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

Abstract: 

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 | 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: B. Todd Hoffman, Montana Tech 

Abstract: 

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.
