SPE/EAGE Workshop on Geohazards
Geohazards are a factor that is considered when planning new wells as well as operating the existing structures, especially offshore.
Geohazards include submarine slides, shallow gas and dissociation of gas hydrates, mud volcanism, steep seafloor slopes, shallow water flow, seismic activities, history of mass transport activity, seafloor expulsion, shallow faulting and waterflow. With activity in shallow water, shallow gas and unconsolidated sediments are a main challenge. With more activity in deeper water both pipeline stability as well as formation stability changes in the form of turbidite currents and quick sedimentation processes that may lead to overpressured formations and dissociation of hydrates will need to be part of the risk mitigation. Additionally, changes in the mechanical state of rocks can seriously impact drilling operations, completion infrastructures, and production performances which can result in unexpected cost and time overruns.
This workshop will present an advanced overview of surface facilities and subsurface related geohazards. Particular attention will be paid to the improvements in geohazard identification, quantification of risk and mitigation, best practices, lessons learnt and technological advancements in handling geohazards and potential impact on existing offshore structure stability in the current challenging environment. Special discussions on wellbore stability and pore pressure predictions will serve as important components of the completion design, whether to avoid sending, or to develop a simulation strategy to enhance production. In addition, the workshop will also review and identify current and future technologies of both shallow water and deepwater.
