COMPLETIONS STUDY GROUP| Dual Fracturing Operations...

WHEN: Thursday, September 24, 2020 | 12:00 p.m. - 1:00 p.m.

WHERE: Zoom 


Title: "Dual Fracturing Operations - Logistics and Best Practices"


Dual frac is a novel idea to obtain significant pumping efficiency by pumping into two wells simultaneously with one frac crew. This method requires a significant amount of planning to align all the field services precisely and be prepared for any sub-surface pressure reactions that may require real-time job design changes. The stimulation job design, perforation schemes, on-site service providers, pumping equipment and monitoring were planned and optimized to ensure safe and effective stimulation treatment.

In this presentation, the step by step demonstration of the planned activities such as health and safety factors, the method of execution, reasons for Non-productive time and the operational gains made when comparing a zipper frac vs dual frac operation are explained.

SPE DISTINGUISHED LECTURER | Mitigating Production Degradation Due to Frac Hits

When: Wednesday, September 16, 2020 | 12:00 p.m. - 2:00 p.m.

Where: Zoom Meeting

Title: "Mitigating Production Degradation Due to Frac Hits in Unconventional Reservoirs"



In unconventional reservoirs, a "frac hit" is the infill-to-parent well communication during hydraulic fracturing. In most shale plays, production from the parent-infill well system drops below original forecasts due to production degradation after fracture hits from offset wells. This study reviews current methods to mitigate the production degradation and evaluates the effectiveness of these methods. Major challenges and opportunities are also presented.
The mitigation methods discussed in this lecture include (1) applying far-field diverter during fracturing in the infill wells, (2) reinjecting water into the parent wells, and (3) refracturing parent wells. Key design considerations for each method are presented in detail. A total of 565 fracture "hit events" at 41 impacted parent wells are statistically analyzed. Long-term well performance of several hundred impacted wells are also evaluated.
Based on the comprehensive analysis, the abovementioned three mitigation methods are field-proven and effective in protecting parent wells and improving infill well stimulation efficiency. With low operational costs, pumping far-field diverters results in a P50 EUR increment by 6%, with a 20% failure rate in the parent well protection. Water reinjection in the parent wells shows successful parent well protection, but the impact on the long-term well performance is negligible. Re-stimulation of properly selected parent wells with near-wellbore diverters indicates a P50 EUR increment by 40%. The selection of parent well protection methods needs to be fit-for-purpose and is fundamentally dictated by well conditions, operational experience, and economic models applicable to the area.
Take-away: "Frac hit" mitigation methods need to be fit-for-purpose and are fundamentally dictated by well conditions, operational experience, and specific economic models.

DENVER SPE | Webinar: Comparative Summary of Conventional O&G Injectors...

When: Wednesday June 17, 2020 | 12:00 p.m to 1:00 p.m

Where: Zoom Link 

Event Registration Link

Title: "Comparative Summary of Conventional O&G Injectors, CO2 EOR and CO2  Storage Injectors"

Speaker: Talib Syed, P.E.


Increased concerns globally from greenhouse gas emissions (principally from carbon dioxide – CO2 and methane – CH4) and related climate change and global warming impacts have led to an increase in the number of carbon capture and underground storage (CCUS) projects around the world. The U.S. oil and gas industry has led the world in the utilization of CO2 for Enhanced Oil Recovery projects since the 1950s (with 70% of the world’s CO2 EOR floods located in the Permian Basin of West Texas). It has the technology, experience and know-how to enable safe long-term storage of CO2 primarily in deep saline formations, or in depleted oil and gas reservoirs.

This Webinar presents a summary of the key comparative factors between conventional oil and gas injectors, CO2 EOR and CO2 storage injectors that have to be considered during the life cycle of a well. These factors include: (1) High Injection/Operating/Reservoir Pressure Management, (2) CO2 Corrosion, (3) Well Design & Construction, (4) Well Integrity, (5) Material Selection, and (6) Plugging and Abandonment.


Talib Syed, P.E. holds a B-Tech (Chemical Engineering – Univ. of Madras, India) and an M.S. in Petroleum Engineering (Univ. of Oklahoma) and is a Registered Petroleum Engineer in CO and WY. Talib started his oilfield career with ARAMCO – Saudi Arabia and has U.S. and international experience – both onshore and offshore. Talib has been selected as a SPE Distinguished Lecturer on Life Cycle Well Integrity for the 2020-2021 Program Period and currently serves as SPE Denver Section Chair – HSES/Facilities and SPE Member-at-Large CCUS Technical Section. He is a member of American Association of Drilling Engineers (AADE – Denver Chapter), Interstate Oil and Gas Compact Commission (IOGCC) and Ground Water Protection Council (GWPC).

