Operational Challenges for Drilling Shallow Water Wells With Dynamically Positioned Rigs


1 Jun 2020

The objective of this presentation is describe challenges for shallow water operations with DP rigs and provide solutions for key design & operational challenges


  • Traditional shallow water wells (water depth of 300 ft-500 ft) are drilled using jackups/ moored rigs. 

  • However dynamically positioned (DP) mobile offshore drilling unit (MODU) rigs are being considered. 

  • Majority of shallow water wells were drilled in early developments of offshore drilling. Plug and abandonment operations of those wells are done using DP vessels due to lack of availability of the original rigs.
