GENERAL MEETING | Leading the COGCC Lessons Learned and Industry Implications

When: Wednesday November 18, 2020 | 11:50 a.m. to 1:00 p.m.

Where: Zoom meeting


Speaker: John Benton, Chief Development Officer, Hydroacoustics, Inc.


The presentation uses changes to laws, policies, regulations, and Colorado Oil and Gas Commission makeup from 2011-2020, along with additional data, as the basis for the conclusion that the hostile oil and gas environment in Colorado could happen anywhere in North America much to the detriment of the industry.

The presentation lists the proactive rulemakings undertaken by the Commission to adapt to changing public and state government perceptions of the industry during that time frame. It summarizes restrictive legislative changes that occurred as a result of the public viewing the Commission’s rulemakings as not moving fast enough to adapt to increasing residential development in one of the hottest shale plays in North America.

The presentation covers the signals industry missed that resulted in restrictive legislation, the consequences of increasingly strict rules on oil and gas investment in Colorado, and discusses why the same thing could happen in other states. It briefly discusses what the industry can do to reduce the possibility of having what happened in Colorado happen elsewhere.

Finally, the presentation discusses some of the recent Colorado rulemakings and their implications to oil and gas development in Colorado.

COMPLETIONS STUDY GROUP| Biocides in Hydraulic Fracturing and Why You Need One to Protect Your Well

When: Thursday November 12, 2020 | 11:45 a.m. to 1:00 p.m.

Where: Zoom

Speaker: Matheus Paschoalino, Sr. TS&D Specialist for Microbial Control, Dupont



Microbial Control is an important topic in Oil & Gas operations but it is often neglected due to the complexity or specificity of this subject. Many of the key problems seen during oilfield operations may have a crucial contribution from microbes metabolisms initiating or enhancing corrosion, scaling, souring, clogging and impacting directly on the productivity and operational costs. The dynamics, mixtures and reuse of the fluids in a Hydraulic Fracturing operation enable perfect conditions for the proliferation of a diverse population of microorganisms, which may behave different depending on each environment characteristics, demanding different biocide technologies according to each situation. The water composition and the complexity of the fracking additives plays a critical role on the biocide selection since unintended interactions may disactivate those actives instantaneously.  This presentation will discuss some of the main paradigms of microbial control in Hydraulic Fracturing related to the need of a biocide on extreme environments, the key differences, limitations and interactions of the main biocides used on this industry.  Furthermore, the presentation will highlight the importance of adequate monitoring and correct data interpretation to avoid the selection of an ineffectual biocide, resulting in high and reoccurring operational costs


Matheus Paschoalino is a Sr. TS&D Specialist for DuPont Microbial Control. He received his doctoral degree from the University of Campinas (Brazil), including a stage at the University Complutense of Madrid (Spain). He has fifteen years of experience in Research, Development, and Technical Support on industrial water treatment and microbial control technologies focusing on delivering asset integrity solutions for energy and mining markets.

When: Tuesday, October 27, 2020 | 12:00 p.m. - 1:00 p.m.

Where: Zoom

Title: “Honing the Zone” for the Ideal Well: Using Chemical Tracers to Understand and Gain Efficiencies in Different Plays


Speaker: Patrick Hayes, Business Development Manager North America - Tracerco


Using case studies, this presentation highlights the undeniable influences of different formations, their geology, potential landing zones, and completion designs on the overall production of wells. By combining quantified stage production of water, oil, and gas phases into a 4D model and evaluating stage performance overtime, new alternative development strategies have been created for different formations to achieve increased efficiency. Case studies will include parent and child well relationships for multiwell pads, how operators have used tracers to evaluate landing targets, and how different completions design effect production and cleanup efficiency.

PRODUCTION STUDY GROUP | A Reservoir Engineer's Guide...

When: Thursday October 22, 2020 | 11:45 a.m. to 1:00 p.m.

Where: Zoom

Title: "A Reservoir Engineer’s Guide to Fit-for-Purpose Completions- Minimum Spend for Maximum Performance"

Speaker: David Anderson (B.Sc., P.Eng.) ,CEO of SAGA Wisdom.


Technology has delayed the once considered inevitable “peak oil” and its subsequent decline, permitting the commercialization of oil and gas resources that were previously thought to be unmovable. Along with this, a “bigger is better” trend has emerged, which has seen an enormous influx of capital into completion and fracture stimulation operations. This trend has resulted in unprecedented production growth, year over year – but at what cost? With the collapse of the global oil market, we now face the imminent challenge of “peak demand” and smart oil and gas companies are streamlining their operations, looking for ways to lower production costs, while favoring positive cashflow over production growth. The concept of fit-for-purpose completions fits perfectly within this new paradigm. Executing successful fit-for-purpose completions requires understanding the unique connection between the completion and the reservoir, and squeezing the maximum economic benefit from every play. Overall, this is something the industry has not done well, in the past. This presentation focuses on basics such as completion compartmentalization, well placement, frac surface area, complexity and conductivity – and how to ensure these are optimized for specific reservoir types while avoiding over (or under) capitalization.

GENERAL MEETING | Sustained Casing Pressure...

When: Wednesday October 21, 2020 | 12:00 p.m. - 1:00 p.m.

Where: Zoom

Title: Sustained Casing Pressure: Where are we and what is working across the United States?


Speaker: Geoff Landry, Schlumberger’s North American Cementing Technical Manager


Sustained casing pressure (SCP) has been an ongoing issue for both new and old wells in the DJ Basin and around the United States.  The best, and often most cost-effective long-term solution to SCP is to prevent it in the first place, so an effective primary cement design is critical.  If encountered after the primary cement placement or post fracture treatment, SCP is a complex problem requiring a comprehensive, often well-specific solution involving advanced techniques for identifying the source of gas influx and the implementation of a tailored remediation design.  This iterative process has evolved over the past several years, and many lessons have been learned that have led to the successful prevention and remediation of SCP.  Please join us as Schlumberger’s Domain Champion Geoff Landry discusses “what’s working where and why,” from a technical perspective from around America.

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.
