Technical Agenda

Wednesday, 20 August, 0830-1000

Session I: Subsurface Challenges

Chairs: Sander Suicmez, Maersk Oil; Jeffrey Miller, Statoil

As the industry moves into deeper waters, understanding and managing the subsurface risks becomes even more challenging for IOR/EOR due to cost drivers and lack of data. Reservoir characterization and modeling are challenging because of seismic limitations and sparse well information, dynamic performance is often unknown prior to development, well type and placement is more critical due to compartmentalization risks, and production technology is challenging because of remote subsea wells and design limitations in HPHT environment. Smart and efficient development strategies are needed to mitigate these risks. In this session we will discuss how the industry is addressing these uncertainties as well as challenges related to injectivity, sweep efficiency and validation of incremental oil recovery in existing IOR/EOR projects.


Session II: Facilities/Wells – Challenges and Innovative Solutions

Chairs: Fady Chaban, ConocoPhillips; Steve Anderson, Kinder Morgan

With increasing interest in development of offshore assets by using improved and/or enhanced oil recovery techniques, the adoption of the right technology is essential to overcome these challenges. This session aims to showcase advanced and innovative solutions for wells and facilities which could meet the demanding requirements of IOR/EOR processes, specifically from integrated engineering activities, well design, subsea, and surface facilities.


Session III: Integrated Modeling

Chairs: Reza Fassihi, BHP Billiton; Torsten Clemens, OMV Exploration & Production GmbH

It is important to have access to robust integrated asset modeling (IAM) for IOR/EOR application due to severe limitations in an offshore environment such as wide well spacing, limited well intervention, and extreme operating conditions. IAMs carry out diagnostic tests for surveillance in addition to running production optimization especially when we are dealing with multiphase flow in our subsea lines. In this session, we will discuss the required tools and methods for IAM and present a few cases as best practice examples.


Session IV: Waterflooding, Low Salinity Flooding, and Chemical EOR – Field Examples

Chairs: Andreas Matzakos, Shell International E&P; Lisa Henthorne, Water Standard

Water-based IOR/EOR methods offer significant potential to increase offshore oil production. Waterfloods have the most accumulated operating experience in offshore environments. However, deployment of low salinity, polymer, alkaline or surfactant EOR is sparse offshore, and challenges are also significant. Some challenges are related to surface (like supply logistics, facilities footprint, and weight) and some are related to subsurface (uncertainty in field connectivity and permeability distribution, and long well spacing)  Lessons learned from application of offshore waterflood or chemical EOR in full field projects, trials, pilots, or field studies in post-feasibility stage will be shared. The session aspires to stimulate discussion on offshore opportunities of low salinity flooding and chemical EOR for the purpose of exploring ways to overcome these challenges.

Thursday, 21 August, 0800-0930           

Session V: Gas Injection/Water Alternating Gas EOR – Field Examples

Chairs: Dengen Zhou, Chevron; Fernando Rodriguez de la Garza, PEMEX Petróleos Mexicanos

Onshore gas injections are proven EOR processes contributing about 400 MBOPD to US domestic oil production. The number of offshore gas injection projects has been increasing in the last decade in all major oil producing regions from the Northsea to the Gulf of Mexico to West Africa. This session will focus on field examples of both onshore and offshore gas injection designs illustrating the key technical and commercial hurdles needed to make gas injection projects economical. Presenters will share field cases showcasing their operational challenges and best practices of gas EOR reservoir management generating discussions on potential technical and operational challenges for gas EOR in deepwater environments.


Session VI: Commercial/Project Execution and Economics Challenges

Chairs: Namit Jaiswal, Shell International E&P; Jorge Garduno, GATE

Offshore Projects are capital intensive and inherently risky, especially when dealing in deepwater environments. The justification to a project team of allocating budget and resources into the original design or into an existing design for IOR/EOR can be very challenging. IOR/EOR can result in accelerated volumes or incremental recoveries or may have commercial synergy to available gas. All these scenario need to be evaluated to understand true economic viability. This session will focus on impact IOR/EOR may have on projects, field development, and ultimately the economics of the development.


Session VII: Enabling Technologies for Offshore IOR/EOR Application

Chairs: Gary Jerauld, BP; Robin Ozah, Shell International E&P

IOR/EOR technologies currently deployed, under development, and in the trial phase will be presented. Discussion and sharing of results of implementation, success and failures as well as challenges faced is the goal of this session. The role of technology in IOR/EOR in offshore and deepwater environments will be addressed.


Session VIII: Interactive Session – Way to the Future

Chairs: Deniz Dindoruk, Shell International E&P; Steve Anderson, Kinder Morgan

In this session we will break into discussion groups based on the previously identified themes. Each individual workgroup will summarize their learnings and their views on the way forward. The session will end with a plenary discussion on individual group findings focusing on future IOR/EOR technology applications in offshore environments.
