Modeling and Simulation Forum #5

Utah FORGE Modeling & Simulation Forum #5


"Back Analysis of Injection Tests in Zone 2 on Well 58-32"

Presented by: Branko Damjanac (Itasca), Pengju Xing (University of Utah), and John McLennan (University of Utah)

October 28 at 11 am MDT

During Cycles 4 in Zone 2 on Well 58-32 water was injected at 5 bpm for 5 minutes. After approximately 20 hours of shut-in, Cycle 5 injection test was conducted at the same perforation cluster, again at 5 bpm for 5 minutes. The pressure histories after breakout exhibit generally increasing trends during injection. Interestingly, the pressures during Cycle 5 are greater than during Cycle 4.  The entire test, including Cycles 4 and 5, was back-analyzed using a fully coupled hydro-mechanical model with explicit representations of DFN of different levels of detail. The objective of the back analysis was to calibrate the model with respect to unknown and uncertain parameters and match the pressure histories, and in particular the increasing trends and greater pressures during Cycle 5.

This is the fifth forum of the series and is intended to have an open format to present modeling and simulation, both completed and planned, as well as activities being conducted by the Utah FORGE Team.

The forum requires registration.

"Coupled Simulations of Well and Reservoir Thermal Hydraulics"

Presented by: Robert Podgorney  and David Andrs (INL), Aleta Finnila (Golder),

Pranay Asai (University of Utah)

 

August 19 at 11 am MDT

The forum features a discussion of the development of coupled well hydraulics and reservoir hydraulics simulations. These simulations are being prepared in preparation for conducting long-term operational simulations of the FORGE reservoir, where multistage stimulation and limited entry are anticipated in the injection well. The presentation will provide a summary of the well flow simulator, numerical coupling between the well and the reservoir, and provide a few preliminary examples.

This is the fourth forum of the series and is intended to have an open format to present modeling and simulation, both completed and planned, as well as activities being conducted by the Utah FORGE Team. This webinar has been recorded and is now available for viewing.

Modeling and Simulation Forum #3

Utah FORGE Modeling & Simulation Forum #3

"Injection Testing and Stress Measurements" presented by Pengju Xing and John McLennan (University of Utah)

June 17 at 11 am MDT

"The forum will address injection-based stress assessments were carried out in the openhole toe and in a cased/perforated section in a pilot vertical well in 2017 and in 2019. The basic measurement program is described, and the familiar complexities of interpretation discussed. Additional discussion will briefly describe flowback and temperature as diagnostics for in situ stresses.

Future modeling activities will include history matching legacy injection data using Schlumberger’s Kinetix and Itasca’s XSite. With calibration from this history match, predictive simulations will be carried out to help to comprehend fracture morphology during future injections at the toe of the first FORGE extended reach well.

This is the third forum of the series and is intended to have an open format to present modeling and simulation, both completed and planned, as well as activities being conducted by the Utah FORGE Team. This webinar will be recorded and will be available for viewing later.

Please note registration is required for the forum and seating is limited.

Modeling and Simulation Forum #1 RECORDING

The inaugural Modeling and Simulation Forum was held on April 15, 2020 and if you weren't able to participate you can check out the video recording of the webinar below.

Topics that were covered included an overview of the Utah FORGE project, a description of the numerical methods and codes that have used, a summary of modelling results dealing with discrete fracture network, the distribution of stress, and the planning of well trajectories.

This will be a recurring event to keep the EGS community updated on our activities and, most importantly, to gain the community's feedback.
