SPE Summer Social & Awards Ceremony

You’re invited to the highlight of our year! Join us at the legendary Brown Palace for the SPE Summer Social & Awards Ceremony—an unforgettable evening that blends the warm energy of our Summer Social with the sparkle of our Awards Banquet.

We’ll celebrate the brightest stars in Denver’s oil and gas community, honor our remarkable 25-year members for their lasting dedication, and share the stage with the newly elected 2026-2027 board. We’ll look back with pride on the successes of 2025-2026 and look forward with excitement to the bold goals ahead.

Come connect with colleagues and friends, raise a glass to excellence, and soak up the camaraderie that makes our section special. This is the evening where relationships are strengthened, achievements are celebrated, and we head into the year ahead with fresh energy and purpose. We can’t wait to welcome you—please join us!

Title: “From Heel to Toe: Engineering Uniform EGS Injection”

Abstract:

EGS circulates cooler water through hydraulically connected horizontal wells, creating a subsurface heat exchanger. Ideally, the injection is evenly distributed across the fracture network to promote uniform thermal drawdown; however, fracture variability and wellbore friction can concentrate flow in high-conductivity pathways or heel-biased stages, reducing sweep efficiency and accelerating thermal breakthrough. Modeling indicates conformance control providing uniform injection can increase 30-year power generation by 50%. This presentation summarizes surface qualification testing by GTO Technologies of a second-generation casing sleeve, pump-down actuation system, and high-temperature tractor designed to deliver uniform EGS injection independent of fracture conductivity. The system preserves full inner diameter from heel to toe and avoids telescoping ball seats while providing regulated flow through an outflow control device. The larger casing inner diameter also reduces parasitic pumping losses from wellbore friction and supports higher injection rates at lower pressures.

Speaker Bio:

Dr. Will Fleckenstein is a registered engineer and co-founder of GTO Technologies; a start-up funded with a $5 million seed round focused on commercializing EGS conformance-control technologies. He served as the PI for a $5.3 million DOE grant through the Utah FORGE project to develop the world’s hottest-temperature tractor and first-generation stimulation and conformance-control tools. Dr. Fleckenstein retired from the Colorado School of Mines on June 30, 2026, after 26 years as a non-tenure-track faculty member, including service as the Petroleum Engineering Department Head from 2012 to 2014. Dr. Fleckenstein has 40 years of industry experience, including a first job as a roughneck on rigs working in the Salton Sea geothermal field and has drilled, completed or worked over at least 200 wells in his career. Since 2009, he has also served as Board Chair of the Credit Union of Colorado, with170,000 members and $2.6 billion in assets.

Join SPE Denver for our monthly breakfast volunteer shift at the Denver Rescue Mission. This is an opportunity to give back to the Denver community, meet professionals from across the energy industry, and start your Tuesday morning in service to others.

Schedule: Third Tuesday of each month
Time: 6:45–8:30 a.m. Mountain Time
Address: 2222 Lawrence Street, Denver, CO 80205

RSVP: Please RSVP if you plan to attend. Questions may be directed to the volunteer coordinator at 303-257-6091.

Parking

1. Preferred: Use the private gated volunteer and staff parking lot on the right side of Lawrence Street. Look for the black metal fence and the large “Emergency Rally Point” sign. If the gate is closed and spaces are available, pull up to the gate, call 303-297-5071, and press 1 to have staff open it remotely.
2. Second option: A public pay lot is located across Lawrence Street. Some spaces marked “Denver Rescue Mission Staff Only” are available to staff and volunteers at no charge on a first-come, first-served basis. Pay the posted rate if a designated free space is unavailable. Parking costs cannot be reimbursed.
3. Third option: Metered street parking and other public pay lots are available in the neighborhood. Parking costs and tickets cannot be reimbursed.

Facility Entry and Check-In

Preferred entrance: Walk through the gated lot toward the back of the building, locate the white “Volunteer Entrance” sign, and ring the bell.

Alternative entrance: Enter through the main entrance on Lawrence Street. Front desk staff will escort you to the Volunteer Room.

Upon arrival, sign in using the kiosk tablet in the Volunteer Room. For a group, only one member needs to sign in for the group. Volunteers will then watch the required safety video before beginning the shift.

Volunteer Requirements

• Dress code: Wear modest clothing appropriate for meal service and kitchen work. Closed-toe shoes are required. Do not wear tank tops, midriff tops, short shorts, tight or low-cut clothing, controversial imprints, or loose and dangling jewelry. Volunteers who are not dressed appropriately may be asked to reschedule. Wearing a hat—and tying back long hair—may eliminate the need for a hairnet.
• Minimum age: Volunteers must be at least 14 years old. Anyone under 18 must be accompanied by an adult chaperone. Please do not bring guests under age 14.
• Incidents: Immediately report injuries, inappropriate behavior, or anything that makes you uncomfortable to a Denver Rescue Mission staff member.

Thank you for serving Denver community members who are experiencing homelessness.
