What is Underbalanced
Drilling?
Underbalanced drilling or "UBD" is an exploration and production drilling technology for drilling oil and natural gas wells wherein the pressure within the wellbore is intentionally maintained lower than the fluid pressure in the reservoir being drilled.
As the new oil/gas well is being drilled, formation fluids flow into the wellbore and up to the surface. This is the opposite of typical drilling operations where the wellbore is kept at a pressure ABOVE reservoir pressure to prevent a "kick" which occurs when formation fluids (hydrocarbons) enter the well. In a kick, the well is considered "overbalanced" and the invasion of these formation fluids into the wellbore (a kick) and if not shut-in, can lead to a well blowout.

What are Snubbing Services?
"Snubbing Services" with their "snubbing units" are deployed in the Upstream Oil and Gas industry on oil and natural gas wells when "heavy well intervention" is required. "Snubbing" an oil/gas well requires a snubbing unit whereby tubulars can be installed or removed from " live" oil & gas wells operating under reservoir/formation pressure thereby saving time, money and possible damage to the reservoir.
Snubbing services include the following typical applications:
Cementing
Clean-out
CO2 injection
Coiled tubing services
Conventional workovers
Deepen existing wells
Drilling new wells
Fishing
Gravel packing
"Live" well control
Milling
Nitrogen injection
Nitrogen stimulation
Reservoir stimulation
Perforating
Pipeline cleanouts
Pressure control
Removing bridge plugs
Running production tubing
Side tracking
Under-balanced drilling - UBD
Well completion services
Well control & well control services
Wireline services
Finally, another advantage that snubbing units provide include the ability to work on live wells without having to remove the Christmas tree from the wellhead.

NO FOREIGN OIL!
“spending
hundreds and hundreds and hundreds of billions of dollars every year for
oil, much of it from the Middle East, is just about the single stupidest
thing that modern society could possibly do. It’s very difficult to think of anything
more idiotic than that.” ~ R. James Woolsey, Jr., former Director of the CIA
According to R. James Woolsey, for Director of the Central Intelligence Agency, “The basic insight is to realize that global warming, the geopolitics of oil, and warfare in the Persian Gulf are not separate problems — they are aspects of a single problem, the West’s dependence on oil.”
