The experimental data obtained in this project is the thermal stability data of various foams measured using the setup established at Temple University during this study. The setup is installed with a portable digital camera which can take images and videos of foam evolution at a ...

In this paper, the combustion of nitrous oxide with a simple hydrocarbon, ethylene, at high initial pressures is investigated. A series of experiments were conducted using a stoichiometric C2H4-N2O mixture in a round, smooth-walled tube with initial pressures of 125 to 337 psi. ...

Pushing the boundaries with geothermal tool development can often necessitate exceeding manufacturer specifications for temperature and pressure of individual circuit components. Detailed here are the efforts surrounding geothermal temperature characterization of commercially avai...

Pressure data recorded using PANEX pressure gauges at the bottom of wells CFU31-F2 and CFU31-F3.

Project: High Temperature Chemical Sensing Tool for Distributed Mapping of Fracture Flow in EGS. Preliminary pH and reference electrode test results.

Pressure data acquired in well F2 and F3 during the CO2 geothermal thermosiphoning test, Cranfield MS.

Objectives Options associated with geothermal drilling operations are generally limited by factors such as formation temperature and rock strength. The objective of the research is to expand the "tool box" available to the geothermal driller by furthering the development of a hig...

Project status report as of end of 2011. Key milestones and accomplishments in the year 2011 include: Proof of feasibility of analog and digital components with their lifetime tested for more than 500 hours at 300 degrees C, Demonstration of ceramic-based packaging capable of su...

The results are from three kinds of tests: HPHT LCM Rheology, LCM PSD Analysis, and HPHT LCM Fluid Loss Tests. HPHT LCM Rheology Rheology tests were performed up to 200C, and we found that some of the most popular LCMs, such as sawdust, cottonseed hulls, or walnuts, are prone to...

Due the high temperature and pressure conditions found in geothermal wells, tracer studies designed to elucidate properties of geothermal reservoirs are traditionally conducted by pulling liquid samples from the wellhead. These samples are then sent off for analysis in a fixed lab...

There is an ongoing effort at Oak Ridge National Laboratory to develop a unique experimental capability for investigating flow through porous and fractured media using neutron imaging techniques. This capability is expected to support numerous areas of investigation associated wit...

For enhanced or Engineered Geothermal Systems (EGS) geothermal brine is pumped to the surface via the production wells, the heat extracted to turn a turbine to generate electricity, and the spent brine re-injected via injection wells back underground. If designed properly, the sub...

Understanding the relationship between stress state, strain state and fracture initiation and propagation is critical to the improvement of fracture simulation capability if it is to be used as a tool for guiding hydraulic fracturing operations. The development of fracture predict...

The aim of this study is to understand how commercially available elastomers perform under geothermal well-like conditions and make recommendations to the community based on these results. This poster highlights the mechanical performance of several elastomers (including EPDM, Vit...
