In order to solve low degree of work over automation, labor-intensive job dangerous, poor working environment issues, Shengji has developed a series of mechanical work over system, including workover automatic system, minor workover automatic system and snubbing operation equipment.

Oil well workover is a high-tech, high-risk work. The conventional oilfield workover rig has problems such complicated operating procedures and high labor intensity. Shengji, in cooperation with the Shengli Drilling Corporation, have designed an oilfield workover rig automation system.

The oilfield automatic workover rig has a high degree of automation adopting modular integration and advanced robot closed-loop control technology. It functions as self-diagnosis, leakage and short circuit protection and fault alarming, etc. It has remote monitoring capability.

The automatic workover rig greatly increases the automation of workover operations, reduces the number of operators, decreases workers’ labor intensity. The technology is advanced, safe and reliable.

Drill floor (#21) is the area on the rig where the tools are located to make the connections of the drill pipe, bottom hole assembly, tools and bit. It is considered the main area where work is performed.

Setback (#17) is a part of the drill floor (#21) where the stands of drill pipe are stood upright. It is typically made of a metal frame structure with large wooden beams situated within it. The wood helps to protect the end of the drill pipe.

Stand (#16) is a section of 2 or 3 joints of drill pipe connected and stood upright in the derrick. When they are pulled out of the hole, instead of laying down each joint of drill pipe, 2 or 3 joints are left connected and stood in the derrick to save time.

For most operators, improving profitability on their wells is an ongoing battle between getting the right equipment, making the job easier, and keeping a strict eye on the bottom line.

A perfect example of this is that many operators go with a full-size drilling rig for surface interval drilling because it is more convenient. Often, they are already engaged with the service provider and the equipment is already on site — so it seems like this is the most cost-effective decision. In the end, though, operators end up paying more in fuel and personnel costs, and increasing their HSE risks, with this option.

Full-size rigs are made for constructing wells with total depths over 20,000 feet. These are enormous machines for enormous jobs. As a result, they have an enormous footprint in terms of costs and risks. When drilling surface intervals and running surface casing, a full-size rig is not the right equipment for the job. While it may seem more effective at the time, a surface drilling rig or spudder rig is the better choice.

Less fuel consumption and lower fuel costs: Surface drilling rigs are highly engineered for surface drilling and running surface casing. They are smaller in size as compared to full-size rigs, which means they use a lot less fuel. To be exact, spudder rigs actually burn up to 50% less diesel compared to full-size rigs, which means they also cost about 50% less to operate.

Equipment optimization:When operators use full-size rigs for surface drilling and running surface casing, they aren’t able to reserve the machines for their intended use. If operators have a separate spudder rig, then the full-size rigs can be used for applications better suited for them, reducing overall operating costs.

Lower personnel costs: Typically, a full-size rig requires a crew of 16 people to operate, while a top hole rig only has a crew of nine. With a lower personnel count, there are lower payroll costs. Not only that, the costs for personnel transportation are lower as well, in addition to the HSE risks.

Safer work environment: With a full-size rig, operators must switch between mud systems, which means that the crew has to mix different muds on location. Handling more fluids increases the chances of spills, which is detrimental to the environment and to the crew. A top hole drilling rig uses a closed-loop mud system, so there is no need to switch between different mud systems or handle different types of mud on location.

A smaller, fit-for-purpose preset surface drilling rig is a more economical choice than a full-size rig when it comes to drilling surface intervals and running preset surface casing.

A differentiating factor between EnerCorp’s surface drilling rigs and our competitors is the customized casing running tools (CRT) that enable us to be faster and more cost effective than other service providers.

Fit-for-purpose equipment: Our CRT’s are specifically designed for our RD20 XC rigs. This allows for the casing to be torqued up to proper torque specs per the casing manufacturer’s specifications.

Better processes:Competitors use alternative methods to run casing: Wishbone style casing elevators. In this process, a tool is used to run casing on our competitors rigs that does not keep the casing full and requires a swedge to be rigged up to fill it. There is far greater exposure and risk to the man in the basket on a board suspended from the derrick. Plus, dry casing run with this method is far less efficient because each joint needs to be filled via the swedge on top of the casing, taking more time. The Wishbone is a far more dangerous method as sometimes it does not latch correctly and can cause the casing to be unsettled during the run.

When working with EnerCorp, operators not only get the benefits of using a surface drilling rig, but also the additional advantages of using fit-for-purpose equipment that is highly optimized as compared to competitor options.
