Paper Number: SPE-202140-MS
...) to control the bottom hole pressure on the well by never switching off the pumps, therefore the wellbore never experiences an Equivalent Static Density(ESD). Through this mechanism, the application of CCS has also been proven to manage bottom hole pressure constantly, which in conjunction with good drilling...

Several multi rate tests and pressure transient analysis were performed to understand asphaltene deposition in the reservoir near wellbore region and away from the well. Asphaltene deposition in the production tubing was also assessed by means of friction...

..., the actual drilling window lay between the wellbore instability and mud losses pressure gradients. Having the bottom hole pressure lower than the wellbore instability pressure would risk collapse of the wellbore, resulting in stuck pipe, or worse, a fishing job and requirement to sidetrack the well. Thus...
