Paper presented at the ADIPEC, November 4–7, 2024
Paper Number: SPE-222742-MS
.... A high-level Managed Pressure Drilling (MPD) strategy was developed, involving the use of a 15.2 ppg mud weight with an Equivalent Circulating Density (ECD) of 16.9 ppg. The plan included performing Dynamic Pore Pressure Tests and MPD Build Up Pressure Tests at the bottom of the Dharuma Formation...

... water zones, mud weight can be increased to 18.5 lbm/gal to prevent influx. Therefore, a high-density cement slurry is required to maintain overbalance during the cementation of the 7-in. liner. The effect of contamination was determined in the laboratory by comparing various concentrations of formation...

.... This makes it challenging to drilling engineers and difficult to balance between natural mud losses across the carbonate formations and weak shale that requires higher mud weight. Adding to these challenges, the limited surface locations in the field, that forces the well design trajectory to be deviated...

... at the surface. Further the continuous mud cap is applied while drilling to maintain the constant bottom hole pressure. However, the mud cap flow rate and mud weight (MW) most of the time are based on local best practices and not supported by any engineering study, for example using 1.5 ppg at the rate of 1.5...

... are considered, which leads to higher propensity for failure. Shale stability tests demonstrated that most of the instabilities identified in the Laffan and Nahr-Umr formations were mechanical in nature. The optimal mud weight is strongly dependent on the well trajectory to account for the plane of weakness...

The safe mud weight window derived from geomechanics provides the basis for mud weight and mud formulation designs that can be continuously optimized to improve wellbore stability and reduce drilling risks. The integrated approach has been applied for 4 horizontal wells in Weiyuan's shale gas...
