GENERAL MEETING | Frac Trends in Liquid-Rich Basin

When: Wednesday December 18, 2019 | 11:30 a.m to 1:30 p.m

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

Speaker: Dr. Leen Weijers, Vice President of Engineering, Liberty Oilfield Services LLC


This presentation reviews how the industry achieved a step-change in reducing service delivery cost through innovation and efficiency, allowing sustained economic development of unconventional resources at decreasing breakeven production costs.  Technological changes, as assisted by a better understanding through frac diagnostics, integrated modeling and statistical analysis have enabled the large cost reduction to commercially produce a barrel of oil.  As a result, shale frac designs have focused on higher intensity completions with tighter stage and cluster spacing, improved diversion through extreme limited entry perforation design and simultaneous and zipper frac’ing, increasing proppant mass per well, utilizing next-generation frac fluids to increase produced water recycling and using cheaper lower-quality proppant.  At the same time, the environmental footprint of oil & gas production has been shrinking and will continue to do so as operational changes continue to make our industry a better neighbor, for example through faster well construction utilizing fewer pad locations, development of quiet fleets, greener frac chemistry, frac focus disclosure, etc.  Together, oil and gas operators and their service providers have used technology & innovation to improve efficiencies and increase the overall daily pump time per frac crew.  However, there is plenty of room for further improvements in technology and efficiency.

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.

RESERVOIR STUDY GROUP | Application of Reservoir Simulation to Unconventional Reservoirs

When: Thursday, November 21, 2019 | 11:30 a.m. to 1:00 p.m.

Where: Halliburton Office | 1127 17th St, Suite 1900


Numerical reservoir simulation, when properly employed, is the most robust tool available for supporting decisions making in unconventional reservoirs.  It can be used to estimate number of wells per DSU, horizontal and vertical well placement, hydraulic fracturing optimization, sequence of fracture treatments for pad completions, parent child well interaction, and placement of infill wells in the areas of depletion, re-fracturing and EOR design and implementation.

 It is no longer adequate to simulate and forecast single well simulations to estimate a well’s EUR. The vertical and lateral complexities of the unconventional resource, the timing of neighboring well fracture treatments, and nearby well production all impact the performance of individual wells and the pad. These phenomena can only be properly captured in multi-well simulation models that account for the fracture treatment timing, along with well pressure and production rate responses.

 Dual-porosity reservoir simulation integrated with geomechanical features which capture both SRV generation during hydraulic fracturing and the SRV geometry changes during production is the most applicable modeling technique to address the complexities associated with unconventional resources.

 In this seminar the application of physics based reservoir modeling and simulation for unconventional reservoirs will be discussed.  The predictive capabilities of such models will be demonstrated with field examples.

GENERAL MEETING | Thriving in a Lower for Longer Environment

When: Wednesday November 20, 2019 | 11:30 a.m to 1:30 p.m

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

Speaker: Mary Van Domelen, Well Data Labs


When the price of oil plunged in 2014, industry analysts predicted that shale plays would be shutdown as they would no longer be economical. In reality, the North America shale industry did not just survive, it thrived. How?

The most successful companies responded by exercising capital discipline and effectively managing their resources. As a result, breakeven prices for the key unconventional plays were decreased by 40-60%. Reduction of service pricing alone cannot account for the improvement in profitability relative to oil price. What other factors contributed? 

This presentation captures the key lessons learned. The organizational, operational, and technological advancements which allowed the shale industry to continue to thrive in a “lower for longer” price environment are illustrated through case histories. Geologists worked to identify each play’s core, while companies evolved from delineation to full field development. The synergistic effect of combining new technology with operational efficiency is illustrated by the ability to drill longer laterals with significant decreases in drill days. Completion optimization, fueled by the use of big data analytics, resulted in drastic increases in EUR allowing expansion of the core in many plays. Improvements in artificial lift technologies accelerated early time production, significantly increasing the net present value of capital employed. Throughout all these processes, cooperative relationships between the service sector and E&P companies was imperative to the continued success of the industry.

Can the lessons learned by the shale industry be applied in the global setting?  Absolutely.

GENERAL MEETING | Production Optimization...

When: Wednesday October 16, 2019 | 11:30 a.m to 1:30 p.m

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

Title: "Production Optimization of Conventional and Unconventional Wells with ESP Real Time Data"

Speaker: Lawrence Camilleri, Schlumberger


Optimizing production has always been important, but there is naturally a greater focus on high rate wells, such as those produced with ESPs (Electrical Submersible Pumps). A key driver is arresting decline while minimizing infill drilling, which is often achieved by identifying wells with skin to identify stimulation candidates and increasing drawdown on wells with good pressure support. With unconventionals, accelerating production while minimizing power consumption become dominant goals. This presentation explains how real-time gauge data enables high-frequency, high-resolution downhole flow rate measurements on ESP wells. Thereby providing both rate and pressure, which are essential to enabling inflow characterization and thereby identifying optimization opportunities without the need for traditional buildups, which cause production deferment.

Fortunately, technology advances have improved real time data quality in terms of both sampling frequency and metrology.  There has also been a reduction in the cost of measurement, transmission and storage, which signals the true dawn of the digital age. The presentation therefore also reviews how real time data enables increases in well uptime and ESP run life as well as minimizing power consumption.  Using material from recent SPE papers, both theoretical methodology and real case studies are presented to illustrate the value of real time data for both conventional vertical wells and unconventional multifracked horizontal wells.  While the case studies are based on ESP applications, the lessons learnt on how to extract value from real-time data can be applied to other artificial lift techniques, especially since inflow characterization is generic.


Lawrence has over 33 years of experience in production operations of which 27 years have been focused on artificial lift in a variety of roles ranging from field and application engineer to his current role as Global Domain Head, which is Schlumberger’s most senior technical position in the Artificial Lift Division.  He has published over 16 SPE conference papers and 3 patents covering all aspects of ESP operation such as inflow characterization and advanced completions.  This body of work is particularly noteworthy as it combines theoretical explanations and field case studies using real time data.
