... bottom introduces additional complexities, including pipe movement, fluctuating pump pressures, the absence of Equivalent Circulating Density (ECD) readings at the well's total depth (as the bottom hole assembly is off bottom), and temperature effects. These factors may lead to misinterpretations during...

... pressure cement (MPC) operation carries its own potential challenges, therefore it is vital that a detailed design philosophy is used when leveraging this approach. During managed pressure drilling (MPD) operations, real-time data is received throughout the drilling process (i.e. downhole ECD, pressure...
