UBD frequency has decreased from a decade ago, but it’s still utilized around the globe to drill pressure-depleted formations and reduce formation damage. Signa is no stranger to the technique: In the 1980s, CEO Rick Stone helped develop UBD in the Pearsall Field of Texas. And then in the 1990s, Signa expanded the technique to pioneer MudCap Drilling in the sour-gas, cavernous formations of Kazakhstan, the Arabian Gulf, South America, and the Caspian Sea. If you would like to discover how UBD can benefit your campaign, our engineers can explain all the details. Or we can design a UBD program specific to your well, including surface equipment diagrams, choke management plans, flow rates, and fluid type (mud, oil-based fluids, aerated mud, foam, mist, air, etc.).
