Temperature logs, pressure logs, directional survey, well history, well bore schematic, and other reports for well 48-11TCH at West Flank FORGE

Paper authored by Stumpf et al. for the 2018 Geothermal Resources Council Annual Meeting held in Reno, NV USA. Included with the paper is the Microsoft PowerPoint presentation made at the GRC meeting and data tables associated with some of the figures.

This is a project description video by Dr. William W. Fleckenstein related to their "Development of Multi-Stage Fracturing System and Wellbore Tractor to Enable Zonal Isolation During Stimulation and EGS Operations in Horizontal Wellbores" R&D project at Utah FORGE which is linked...

A summary of wellbore stresses determined using faulting theory, breakouts, drilling-induced cracks detected in image logs.

This project assessed the technical viability of a process called GeoCAES. The process stores electrical energy by injecting natural gas into shale gas formations using a compressor, storing it, and producing it through an expander to generate electricity. This data submission inc...

Polymer-cement experiments were conducted in order to assess the chemical and thermal properties of various polymer-cement composites. This file set includes the following polymer-cement analyses: Polymer-Cement Composite Synthesis Polymer-Cement Interactions by Atomistic Simulat...

Metadata for DTS and DAS datasets for both borehole 56-1 and trenched cables.

Operational performance requirements are needed to support development of specifications for downhole motor power sections to be used for drilling hard rock during geothermal wellbore construction. Theoretical torque specifications are derived based upon a widely-accepted rock-re...

Well completions are an integral part of providing safe, reliable and continuous access to underground resources such as oil, gas and geothermal resources. Completions are typically considered to be the final step of drilling engineering which includes processes such as setting c...

Paper title "Experimental study on rheological and settling properties of shape memory polymer for fracture sealing in geothermal formations". The paper was published in the Journal of Petroleum Science and Engineering 208 (2022) 109535.

SMP Modeling_ PSD and effectiveness in fracture sealing After building the CFD model, the coupled CFD-DEM simulations were used to generate about 100 cases that have different size distributions. We have determined that the best fracture sealing results come from the bimodal distr...

The paper was presented at the 46th Workshop on Geothermal Reservoir Engineering, Stanford University, Stanford, California, February 15-17, 2021. In this study, the effectiveness of different additives was evaluated in maintaining drilling fluid rheology at HPHT(high pressure and...

Directional Cooling-Induced Fracturing (DCIF) experiments were conducted on a short, cylindrical sample of Westerly granite (diameter = 4 inches, height ~ 2 inches). Liquid nitrogen was poured in a copper cup attached to the top of the sample, and the resulting acoustic emissions ...

Rheology Screening for Mud Additives The rheology screening experiments aimed to evaluate the performance of different additives to be used as viscosifier for the base fluid. Different fluid formulations were prepared in the lab by adding the additives individually to tap water in...

The steel pipe experiment conducted in the lab was using 6 meter low-carbon steel pipe. We tested it with both dry and in-water condition. In the dry experimental setup, a coaxial cable acting as a return path in the air.

Paper title "Evaluating sealability of blended smart polymer and fiber additive for geothermal drilling with the effect of fracture opening size". The paper was published in the Journal of Petroleum Science and Engineering 206 (2021) 108998.

Includes specification sheet, wellbore geometry, and drilling fluids at section target depth associated with the design of Injection Well #1 (CCS1) for the Illinois Basin Decatur Project (IBDP).

Natural fracture data from wells 33-7, 33A-7,52A-7, 52B-7 and 83-11 at West Flank. Fracture orientations were determined from image logs of these wells (see accompanying submissions). Data files contain depth, apparent (in wellbore reference frame) and true (in geographic referenc...

The coaxial-cable experiment conducted in the lab was with 80 m coaxial cable( RG-85). This experiment compares the TDR response between damaged and undamaged cable. For the damaged cable, the damaged section is in the middle (40 m). The amplitude of the data is mV with time (us).
