Come to the SPE GCS PF&C Workshop and learn how operators have improved oil recovery from existing subsea wells.  Understand the value of subsea boosting or subsea separation when applied to subsea tie-backs and hear about the technical risks and barriers to subsea seawater injection systems, multiphase boosting and separation.  Hear how open water well intervention techniques can improve production rates and recovery.

 

Crude oil development and production in oil reservoirs can include up to three distinct phases: primary, secondary, and tertiary (or enhanced) recovery. During primary recovery, the natural energy of the reservoir drives oil into the wellbore which brings the oil to the surface. Problem is only about 10 percent of a reservoir's original oil in place is typically produced during primary recovery.   Secondary recovery techniques are generally characterized by injecting water or gas to displace oil and drive it to a production wellbore, resulting in the recovery of 20 to 40 percent of the original oil in place.

 

Artificial lift techniques (such as pumps and gas-lift) can greatly improve this and can be applied in Primary or Secondary phase.  In addition,  innovative mudline separation and boosting techniques are now being deployed globally to enable and enhance recovery from ever deeper and ever longer tie back subsea production.  Moreover, the reservoir can be encouraged to give up additional reserves through well interventions which include re-entry drilling/sidetracking, acid stimulations/fracs, re-perforating etc.  These IOR techniques are well known and frequently applied on land and offshore but rarely applied to subsea reservoirs due to high rig costs and limited rig availability. 

 

The purpose of this Workshop is to bring to the attention of the Gulf Coast membership the various technologies that have been applied or will shortly be applied to increase oil recovery in subsea wells.  In some cases it will be shown how application of artificial lift techniques have taken stranded reserves and made exploitation economical.  This workshop  provides 'real life' examples of initial or retrofit deployments of a range of novel technologies to increase ultimate recovery from subsea assets worldwide.

 

 

 

The workshop maximizes the exchange of ideas among attendees and presenters.  Copies of presentations will be made available to attendees if author consents.  Members of the press are excluded.
