Project Scope:
Saudi Aramco is acquiring multiple mobile trailer package equipment for the underbalanced drilling system to be utilized in different drilling locations.
Process:
Underbalanced drilling, or UBD, is a procedure used to drill oil and gas wells where the pressure in the wellbore is kept lower than the static pressure of the formation being drilled. As the well is being drilled, formation fluid flows into the wellbore and up to the surface. This is the opposite of the usual situation, where the wellbore is kept at a pressure above the formation to prevent formation fluid entering the well. In such a conventional “overbalanced” well, the invasion of fluid is considered a kick, and if the well is not shut-in it can lead to a blowout, a dangerous situation. In underbalanced drilling, however, there is a “rotating head” at the surface – essentially a seal that diverts produced fluids to a separator while allowing the drill string to continue rotating.
Our Solution:
Rockwell redundant ControlLogix non-SIL PCS, and Rockwell redundant ControlLogix SIL-2 ESD system.
