Abstract: Injection-Induced Seismicity: End of the Beginning?

For the last several years, there have been numerous technical workshops on injection-induced seismicity which, looking back, serve as snapshots documenting the rapid evolution in our understanding of this important topic. With time, the tone of these workshops has changed in step with advancement by industry, regulators and academics managing this critical issue. Early discussions focused on education and awareness of the causes and cases of induced seismicity. This was followed by reactive implementation of regulated traffic light systems, and now development of more proactive operational strategies to mitigate induced seismicity.

Abstract: Ranking Operation Scenarios for Effective Mitigation of Hydraulic Fracture-Induced Seismic

A magnitude-based, traffic light protocol is the most common mitigation approach to injection-induced seismicity, adopted by both regulators and operators throughout North America. Despite challenges associated with a protocol based on an estimate of seismic source strength, magnitude-based protocols still prevail over alternatives such as using measured ground motions.

Abstract: Economics of Induced Seismicity: Trying to identify faults in the horizontal well planning

“Induced seismicity” refers to a seismic event that is caused by pore pressure and stress change associated with human activity (Boroumand and Maghsoudi, 2016). The maximum magnitude of induced earthquakes is smaller than what is seen with natural earthquakes (Metz et al., 2017); they tend to occur in swarms (Metz et al., 2017); and occur at shallower depths than natural earthquakes (Gomberg and Wolf, 1999; McNamara et al., 2015; Metz et al., 2017), which may explain why they have been reported to be felt at surface (Boroumand and Maghsoudi, 2016) though they are small in magnitude.

Abstract: Post-migration coherent noise removal by dip decomposition to enhance subsalt imaging

In the Gulf of Mexico (GoM), with complex salt geometry, it is not unusual to see coherent noise in subsalt imaging. Such noise is detrimental to subsalt exploration and appraisal as they often lead to incorrect interpretations.

Abstract: Enhancing salt and subsalt imaging in deep water, Gulf of Mexico, with common offset RTM

We focus on extracting new value to previously acquired orthogonal WAZ surveys in the Mississippi Canyon area where some of the largest and still active deep water discoveries reside. Some analyses estimate that many large subsalt/presalt fields can still be discovered.

Abstract: Salt modeling challenges and strategies in Mississippi Canyon, Gulf of Mexico

In Mississippi Canyon a unique characteristic of salt geometries are their stacking hourglass shapes – autochthonous Louann salt forms the lower part, allochthonous Mesozoic salt forms the middle part, and Cenozoic salt canopy forms the shallow part.

The CSEG RECORDER – Then and Now
The CSEG RECORDER – Then and Now

In September 1985, the first edition of the RECORDER was launched. Having evolved from our humble CSEG member newsletter, the RECORDER has grown into a well-received and respected publication within both the energy and geophysics fields. Like the industry around us, the RECODER continues to evolve to meet the needs of our readers.
