29 – 31 May 2013

Manta, Ecuador | Hotel Oro Verde Hotel Manta

Technical Agenda

Wednesday, 29 May,  0800–0830

Opening and Welcome Remarks

0830–0900

Background and Expectations/ Framework/Definitions

Session Chairperson: Jose G. Flores, Schlumberger

The objective of the opening session is first to recap what is happening in Ecuador and the Latinamerican region in terms of EOR development, projects, trends, and outlook. What are the major players in the region and others doing? What is being observed in terms of technology availability and the main challenges ahead.

Second, we will set up the framework for this ATW, including basic definitions, what and when a project can be considered successful, are technical answers all that is required in order to have a commercial EOR implementation. Lastly, the expectations and deliverables for this workshop will be outlined with the help of the audience.

0900–1030

Session I: Icebreaker Geology, and Reservoir Challenges

Session Chairperson: Francisco López, Petroamazonas

While the geographical scope of the workshop is broad, it is important to set up a geological working framework to initiate discussions, as such the general geological aspects of the Putumayo-East-Marañon basin will be outlined, with particular focus on the essential geological, reservoir, and operational variables that challenge a successful EOR implementation.

1100–1230

Session II: Initial Task Concept, Screening, Reservoir Studies – Part 1

Session Chairperson: Edgar Rangel Germán, CNH Mexico

EOR projects typically start with a screening of processes and a reservoir study to explore options, that usually takes from one to two years. The fundamental questions here are, what should be the most efficient and effective way to launch a successful EOR project, are the numerical models built for field development sufficiently detailed to design and operate EOR processes, what is the current oil saturation, how to deal with reservoir heterogeneity, how to mitigate reservoir uncertainty, what is required in terms of additional reservoir information and characterization work?

In this session we will have two presenters with the same or perhaps different views and approaches to the same challenge.

1400–1530

Session III: Initial Task Lab, Tracers – Part 2

Session Chair: Ramón Correa, AGIP

This session will focus on conventional and new technology lab tests, what are the minimum requirements? What is the best timing to initiate lab work? What can be done in parallel to accelerate the EOR process?

Are some of the questions to answer by the experts in this session. Will also cover single well tracer tests and multi well tracers, showing relevant examples.

1600–1730

Session IV: WaterFlooding, Low Salinity WaterFlooding

Session Chair: Francisco Porturas, Halliburton

While the classification of waterflooding as an EOR process is questioned by some, what is clear to all is that waterflooding can increase production and the recovery factor. In this session we will discuss the benefit of waterflooding, and its significant as a starting point before more elaborated EOR processes are even considered. The state-of-the-art in low-salinity waterflooding will also be addressed, followed by application examples. Ample discussion among experts and participants is anticipated.

Thursday, 30 May, 0800–1000

Session V: Chemical EOR

Session Chairperson: Fernando Rodriguez De La Garza, PEMEX

Chemical EOR offers a tremendous potential to increase production and the recovery factor from many of the fields in the region, in both clastics and carbonates reservoir environments. While some of the processes are fairly simple and can be put in place economically, many reservoirs and fluid environments require more elaborate chemical processes, that posses significant technical and operational challenges. The main advantages and challenges will be discussed by the experts in this session followed by worldwide and regional application examples.

1030–1130

Session VI: Gas (HG, CO2)/WAG EOR

Session Chairperson: Fernando Rodriguez De La Garza, PEMEX

Gas dominated EOR processes have proved to be highly valuable to increase the recovery factor in a variety of reservoir environments, however, there is a variety of challenges related to the availability of the source gas and surface installations. The specific challenges, target reservoirs and fluid systems, and relevant operational aspects will be discussed in this session, followed by application examples.

1130–1230

Session VII: Thermal EOR

Session Chairperson: José Luis Bashbush, Schlumberger

Thermal EOR are the most widely used processes due to its evident benefit and relative simplicity; however, its applicability is generally restricted to highly viscosity oils, sandstone reservoirs and shallow depths. Advances in technology, to discuss in this section, may broaden the applicability of thermal processes to lighter oils, naturally fractured, and deeper reservoirs.

1400–1500

Session VIII: The EOR Pilot

Session Chairperson: Italo Cedeño, Andes Petroleum

The pilot will confirm the viability of the EOR process at a reduced field scale, however, EOR pilot implementation brings a number of practical challenges to the classical E&P organization, e.g., to put together a new set of entities, components, and operating company workflows. What are the key lessons learned by the experts, what are the main technical and operational challenges, what can be optimized, what are the key process variables to monitor, and when to start and to end the pilot, are some of the key questions to be covered in this session.

1500–1600

Session IX: Full Field Implementation

Session Chairperson: Jose Luis Ziritt, AIHE

Having a successful pilot is the “green light” for a full-field implementation. However, is a full-field EOR implementation merely the addition of a large number of pilots, what are the essential components for a successful, technical and economical, field implementation, what are the variables to monitor over the life of the project, is the technology available, what would be a well-balanced set of key-performance-indicators to follow-up the project, how long should the project last, is there additional reservoir life after a successful EOR implementation, are some of the questions to address by the experts in this session. A very dynamic question-and-answer session is anticipated.

1630–1730

Session X: Reserves

Session Chairperson: Edgar Rangel Germán, CNH Mexico

So far, we have concentrated on the technical components and key challenges in EOR projects and processes; however, it is necessary to identify the key managerial drivers to ensure successful and timely commercial projects.

Friday, 31 May, 0830–0930

Session XI: Managerial Framework

Session Chairperson: Ricardo Jorquera, Halliburton

So far, we have concentrated on the technical components and key challenges in EOR projects and processes; however, it is necessary to identify the key managerial drivers to ensure successful and timely commercial projects. This session will open eyes on the managerial side of EOR.

0930–1000

Summary

Session Chairperson: Ramón Correa, AGIP

Summary of the workshop in preparation for the Panel.

1030–1200

Session XII: Panel: EOR The Next Step: Technical, Managerial, Regulatory, Academia, Human Resources

Session Chairperson: José G Flores, Schlumberger

The closing panel will focus on EOR moving forward. The hydrocarbon industry has profound global implications, and it is evident that the EOR projects and processes will be essential elements in the future of our industry. Starting with what we captured from the technical and managerial sessions of this workshop, the panelists will present their expectations and specific needs, from all the posible angles, including technical, managerial, business, educational, research and development, regulatory, environmental, and governmental. What is required in the short, medium and long terms to ensure a sufficient number of commercial EOR projects in the region will be the question to ask.

1200–1230
