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.

ISTI’s Rapid Notification Service in Oklahoma helps Operators meet new Oklahoma Hydraulic Fracturing Regulations that Require Seismic Monitoring

On February 27, 2018, the Oklahoma Corporation Commission (OCC) announced new seismic monitoring requirements for minimizing felt induced seismicity from hydraulic fracturing operations in the SCOOP/STACK play. The new requirements state that operators must have access to a seismic monitoring array.  They must take action at magnitue 2.0 (Richter scale) and pause for 6 hours at magnitude 2.5. This is a 0.5 reduction in magnitude levels from previous regulations.

News articles in Oil Price, Reuters, and Bloomberg News and in local Oklahoma media outlets KFOR, Tulsa World, and The Oklahoman are already reporting that operators are taking the new regulations seriously and are installing private networks like those installed and operated by ISTI and it’s partners (HMSC, Inc and GEObit). ISTI can help operators in this region with our real-time monitoring networks for the duration of their completions or for an entire field-wide view using our Rapid Notification Service (RNS) product. ISTI’s Oklahoma and Kansas subscription based RNS provides operators with the information to act before regulators react to any events that may be caused by their completion operations.  An example is a recent 2.1 magnitude earthquake; subscribers were notified within 2 minutes after it occurred (see event map with locating stations below). As a result of the rapid information, nearby operators could modify their well treatment plans for the next stages and attempt to mitigate further larger events.

The cost of being shut-down temporarily for any nuisance earthquakes can be quite high for operators. Rapid information provided by ISTI’s service can allow operators to take action before being required to pause or curtail operations. While the hazard of earthquakes induced by hydraulic fracturing is low, there is still the potential for it to trigger larger felt earthquakes as has been observed in Canada. Operators, on the other hand, can mitigate impact to their businesses by taking proper precautions.

ISTI & GFAST in Chilean News

Both Ben Baker of ISTI and GFAST were highlighted in El Mercurio newspaper on 6 February 2018 in the Chile aplicara sistema para agilizar alerta temprana de maremotos y terremotos article (loosely translated, Chile will apply system to streamline early warning of tsunamis and earthquakes).

Overview

An inherent difficulty in seismic-only earthquake early warning and tsunami forecasting is the rapid estimation of the earthquake magnitude and description of the rupture.  One novel approach is to augment the seismic-base system with geodetic information that can better capture the static-offset produced during large events.  In conjunction with the University of Washington, the Amazon Catalyst program, and the Centro Sismológico Nacional, ISTI is helping to make the Geodetic First Approximation of Size and Timing (G-FAST) production ready in the dynamic Chilean tectonic setting.   It is expected that the G-FAST enhanced Earthworm+Earlybird base system will be able to better characterize the frequent high-magnitude events on the Chilean subduction zone and ultimately improve rapid shaking and tsunami inundation estimates.

Announcing Article: “G‐FAST Earthquake Early Warning Potential for Great Earthquakes in Chile”

ISTI is pleased to announce a publication of G‐FAST Earthquake Early Warning Potential for Great Earthquakes in Chile, a collaboration between Ben Baker of ISTI and our colleagues in the field.  The article was published by SSA (the Seismological Society of America) and posted to GeoScience World on 7 February 2018.  ISTI wishes to recognize the authors:

Oklahoma hydraulic fracturing induced earthquakes in the news

A recent Bloomberg news article on increasing earthquakes in the Oklahoma SCOOP/STACK play is stating that regulators and the Oil and Gas industry are starting to turn their attention to monitoring hydraulic fracture induced earthquakes that are reportedly being felt in this region. While the predominant cause of induced earthquakes in Oklahoma have been tied to injection of produced waste water, hydraulic fracturing related earthquakes has received less attention until now. The Oklahoma Corporation Commission, which governs oil and gas wells in the state, was anticipating this back at the end of 2016 when they released guidelines that governed seismic concerns in this play. These regulations and the recent uptick in activity in this area suggest that monitoring for induced seismicity, like that done by ISTI, would be of great cost benefit to operators in the area so that they have operational information to head-off potential regulatory action.

Note that a similar news article was published in Bloomberg about hydraulic fracture induced earthquake concerns in Alberta Canada in the town of Fox Creek, where larger felt earthquakes have occurred in recent years.

Announcing Article: “Maturity of nearby faults influences seismic hazard from hydraulic fracturing”

ISTI is pleased to announce a publication of Maturity of nearby faults influences seismic hazard from hydraulic fracturing, a collaboration between ISTI and our colleagues in the field.  The article was published by the National Academy of Sciences on 5 February 2018.  ISTI wishes to recognize the authors:

Significance

Recent studies have focused on how wastewater disposal wells have caused dramatic increases in eastern US earthquakes. We focused instead on less common cases where hydraulic fracturing alone has caused earthquakes and found seismicity separated into two depth zones: a shallow zone on younger faults, with more small-magnitude earthquakes than expected, and a deeper zone on older faults, with larger magnitude earthquakes and seismicity continuing after fracturing stops. Hence, inducing deeper seismicity creates more hazard. Our observations are consistent with prior geologic, laboratory, and theoretical work indicating that age and maturity of faults causes the different seismicity patterns. We utilize data from well operators to demonstrate that both fluid pressure changes and rock stress transfer are needed to explain our observations.

Abstract

Understanding the causes of human-induced earthquakes is paramount to reducing societal risk. We investigated five cases of seismicity associated with hydraulic fracturing (HF) in Ohio since 2013 that, because of their isolation from other injection activities, provide an ideal setting for studying the relations between high-pressure injection and earthquakes. Our analysis revealed two distinct groups: continue reading.
