02 EOR Screening and its Comprehensive Incremental Value
Session Chairpersons Eric Delamaide, IFP Canada; Lirio Quintero, Baker Hughes a GE company

Screening is the first step in the long road to a successful EOR project. Basic screening can range from the very simple - reviewing lists of screening criteria established by several authors – to the more complex involving dedicated software. Yet, even these methods suffer from weaknesses, such as the fact that parameters are often considered in isolation, and that true geological complexity cannot be considered. This session will focus on identifying the issues for screening and the potential ways they could be improved.

Water quality for waterflooding and EOR is a major industry issue accounting for significant technical, economic, environmental and health impacts. The sourcing and/or treatment of the utilized water can determine the success of projects around the globe. In this session, we will be discussing the requirements, economics, technical, and scientific aspects of water utilization to guarantee the realization of industry projects.

04 Business Case: the Need to do a Full Field Commercial Evaluation
Session Chairpersons Carlos Glandt, Consultant; Celso Branco, Petrobras; Eugenio Ferrigno, YPF

This session will address the need to have a de-risked robust business case to embark in an EOR Pilot/Large scale project.  This implies building a spectrum of production forecasts covering all project key uncertainties leading to a sound economic analysis. Typical EOR projects are mounted on mature waterfloods with abundant geological and production data that provide a fairly well calibrated simulation model. Simulation results will be impacted by geological heterogeneities, grid dimension, relative permeability curves, fluid viscosities, and many others. Early simulated sensitivities to these variables are key to focus data acquisition and validation at both, laboratory and field level. The session will cover simulation studies, risk analysis, economic impact posed by wells and facilities conditions, as well as the need for tax and fiscal incentives. A well-grounded commercial business case that ranks against other production alternatives should be the starting point to embark in the multimillion-dollar investment required for field pilots. A successful production pilot will unlock the promise of EOR incremental reserves.

05 Lower Cost Wells and Modular Facilities
Session Chairpersons Francisco Francilmar Fernandes, Petrorio; Andres Lopez Gibson, YPF

In order to be selected for execution, EOR projects need to achieve better KPIs than their alternatives. Knowing that time and money are two important leverages to improve project performance, this session will focus on new technologies and methodologies involving well design & equipment, modularity and efficiency advances in facilities & operations that lower development and lifting costs along the projects, as well as on ways to improve EOR timing, bring it up front in a fields development and/or reducing its development time.

06 Current and Emerging EOR Technologies, and Challenges with Existing Technologies
Session Chairpersons Cesar Patiño, Ecopetrol; Pallav Sarma, Tachyus

This session will cover the emerging technologies that can help improve operational efficiency and economics of EOR projects, including applications of EOR to unconventionals, new materials, methodologies and processes for EOR, and applications of surveillance, modeling, simulation and optimization. It will look at advances in surveillance techniques and IoT for better and smarter acquisition of data, and how this data can be used to the fullest extent via data science and machine learning methods and their applications to EOR projects, advances in modeling and simulations of EOR physics, and approaches that combine these seemingly disparate fields. It also aims to present insights on applications of existing modeling approaches for EOR and lessons learnt. Finally, it aims to explore new materials and processes for EOR, and emerging EOR technologies for shale, such as huff-and-puff, with emphasis on modeling, implementation and case studies.

07 Pilot Design
Session Chairpersons Jose Luis Massaferro, YPF; Carlos Glandt, Consultant; Gaston Fondevila, Grupo CAPSA

The proper pilot design is at the center of a well-executed commercial development plan. The discussion is driven by the clear understanding of the objectives of the pilot, i.e., the key risk factors the pilot would help us quantify.  The expansion into a commercial venture requires in all cases satisfactory results of a production “oil-in-the-tank” pilot in a confined setting. This is a multipattern arrangement costly in time and company resources.This session will address a) the piloting steps needed before we design and commence the final production pilot and b) the design options of “low cost” oil-in-the-tank pilots to provide unambiguous results required for a commercial expansion decision. Field cases will be most valuable. Illustration of salient topics of this session are: a - Injectivity of the EOR fluids under matrix and fracture conditions, b- Communication and fly times between injectors and surrounding producers, c - Mechanisms for oil bank propagation and chemical consumption by adsorption and other losses, d- Polymer viscosity degradation, e – Design and execution of an Oil-in-the-tank pilot in a fully confined arrangement.

08 Field Experiences
Session Chairpersons Rodrigo Dalle Fiore, Ecopetrol; Andres Lopez Gibson, YPF

After screening for candidate fields, studying the reservoirs to select a suitable one for EOR, performing extended lab testing on their fluids and cores, and after obtaining corporate approval, field pilots and their subsequent expansions are the firsthand experiences. Unexpected situations will occur and must be documented if we want EOR to become a reality.

This session will show how EOR is done at the field. It will present common problems and lessons learned, aiming to obtain monitoring best-practices and de-risking strategies to guarantee future development.
