Patrick Horner, VP Engineering, Aqua-Pure Ventures, is a Professional Chemical Engineer registered with APEGGA who has 15
years of experience with Oil and Gas Facility Process Design and Construction, Petro-chemical Plant Operation, and Industrial
Wastewater Treatment. He holds a B.Sc. in Chemical Engineering from the University of Alberta. A key portion of Mr. Horner’s
experience has involved the project management of new technology trials in both petrochemical and wastewater applications.
He was heavily involved in the design and construction of the NOMAD 2000 units and led the development of the gas shale
pre-treatment system. Mr. Horner has extensive knowledge of oilfeld water chemistry and the associated problems with
fouling as well as designing systems to work effectively in high fouling environments.
Performance of SAGD Produced Water Evaporator Designs and Water Tube Boilers
Gerardo Lara - Rentech and Bill Heins - GE Water & Process Technologies
This presentation discusses the operational history of evaporators and drum boilers for SAGD steam production. The
information is based on operational data gathered over the past fve ( 5) years. Also covered are some of the operational
lessons learned during the past fve years and planned improvements and modifcations going forward.
Gerardo Lara is the Western Canada Territory Manager for RENTECH Boiler Systems, from Abilene, Texas. He is an Electrical
Engineer graduated from UANL in Monterrey, Mexico with 20 years of experience in boiler design, engineering and process
operations. He joined Rentech in 2001 as the process equipment chief engineer and he also supervised RENTECH’s feld
service department. In 2008 he transitioned into boiler basic design and sales. Gerardo’s expertise includes all relevant boiler
codes and standards both American and Canadian as well as all the aspects of boiler design and operation, including furnace
and combustion system design, heat transfer, water and steam quality, boiler internal circulation design, pollutant emissions
(NOx, CO) and control systems. He has troubleshot and solved many boiler performance issues during his career.
Bill Heins is the General Manager of the Thermal Products business unit and a produced water evaporator / zero liquid
discharge expert for GE Water & Process Technologies located in Bellevue, Washington. Bill is a chemical engineering
graduate from the University of Wisconsin and has been with GE, formerly RCC, for the past 22 years. Since joining the
company, Bill has worked on the development and implementation of produced water evaporators, zero liquid discharge
systems, Brine Concentrators, and Crystallizers. Bill pioneered the implementation of produced water evaporators and zero
liquid discharge (ZLD) for the Alberta SAGD industry and has led GE in the execution of 18 such projects in Alberta, including
eight in the past two years. Bill also holds numerous patents in heavy oil recovery and produced water evaporation.

Estimating Relative SAGD Production Rates from Static Seismic Data
David Gray - Nexen
Butler’s equation describes the expected rate of a SAGD well pair. Butler’s equation contains key reservoir parameters that,
in recent years, have been estimated from seismic data. Taking these estimates from seismic data and inserting them into
Butler’s equation gives us the ability to assess the relative rates that SAGD well pairs would produce from different parts of
an oil sands reservoir. Furthermore, since seismic data is 3D and contains information between the wells, then a 3D volume
of relative estimated SAGD rates can be produced. This presentation will describe how this can be done using commonly
available pre-stack seismic data and modern seismic attribute techniques.
