Workshop and Technical Tour
IOR 2019 offers a Workshop and a Technical Tour after the conference on Thursday 11 April 2019.
All delegates who are interested in the workshop or the technical tour should register together with the conference registration.
Workshop: "Global deployment of chemical EOR: challenges and operational issues"
10:00 - 16:30 hrs
Location: Le Palais Beaumont
Chemical Enhanced Oil Recovery (EOR) has been a long-term area of interest for academia and industry. Results of these efforts are presented at symposia like IOR2019. The ultimate goal for these efforts is field implementation to deliver incremental oil, as also reflected by the theme of the symposium: The workshop complements the technical programme of the Symposium by providing participants insights in what it takes to implement and operate chemical recovery schemes.
A vast number of chemical EOR pilots are under design, in execution, or have been completed. Pilots generally represent the first reality check for a larger scale commercial implementation: during several months to years, chemicals need to be brought to the field, mixed consistently, and injected while produced fluids are carefully monitored to identify and quantify the “EOR oil”. Evaluations of completed pilots provide an excellent learning opportunity for people who are currently designing or implementing pilots.
Commercial scale polymer EOR projects are successfully operated in different onshore locations globally: CNPC in the Daqing region in north-eastern China, Cairn in India, PDO in southern Oman, YPF in the Grimbeek field in Argentina, Canadian Natural Resources at Pelican Lake, and OMV in the Matzen field in Austria. What was required to make these projects happen and what is the experience in operating these projects for many years?
Based on the success of the polymer floods CNPC, Cairn, PDO, and YPF are in the process of extending or following the polymer floods with (Alkaline) Surfactant Polymer (ASP) floods. CNPC has most experience in terms of number of pilots executed while Cairn and PDO have completed technically successful pilots. SPD has also completed a technically successful ASP pilot in the West-Salym field in Western Siberia and is evaluating the next steps towards larger scale implementation. GazpromNeft, one of SPD’s shareholders is evaluating how the West-Salym ASP pilot results can be translated to their other fields in the West-Siberian basin. What is required to extend or convert polymer floods into ASP floods and how were pilot results to understand the requirements?
The challenges for implementing chemical EOR offshore are potentially even greater than onshore. Inter-well distances are larger, it is routine practice to inject sea-water or re-inject produced water, resulting in polymer injection brines that are highly saline and potentially contain contaminants, EOR polymers are highly shear susceptible and while there is plenty of space onshore which allows facilities such as chokes to be by-passed, this is almost impossible on offshore sub-sea templates. Offshore, there can be extreme weather conditions which have led to renewed interest in liquid emulsion polymers and their ease of handling over powder products. Chevron has completed a successful polymer pilot in the Captain field in the North Sea. Equinor is testing polymer injection in the Peregrino field offshore Brazil since January 2018.
In the workshop different operators will share their experiences in what it takes to move chemical EOR from concept to commercial reality, how to operate chemical floods, and how these experiences have been incorporated in plans to expand the flood or to implement ASP. At the end of the workshop several chemical suppliers and service providers will provide insights in their role to facilitate global deployment of Chemical EOR.
Technical Tour: Visit to the Physical Measurements Centre / Total E&P Alternative Subsurface Data
09:00 - 12:30 hrs
Location: Artigueloutan (15min from the centre of Pau)
Maximum attendance: 30 participants
This tour offers participants the unique opportunity to visit the brand new Physical Measurements Centre/ Total E&P Alternative Subsurface Data. This centre opened in spring
2018 in the vicinity of Pau for well logging tools calibration using scale standard rock labs. For more information on the centre visit www.tep-add.com.
