UnderBalanced Drilling

UBD is in high demand, especially in pressure-depleted formations, but application requires field experience and safe practices.

  • Signa's UBD procedures provide step-by-step operational instructions for your project, including surface equipment diagrams, choke management plans, flow rates, and the ideal fluid type (mud, oil-based fluids, aerated mud, foam, mist, air, etc.).
  • Your well or hole section can be modeled by a professional engineer specific to the downhole limits, including pore pressure, frac gradient and wellbore stability.
  • Our recommendations are based on experience, not equipment sales. Get a no-risk quote or check our MPD/UBD case histories.
