Janz Rondon is a Senior Consulting Engineer at ResFrac, providing value to the energy industry by optimizing the development of fracturing and reservoir projects.

He provides a unique combination of engineering and management experience from a variety of roles in operations, sales, training, technical, and business development. Janz worked at Schlumberger for over 17 years as a fracturing and engineering manager, leading and completing projects and teams across multiple basins in North America. His previous role was the lead instructor and learning manager for multiple product lines at the global learning center. He is the recipient of the 2018 Completion Optimization and Technology Award – Rocky Mountain North America Region, Society Petroleum Engineers.

Janz attended the Universidad de los Andes in Bogota, Colombia where he completed his bachelor studies in civil engineering and masters in geotechnics. He resides in Denver, Colorado with his wife and three children. He is passionate about the cycling world, particularly building bicycles and optimizing athletic performances in the sport. Janz was originally transferred to the US from Colombia, without any knowledge of English. He picked it up while working for Schlumberger in the Wyoming and North Dakota fields.

Advanced ‘proppant transport in the well’ capabilities are now implemented in ResFrac!

Proppant transport in the well is an intriguing topic that has attracted a lot of interest in recent years [1-8]. Proppant transport processes determine the uniformity of proppant placement, which has a direct impact on productivity. Cipolla et al. estimate that the difference between poor and excellent proppant uniformity is about $2.5M in net present value per well.

Digesting the Bonkers, Incredible, Off-the-Charts, Spectacular Results from the Fervo and FORGE Enhanced Geothermal Projects

I’m out of superlatives – I used them all up in the title. But seriously – Enhanced Geothermal System (EGS) projects have had a really, really good summer. In this article, I summarize the results that have been recently presented by Fervo and FORGE. At their annual Tech Day and in a white paper posted this week (Norbeck et al., 2024), Fervo Energy provided their first update on Project Cape, a Utah project where they are developing 400 MWe of new production over the next two years. So far, fourteen wells have been drilled, and three of them have been stimulated.

What ‘company culture’ means to us

We recently held our annual company retreat. This is an important event because we are a fully remote company, and it gives us the chance to get together in-person and spend quality time. This year, we did the retreat in Houston, following URTeC and our annual symposium. We visited Space Center Houston, went to an Astros game, and ate BBQ and Tex-Mex. As a Houston native, I picked some of my favorite things to do in town! We also held a meeting on ‘company culture.’ I asked the group – how do you perceive our company culture? What do we do well, and what could we do better? Here are the highlights.
