Instead of waiting for a big rig to become available, surface drilling can start as soon as the pad construction is complete and a permit is in place. A spudder rig can drill the first several thousand feet of the well (depending on state regulations, this depth can vary).
So what does this mean for business?
-Efficiency – using the right resources for the job. By utilizing surface drilling ahead of the big rig you don’t have an expensive large rig waiting on:
- The BOP to be nippled up
- Surface cement to be pumped and set
- Lost circulation issues on the surface hole
- Formation drilling difficulties on the surface hole
- Swapping from fluids and waiting on cleaning tanks
– Decreased cycle time. The surface rig starts the drilling process before a larger rig arrives, letting that larger rig focus on the deep drilling.
- With the surface hole drilled, cased and cemented when the large rig arrives you are cutting back the time the big rig is on location.
-Lower costs. The surface rigs have a footage rate that is predictable for each well regardless of how long it takes to drill. The spread of a large rig for the same time is often much more expensive. A surface rig means:
- No third party casing crew
- Less water usage
- Less water disposal
- No time to swap from water to oil based muds
-Streamlined operations. Pads can be brought on at a quicker pace, saving several days in the drilling process and getting the operator closer to cash flow faster.
Efficiency is the backbone to shale oil, regardless of volatile market conditions, and is a constant driver to our success as an industry. To be the most efficient, utilize surface drilling to get up and running quickly and inexpensively. hosting information . web page speed server hosting info . Sislahornschegal .
