Challenges for microseismic monitoring

We review important challenges in microseismic monitoring and interpretation of the microseismic events. We start with locations of microseismic events and the impact of temporal changes in velocity during hydraulic fractur...

Downhole microseismic monitoring of shale deposits: Case study from Northern Poland

Microseismic monitoring has become a standard technique to map the development of hydraulic fracturing. This study is a case study of a downhole monitoring detected a large number of microseismic events indicating successful develop...

Microseismic signatures of hydraulic fracture growth in sediment formations: Observations and modeling

We analyzed a microseismic data set from hydraulic fracture simulation of the gas field in west Texas. We used an automated wave-picking algorithm and obtained a high-density image of induced microseismic events accompanying the hyd...

Microseismic data interpretation – what do we need to measure first?

Currently, there are four widely discussed theories used to describe how microseismicity interacts with hydraulic fracturing. Each theory has a different implication for the interpretation of microseismicity used for reservoir model...

Microseismic monitoring in early Haynesville development

Microseismic monitoring enabled optimally orient wals for development in Haynesville shale play. Hanesville due to its depth and petting was mainly developer through surface monitoring with burrit arrays....

Microseismic activity of the Upper Morava basin and surroundings

This paper deals with description of microseismic activity of the Upper Morava basin and surroundings. The results of the monitoring period 1996-2007 show a regional-scale focusing of microseismic activity within a 40-60 km wide Nys...

Directivity of microseismic events as a tool for interpretation

to describe how microseismicity interacts with hydraulic fracturing. Each theory has a different implication for the interpretation of microseismicity used for reservoir modeling. Therefore, better understanding of the relationship...

Feasibility of jointly locating microseismic events with data from surface and downhole receivers

Using synthetic data we study the feasibility of locating microseismic activity with both surface and downhole receivers as compared to the use of surface receivers only....

Investigating the time clustering of induced microseismicity generated by hydraulic fracturing

By using the global and local coefficient of variation and the Allan Factor we investigated the time-clustering properties of the time dynamics of fluid-injection–induced microseismicity. The applied methodology cane discriminate between fault ...

The differences in detectability of perforation shots and microseismic events in the surface monitoring: the attenuation effect

microseismic events, in the surface monitoring recordings it is often opposite. We investigated amplitude spectra of microseismic events and perforation shots in the downhole-200 Hz are stronger for the microseismic events...
