PWDa

Pressure While Drilling (PWD) simulation, manipulation and data analysis tool. The PWDa identifies the key phenomena which impacts annular pressure during well drilling of petroleum reservoirs.

PROBLEM

Drilling offshore oil wells is a very expensive and complex process, in which all the efforts must be taken to keep the annular pressure between a minimum pressure (pore pressure) and a maximum pressure (fracture pressure) which define the operational window limits.
Several phenomena impact the bottom hole annular pressures, such as: ineffective hole cleaning, gel breaking when circulation is resumed, drillstring movement (surge and swab), trips, pills displacement, kicks, etc.
The correct interpretation of pressure while drilling (PWD) data is a very powerful toll to identify and prevent these phenomena.
