What is the purpose of managed pressure drilling?
An adaptive drilling method used to precisely control the annular pressure throughout a wellbore. After determining the downhole pressure environment, drillers manage wellbore pressure constrained by the limits of formation properties.
What is MPD in oil and gas?
“Managed Pressure Drilling (MPD) is an adaptive drilling process used to precise- ly control the annular pressure profile throughout the wellbore. The objectives are to ascertain the downhole pressure environment limits and to manage the annular hydraulic pressure profile accordingly.”
What is MPD operation?
The Underbalanced Operations and Managed Pressure Drilling Committee of the International Association of Drill- ing Contractors has defined MPD as “an adaptive drilling process used to pre- cisely control the annular pressure profile throughout the wellbore. MPD techniques may be used to avoid formation influx.
What is underbalanced drilling?
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 then the formation being drilled. As the well is being drilled, formation fluid flows into the wellbore and up to the surface.
What is drilling under pressure?
Drilling Under Pressure is a process used for drilling a hole into a system of flowing pipe without interrupting the flow or leaking its contents. This means that the flowing pipe systems can continue their operations while modifications or maintenance operations are being carried out.
What is gas drilling?
Gas drilling is the process of creating fractures in a natural gas reservoir found beneath the earth’s surface. The reservoir may include crude oil or natural gas. The drilling process is usually carried out by hydraulic fracturing, which involves the insertion of a fracking fluid at high pressure to induce fractures in the rock formation.