SPE YP | Lunch and Learn: Illuminating Wells With Intervaention-Based Fiber Optics

When: Wednesday, March 11, 2020 | 11:30 a.m.

Where: Liberty Oilfield Services | 1950 17th St, Suite 2400, Denver, CO


Speaker: Matthew Lawrence, Senior Technical Advisor & Ahmed Attia, Reservoir Manager, Ziebel


Better data informs better decision making. Multiple factors impact well and completion performance that are not discernable from surface production data alone. How can operators understand which factors are impacting their completion optimization efforts? Distributed fiber optic sensing (DAS and DTS) is playing a pivotal role in advancing operator understanding of stimulation and production performance. However, permanent fiber installations are cost-prohibitive, restricting utilization or limiting the scope of data collection to a single well in a single section of a play.

Intervention based fiber optics are a cost-effective alternative allowing a broader scope of diagnostic efforts. This presentation will review applications of deployed fiber optics for evaluating stimulation and production uniformity, completion efficiency, and well spacing. These real-world case studies demonstrate how data gathered by distributed sensing is equipping operators to produce better wells sooner.



Matthew Lawrence is a Senior Technical Advisor at Ziebel. He’s worked in the upstream oil and gas for 19 years, introducing new technologies to aid operators in diagnosing completion and reservoir behavior. Over the past five years, he’s helped create and grow the market for intervention-based distributed fiber optic sensing (DAS+DTS).


Ahmed Attia is the North American Reservoir Manager who leads the reservoir group at Ziebel US. With over 10 years of experience in the energy sector, Ahmed has focused on developing an in-depth understanding for unconventional wellbore behaviors and completion designs. Currently focused on DAS and DTS Ahmed has played a key role in the development and implementation of Ziebel’s leading wellbore and completion analysis .

Lunch will be provided.

GENERAL MEETING | Enhanced Oil Recovery (EOR) for Unconventional Reservoirs: The Next Big Thing?

When: Wednesday February 19, 2020 | 11:30 a.m to 1:30 p.m

Where: Denver Athletic Club | 1325 Glenarm Pl., Denver, CO

Speaker: Dr. Todd Hoffman, Associate Professor, Montana Tech 


Unconventional reservoirs have had tremendous success over the last decade due to technical advances including long horizontal wells and multi-stage hydraulic fracturing; however, their potential may be even higher.  There are trillions of barrels of oil in these resources, and while wells start out at high rates, they decline quickly and primary recovery factors are low, often in the single digits. This clearly indicates a need for some form of enhanced oil recovery (EOR) for these types of reservoirs.In this presentation, the efforts to implement EOR in unconventional reservoirs will be examined in full detail. A number of different injection fluids have been proposed including miscible gas, water and surfactants. Early work focused on modeling and lab studies, and this provided a base of knowledge that was leveraged to carry out pilot field studies. Pilots have been implemented in at least four basins, and the Bakken and Eagle Ford have both had multiple field trials. Huff-n-puff natural gas injection has been shown to be very successful in the Eagle Ford, and today, large-scale field development is occurring there.

Because most of the field trials have been completed in North America, the examples presented are mainly from there; however, as these techniques are reproduced in other basins, the worldwide potential is enormous, and that potential also is discussed in the presentation.

While much has been achieved over the last decade in unconventional reservoirs, implementing EOR in these types of reservoirs will likely bring about even greater success.


Todd Hoffman is an Associate Professor in the Petroleum Engineering Department at Montana Tech. He teaches classes on Reservoir Simulation, Enhanced Oil Recovery, and Unconventional Reservoirs. Prior to that, he was a reservoir engineering consultant to the oil and gas industry. Todd has worked on reservoir models for more than 30 fields on six continents, and has published over 50 technical papers. His research involves improved recovery for conventional and unconventional reservoirs, fractured reservoir modeling and history matching. Todd received his B.S. in petroleum engineering from Montana Tech and his M.S. and Ph.D. in petroleum engineering from Stanford University.

Where are Data and Technology Taking Us?

Recent advances in unconventional hydraulic fracturing have been characterized by a continuous series of operational leaps forward. The technology advances that have mattered most for dramatic recent industry efficiency gains have included the application of critical process and product improvements, real-time data processing, process simplification, system automation and just-in-time supply chain streamlining. As we enter 2020, we find ourselves asking where the next big advances will come from. What will the next key technological advances be and where and how will they be applied? We believe there is a large role for big data analysis and its use with Machine Learning (ML) and Artificial Intelligence (AI) among others. This session brings a group of experts from varied industries together to discuss what the industry is already doing with these technologies, and where the hydraulic fracturing and unconventionals industry may be heading.
