foot stroke length
- Tubing guide capabilities for extreme high pressure applications
- Integrated Milling Clamp
- Drilling Acquisition System (DAS) capable of streaming live drilling parameter data for remote viewing applications, including printable graphed data logs
As lateral lengths surpass 6,500 feet, snubbing has advantages over the use of coiled tubing, such as weight on bit (WOB), debris management issues, and longer plug times typically associated with coil.
DWS snubbing units have the ability to rotate which results in more efficient, well-cleaning capabilities. In addition, they can pull up to 285,000 pounds and push 142,000 pounds, greatly reducing the likelihood of becoming stuck. These units drill out, run tubing and set the packer all in one rig up and have the ability to run tapered strings ranging from 1.9 to 5.5 inches.
Other snubbing advantages include fast trip speeds of approximately 60 joints per hour; single-pick rig overs with primary BOPs; average of 25 to 30 plugs per day; higher flow rates/AVs; and the stick pipe is able to achieve greater ROPs past 6,500 feet.
“Throughout 2017, DWS will have the ability to provide its customers with jointed tubing, well-modeling capabilities to help in the planning processes for future long lateral completion programs,” said Matt Tourigny, Technical Sales Manager at DWS. “These 285K snubbing units have very compact footprints which are capable of mobilizing to small wellsite pads and have the ability to obtain road permits in any areas of the basin.
“At DWS, we continually strive to add to our evolving fleet and industry-leading technology in an effort to push the limits of stick pipe completed laterals that the competition cannot achieve,” he added.
