Managed pressure drilling pdf. Customer Guide to Managed Pressure Drilling PRESSURE UNCERTAINTY In the industry today there is uncertainty in understanding the pressure regimes in which we operate. The MPD system also can be divided into two major categories. Managed Pressure Drilling MPD is an adaptive process used to more precisely control the annular pressure profile throughout the wellbore while drilling.

The aim of MPD is to improve the drillability of a well by alleviating drilling issues that can arise. When bottom hole pressure BHP could be controlled and held just above the highest pore pressure a safe operating environment could be created to allow. Managed Pressure Drilling MPD is an advanced form of primary well control typically employing a closed pressurizable fluid syst em th at all ows grea t er an d more prec ise control of the wellbore pressure profile than mud wei ght and mud p um p rate ad j ustments alone.

To mitigate the narrow window in the overpressure zone for drilling the next exploration well in the same field Drilling Operator seek the solution in Managed Pressure Drilling MPD. With managed pressure drilling Source. One where the human has to control the MPD.

The objectives are to ascertain the downhole pressure environment limits and to manage the annular hydraulic pressure profile accordingly. IADCs definition is that MPD is an adaptive drilling process used to precisely control the annular pressure profile throughout. Now it is also a performance-enhancing solution.

Managed Pressure Drilling MPD techniques have proven to be cost-effective reliable and safe when drilling difficult onshore wells as well as when drilling from mobile offshore drilling units MODU with a surface BOP. A typical managed pressure drilling system Muir 2008 p9 20 HOW MPD WORKS The basic technique in MPD is the ability to manipulate the Bottom Hole. Managed pressure drilling is a new technology that uses tools similar to those of UBD to better control pressure variations while drilling a well.

Managed pressure drilling is a developing technology that is promising to reduce costs and improve efficiencies particularly in difficult wells. Risk Management With all MPD operations a detailed risk assessment as well as a HAZID and HAZOP should be carried out with the rig crew supervisors and the relevant service providers and operator staff.
