Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)
This report focuses on the detailed planning for drilling an exploratory well in the Molly field, located in the North Sea. The primary goal of this well drilling programme is to safely and efficiently explore the "Carboniferous Siltstone" reservoir at 10000ft TVD, while adhering to environmental regulations. Key themes addressed in the report include:- Selection of the appropriate drilling rig based on operational considerations.
- Estimation of pore and fracture pressure gradients to ensure safe drilling operations.
- Anticipating and mitigating potential drilling challenges based on lithological characteristics.
- Designing a casing scheme that effectively isolates formations and ensures wellbore stability.
- Developing a comprehensive mud and cement program to manage formation pressure and facilitate well completion.
