New paper on Eagle Ford play shows earthquakes induced by hydraulic fracturing

A new study published this week in Geophysical Research Letters indicates that much of the recent seismicity in the Eagle Ford shale gas play in Texas is induced by hydraulic fracturing. Fasola and her colleagues found a significant correlation between completion activity on wells and earthquakes close by. They further noted a large increase in seismicity that was coincident with the operations that was over 30 times the background seismicity rate for the area in 2018. The state seismic network, TexNet, provides earthquake locations to operators and the public during business day operations, but if operators need rapid and more timely access to data, ISTI provides a Rapid Notification Service from our cloud system that is operating 24×7. Get notified of an earthquake in your area of operation as it unfolds.

If more stations are necessary, ISTI provides rental equipment and crews to deploy stations at a moments notice. We also have professional seismologists to help with regulatory issues related to seismicity. Contact us today to see how we can apply our analytics and experience to your operation’s seismicity issues.

ISTI et. al “Radioxenon net count calculations revisited” article

ISTI is pleased to share the “Radioxenon net count calculations revisited” article from the Journal of Radioanalytical and Nuclear Chemistry, featuring Matthias Auer of ISTI as second author.

Abstract

Since 1998, there have been improvements in the capability to detect atmospheric radioxenon in the International Monitoring System operated by the Preparatory Commission of the Comprehensive Nuclear-Test-Ban Treaty Organization. The upgrades have resulted in next-generation versions of the radioxenon systems. This paper explores radioxenon data analysis
improvements beyond the original radioxenon beta–gamma analysis equations that were formulated in 2000 . . . read more here.

Register Now: Earthworm 5-day Course 2019

2019 Earthworm Course in New Paltz, NY, June 3 – 7

This 3 – 7 June, ISTI will host another of our popular Earthworm training courses in New Paltz, New York. This will be our traditional 5-day course. Our full ad may be found here.

We ask that interested students — and any colleagues who wish to join —

please register by 1 March via our contact form.

We’ll cover:

  • Installation
  • Configuration
  • Troubleshooting
  • Archiving and Playback of data
  • Data exchange
  • Visualization tools
  • Overview of various non-Earthworm post-processing options
  • Tuning for Earthquake Location and Magnitudes
  • Programming new modules, learning APIs

In addition, we will provide a tuning session for anyone that wants to bring their network’s Earthworm configuration to the course. We will show you how to playback your data and tune the earthquake location engine.

This course will be useful to anyone setting up, managing, tuning, or developing for an Earthworm system.  See full class details here (inc. location, transportation, etc.).

Again, if you plan to join the Spring ISTI EW 5-day class,

please register by 1 March via our contact form.

Thank you in advance for your confirmation of attendance.

ISTI Poster @ EGU 8 – 13 April

ISTI is pleased to announce that Comparison of Detection and Location Capabilities of Surface Microseismic Monitoring Algorithms, by ISTI authors, will be presented at the European Geosciences Union General Assembly, being held in Vienna, Austria on 8–13 April 2018.

Authors: Ilya Dricker, Paul Friberg, Sidney Hellman

Date: Thu, 12 Apr

Time: 17:30–19:00

Location: Hall X2, X2.382

Abstract

The challenge of the surface microseismic monitoring (MSM) is that small-scale seismic activity which occurs as a result of human activities or industrial processes is often hidden in surface noise on individual seismic records. MSM algorithms must detect and locate signals with average signal-to-noise ratio (SNR) significantly less than 1. To improve SNR MSM algorithms compute cost function over a large set of seismic records. Maximum of such function indicates presence, time, and location of the seismic signal. Other algorithms, such as Phase Robust Statistically Optimal and Diagonal Maximum Likelihood Adaptive algorithms offer accuracy improvements of location and detection in presence of correlated industrial noise. In this paper we use synthetic seismograms and seismic observation to compare accuracy of event locations using several algorithms of surface microseismic monitoring.
