Things You Should Know about Drilling Rig

There are many factors that go into choosing the right water well drilling rig. Three core aspects need to be discussed with your manufacturer partner: location, well specifications, and drilling methods.

1. Location

Location covers local laws and regulations for site access with drilling equipment, as well as legal requirements for well construction. It also includes underground and surface drilling conditions. Drill crews must understand the subsurface formations to keep boreholes stable; complex ground conditions may require multiple drilling techniques to finish a well. On-site surface factors such as altitude and extreme hot-cold weather should also be evaluated, since these conditions may influence rig performance.

2. Well specifications

Well specifications define borehole parameters including target diameter and total depth (TD). When selecting a drilling rig, these parameters determine the configuration of compressors or mud pumps to guarantee sufficient flow rate for cuttings removal. Total depth also defines the maximum tubular string weight once target depth is reached. The selected rig must possess adequate pull-back capacity to lift and retrieve full drill-string weight out of the borehole.

3. Drilling methods

Your final drilling method is determined by site location and well-spec data. Based on these conditions you can make technical selections: air drilling or mud drilling, rotary drilling, DTH hammer drilling, cable-tool drilling or hydraulic rotary drilling. These choices further define drill-string assembly and drill-bit types.

After you clarify all working requirements for field operation, you can select a drilling rig with good adaptability and flexibility.

What are some common oversights that customers make when choosing a rig?

Many buyers neglect future business expansion possibilities. A flexible multi-purpose rig allows you to take on diversified jobs when core business slows down. Besides performance parameters, you should also evaluate the manufacturer’s after-sales support system and pay attention to the rig’s resale value.

What is the potential impact of a multi-purpose rig?

Multi-functional drilling rigs broaden your available business scope. You can carry out conventional drilling one day, then switch to reverse-circulation or core-drilling operations the next day. Owning one multi-purpose unit reduces total-cost-of-ownership. Instead of deploying an RC rig then removing it to bring in a separate coring rig, you stay on the same borehole and finish full-hole sequences by switching between RC and coring modes.
