Abstract

Drilling results from the microhole project at the Sandia High Operating Temperature test facility. The project is seeking to help reduce the cost of exploration and monitoring of geothermal wells and formations by drilling smaller holes. The tests were part of a control algorithm development to optimize the weight-on-bit (WOB) used during drilling with a percussive hammer.

Microhole Tubing Bending Report

Dataset Oglesby, Ken

A downhole tubing bending study was made and is reported herein. IT contains a report and 2 excel spreadsheets to calculate tubing bending and to estimate contact points of the tubing to the drilled hole wall (creating a new support point).
Microhole VSP - CO2 EOR - Wickett, Texas

Dataset Daley, Thomas M.

This data archive is three vertical seismic profile (VSP) data sets recorded in 2007 and 2008 using microhole technology to monitor a CO2 EOR flood in a Wickett, TX oil field (known as North Ward/Estes field). Five microhole wells with permanent vertical component geophone sensors were used for monitoring.
Microhole drilling technology utilizing a golden section search algorithm

Dataset Su, Jiann ; Mazumdar, Anirban ; Buerger, Stephen ; ...

A fundamental issue in microhole drilling is that delivering high weight-on-bit (WOB), high torque rotational horsepower to a conventional drill bit does not scale down to the hole sizes necessary to realize the envisioned cost savings An optimization algorithm called a golden section search (GSS) was used to systematically identify the preferred WOB for a given set of conditions. This research focused on implementing and evaluating two low WOB drilling technologies for microhole drilling: - Laser-assisted mechanical drill, which was tested in the laboratory - Lightly modified commercial off-the-shelf (COTS) percussive hammer, which was tested in a limited field test.more »« less

Utah FORGE Project 2439: Well 16B(78)-32 Field-Test Data from Mini-Frac Tests

Dataset Kelley, Mark ; Skopec, Stuart ; Mawalkar, Sanjay ; ...

This submittal includes the field-test data collected during stress tests conducted in the Utah FORGE 16B(78)-32 wellbore to measure/characterize the stresses in the geothermal reservoir. The type of stress test performed is referred to as a mini-frac test or a micro-frac test. The test is a hydraulic fracture test that involves injecting a small volume of water into a short interval of the reservoir that is isolated by a straddle packer to create a fracture. The test provides information about the minimum and maximum horizontal stress at the test depths. A total of seven mini-frac tests were performed within themore »« less
