The Marcellus Shale Energy and Environment Laboratory (MSEEL) involves a
multidisciplinary and multi-institutional team undertaking integrated geoscience …

Long‐period long‐duration (LPLD) seismic events are observed from a microseismic data
set acquired by surface receivers in the Eagle Ford Shale. These events are characterized …

Recently, oil and gas companies started to invest in fiber optic technology to remotely
monitor subsurface response to stimulation. Distributed Acoustic Sensing (DAS) and …

Low-frequency seismic events of long duration were recorded by a surface array of 48, 3-
component geophones during the fracture stimulation of two offset horizontal wells in the …

Hydraulic fracturing is a well‐established technique to extract gas or liquid hydrocarbons
from low‐permeability formations such as shale and tight gas reservoirs. Diffusion of …

A surface seismic network of five broadband seismometers was deployed in the vicinity of a
CO2 injection well at an active enhanced oil recovery site in Farnsworth, Texas. We …

The oil and gas industry is continually increasing unconventional extraction efficiency in
order to provide hydrocarbon production to meet growing energy needs. Recovery of oil …

Hydraulic fracturing involves the injection of large amount of fluid, typically water, in the
reservoir rock that increases fluid pressure in the pore spaces and alters the stress condition …

CO2-EOR is an attractive enhanced oil recovery (EOR) technique that offers both economic
and environmental benefits–1) CO2-EOR recovers additional oil from depleted reservoirs …

Injection of carbon dioxide (CO) into depleted oil reservoir is an advantageous tertiary
recovery method as it allows for the long-term storage of CO in the empty pore spaces …
