Students at Susquehanna County Career & Technology Center were able to use their skills to manufacture a training tool for Cabot Oil & Gas.
As Cabot Oil and Gas develops new technology to further increase productivity of its wells, the close relationship with the Susquehanna County Career and Technology Center (SCCTC) at the Elk Lake High School Campus has resulted once again in a solution to the company’s need for a complex training tool – this time for its employees.
As the pressure in older wells decreases, it becomes more difficult to force excess water to the surface. As the fluid builds up, gas production is adversely affected. The traditional remedy has been to halt production once per day or so and inject detergents to create suds to bring the fluid back up, Cabot production foreman Ryan Bennett explained, but this technique can become inefficient over time.
Another way to handle the fluid buildup is a device, called a “plunger lift,” which is dropped to the bottom of the tubing in the well, where it makes contact with a spring. The pressure in the well casing increases until the plunger rises to the top, bringing the fluid with it. “Once installed, the unit runs continuously, and all you have to do is set the parameters through an application to manage the device,” Bennett offered.
The plunger lift is universal in that it’s implementable on most existing wells pads, but the productivity of wells can vary depending on various stages of production, which influences when a company might install them. Therefore, a mock-up of the plunger lift unit was needed to help Cabot employees see the workings from the inside out.
Cabot SCADA/measurement foreman Adam Vogt made a call to SCCTC welding instructor Ray Ingaglio, who has overseen the fabrication of other instructional tools on Cabot’s behalf for use at the Lackawanna College School of Petroleum and Natural Gas. Bennett followed up with an email providing the details of what Cabot needed.
“Ray let us know that they had the capability of cutting some of this stuff open for us,” Bennett related. “They also did some of the welding at their shop.”
“About a half dozen students worked on it,” said Ingaglio. Tasks included cutting a base for the unit, dissecting the valve, and assembling and disassembling it until all the parts were functional. The project provided opportunities for the students to try a number of processes that were new to them, including developing a program to cut out the base embossed with the letters SCCTC with a computer-controlled plasma cutter.
On Cabot’s end, the SCADA team was busy building the companion piece, an RTU (remote terminal unit) that can be specifically configured with the HMI (human interface machine) on each well pad. “The rest of it is a series of control modules and relays that actuate automated valves to let the plunger drop and pull the plunger up,” he explained.
The metal work rendered by the SCCTC students provides the internal view of the mechanism, which Ingaglio maintained is an invaluable opportunity for the youths. “It gave them more of an idea of what goes on the well pads,” he stated, “including the types of lubricants they use.”
While they have collaborated on a number of initiatives, Vogt suggested that the plunger lift training unit may be the most complicated and significant project to date on which SCCTC has taken the lead. Cabot will realize substantial savings in time once the artificial lifts are in operation.
According to Cabot external affairs coordinator Bill desRosiers, increasing the company’s efficiency in the field will help it achieve an increase in production from two to three billion cubic feet (BCF) per day, the projected volume of natural gas needed by next year to fill the Atlantic Sunrise Pipeline and two new power plants at the Lackawanna Energy Center in Jessup and Moxie Freedom Power Generation facility in Berwick.
“All those wells have to be managed, plus the new ones that are being drilled and brought on line,” desRosiers noted. “These innovations will allow for the field to meet its daily goals.”
In the meantime, the recent project is indicative of a relationship with a relatively rural school district that provides SCCTC with materials, funding, and connections that many larger schools cannot offer. Among the trade-offs is a growing, professionally-trained, homegrown workforce.
“To get an idea of what’s involved in the gas industry is good because many of them are thinking about what they are going to do after school,” Ingaglio remarked. “I had two students who passed their API test for pipe welding last year. One went to work as a pipeline welder for Linde, and the other was accepted in the boiler makers union. That is very rare for an 18- or 19-year-old kid.”
Bennett and other Cabot employees have served as judges for students seeking National Occupational Competency Testing Institute (NOCTI) certification as welders. “That’s a big deal,” Ingaglio related. “We can’t grade the kids ourselves, and most people don’t want to drive to (what they perceive as) the middle of nowhere and give up a day’s work.”
“It is representative of the Susquehanna County Career & Technology Center and their willingness to work with the gas industry because they recognize the career opportunities,” said desRosiers, who sits on the board of the tech school’s welding department. ”Being so close to the play, it makes sense for them to incorporate it as much as they can into their curriculum.”
“If the kids apply themselves here, they can leave with many welding certifications. It doesn’t cost them anything,” Ingaglio explained. “They can fail it three or four times here before they pass it, and they don’t have to worry about the price.” Cabot’s contribution to the Community Foundation helps to purchase tools and welding jackets – a $350 value – for qualifying students, he added. “That relieves a big financial burden.”
