8th International Acid Gas Injection Symposium, 24th -27th September 2019, Ramada Plaza Downtown Calgary, Alberta, Canada


Coming Events

AGIS VIII (AGIS8 Brochure)

8th International Acid Gas Injection Symposium

Time: 24th - 28th September 2019

Location: Ramada Plaza Downtown Calgary, Calgary  Alberta, Canada

Topic: International Acid Gas Injection Symposium is a symposium on acid gas injection which will discuss all processes related to the injection of acid gases – AGI, CO2 EOR, rich gas injection EOR and CCS. All of these processes share common aspects and there are synergies that can be exploited from the more mature processes (EOR) to the emerging processes (CCS).


All attendees included registered spouses at the Acid Gas Injection Symposium VIII are invited to the evening reception on the evening of  24th September 2019 from 7:00 pm to 10:00 pm, which is generously sponsored by Gas Liquids Engineering. Please join us for a drink some finger food and a chance to mingle with others.

The Evening Reception is included as a part of the registration package so all are encouraged to attend.

Location: Second floor of Ramada Plaza Downtown Calgary

Address: 708 8 Ave SW, Calgary, AB T2P 1H2

Dress Code: Business Casual

Open Time:  7:00 pm - 10:00 pm on 24th September 2019

AGIS VIII KEYNOTE SPEAKER: Dr. Rob Marriott, University of Calgary, AB

AGIS VIII Keynote Speaker will be Dr. Rob Marriott, University of Calgary, AB. His Presentation topic will be" Water Content of Acid Gas: From the Lab to the Field ". 

ABSTRACT: Due to composition and conditions, the vapour-liquid-equilibria within acid gas, sour gas or carbon dioxide injection processes can be relatively complicated to model with simple computational tools. This is particularly true when water is involved, because, in addition to the van der Waal forces responsible for simple cubic equations-of-state, hydrogen bonding plays an important role. Many-body interactions between water and sour gas molecules also lead to the formation of additional solid compounds (hydrates). Getting these models correct has significant consequences, as we are dealing with toxic and corrosive fluids. Furthermore precise models allow us to understand and design advanced handling techniques, such as the passive dehydration within multistage compression systems.

While simple models and simulation tools can be very successful, their calibration and verification with experimental data becomes more important. Several groups have sought to develop reference quality laboratory data for many years, where the measurement of the water holding capacity (water vapour pressure) under high-pressure and sour conditions has proven to be one of more difficult measurements to make with a high degree of confidence. With a specialized facility for working with hydrogen sulfide, it is no surprise that researchers at Alberta Sulphur Research Ltd. have been attempting to perform these measurements for some time. In this talk, the challenges and successes associated with high-pressure water content will be discussed with respect to acid gas fluids, sour gas fluids and hydrate systems. While we will focus on measurements, some modelling will be discussed with respect to reference quality correlations. 

Time: 8:15 am - 9:00 am on 25th September 2019


AGIS Roundtable discussion will be held on the last day of the symposium. All AGIS attendees will be welcome to join this program. In this program, we will invite five (six) experts who have rich experiences in AGI related disciplines as our panelists. They will answer all questions and share their knowledge. Everyone will have a chance to discuss their project achievements and problems.

Location: Second floor of Ramada Plaza Downtown Calgary

Address: 708 8 Ave SW, Calgary, AB T2P 1H2

Time:  1:30 pm - 5:00 pm on 27th September 2019

AGIS VIII Workshop II  - Russell Bentley, WSP, Houston, TX USA

Title : Injection Well Technology

Instructor Bio: Russell Bentley’s core area of expertise is drilling management for storage and disposal wells; his varied background also includes project consultation, business development, financial analysis, petroleum engineering and field management.

Russell is primarily  involved in reservoir and  aquifer storage and  underground waste disposal projects. He is a regional expert in acid gas injection, and served as project manager for recompletion of a 10,000-foot well for injecting hydrogen sulfide and carbon dioxide into a deep underground aquifer.

He also oversees consulting services to assess the condition of gas storage wells and establish plans and procedures to maintain their integrity. Earlier in his career, Russell served as a consultant on all aspects of greenhouse gas sequestration, including project management, drilling and well completions with gas plant retrofit designs, open-hole and cased-hole electric logging, reservoir engineering solutions, and mechanical integrity testing. Russell holds a bachelor’s degree in petroleum engineering from the University of Texas, and an MBA from Houston Baptist University. He is the co-author of several publications on acid gas injection.

Summary for AGIS VII

7th International Acid Gas Injection Symposium was held in the Sandman Hotel and Conference Center in downtown Calgary, Alberta, Canada. It was a very successful and a great conference.

AGISVII included one keynote speaker, 19 speakers, 20 presentations, 10 posters and two workshops. For detail program of AGIS VII, please click HERE.

AGIS is very grateful for the sponsorship we have received. It is safe to say that without our sponsors there would be no Symposium. AGIS VII have 9 sponsors and 75 attendees in total that came from different countries such as China, Japan, USA, France, Germany and Canada.

Congratulations to Miss Tu Hanmin, the winner of the inaugural Best Student Paper Award;

For the first time we had a site down Reception dinner at the Saltlik Restaurant.

AGIS VII keynote speaker was:

Mr. Jim Maddocks, PEng, PMP, CEO, Gas Liquids Engineering Ltd., Canada.

Topic: "Acid Gas Injection – A Very Dynamic Process"

Acid gas injection, while widely used throughout the energy industry, still has significant learning and development opportunities, particularly as flows and pressures increase, and operators begin to stretch the limits of conventional AGI design thinking.

This paper and presentation are intended to provide some background and thoughts on the nature of acid gas injection, the uncertainties, the possibilities, and the myriad of issues that can be present during a typical design cycle. With a significant number of rapidly changing inter-related process variables, the engineering/design team needs to consider acid gas injection as a very transient process. Adapting the design process and altering the way we approach, design, fabricate and finally operate acid gas injection systems requires some innovative critical thinking skills, some learning on the custom nature of the systems involved, and finally some realization that the AGI system will ultimately have to adapt to the environment.

Cutting Edge Technology For Carbon Capture, Utilization and Storage, 24th-27th September, 2017, Novotel Hotel and Conference Center, Clermont-Ferrand, France.

There is general agreement amongst the nations of the world that increasing amounts of carbon dioxide in the atmosphere are effecting the world’s climate. One option is to eliminate the use of fossil fuels but this is probably not going to happen in the short term. Thus carbon capture has emerged as a possible means for cleaner combustion of carbon-based fuels. Carbon capture is the removal of carbon dioxide from flue gas before it has been emitted to the atmosphere. Once the carbon has been captured it can either be injected in suitable subsurface formations (Carbon Storage) or converted to useful products (Utilization).

Understanding Natural Gas Hydrates

The "Understanding Natural Gas Hydrates" course will be soon  in Calgary. For 2017 course brochure, please click HERE.

Gas hydrates are ice-like solids that form at temperatures above the freezing point of water. They are frequently en-countered in the natural gas industry where water and hydrate forming molecules are in mixtures under pressure. However they are also found in other processes such as the olefins and other chemical process and in nature. The hydrates are notorious for plugging flow lines and damaging equipment. One must be careful when handling hydrate plugs or death could result!
       Time spent in the course is eligible for Profession Development Hours and a certificate will be issued after the course is finished, signed by the instructor and the organizer. More Details >>
