The south Caspian basin is unique in its combination of extremely rapid burial rates, complex stratigraphy, and tectonic setting.
This leads to a plethora of shallow hazards, pore pressure, and geomechanics related challenges for drilling, completions, surface facility location, and reservoir management.
Recent drilling activities within the Caspian basin have seen numerous challenges. Deep and extremely high pressure (narrow drilling margin) gas wells present considerable challenges in terms of managing losses and gains.
In close proximity, but with very different challenges, is the large-scale development of the giant Azeri-Chirag-Guneshli oil field. Since the onset of production in the field, the effects of depletion have added an additional layer of complexity.
The ability to predict and mitigate shallow hazard, pore pressure/fracture gradient (PPFG), and wellbore stability issues, and to understand the effects of reservoir depletion on stress state, and fracture gradient is key to the successful drilling, well completions, and reservoir management of fields.
In this workshop, we will:
- Share knowledge and experiences in the area of shallow hazards, geomechanics, and PPFG delivery, and discuss how application has added value in similar settings
- View examples of data acquisition and methods of analysis which have proven to enhance the predictability and understanding of shallow hazards, geomechanics, and PPFG in similar settings
- Discuss drilling and completions best practices to tackle the aforementioned issues in the basin
- Experience emerging technology that can be applied to tackle the issues: real-time monitoring while drilling, managing the pressure window, and permanent surveillance
