Unconventional Reservoir – Hydraulic Fracturing

Posted: 09 Oct 2011 02:01 PM PDT

This video comes from Chesapeake Energy that demonstrates how hydraulic fracturing works in unconventional reservoir. The purpose of fracturing the shale formation is to maximize production potential of the well. The material used in fracturing is a mixture of water and proppant, usually sand. This mixture of liquid and sand is pumped in to the newly created perforation and shale formation.

Barrel of Oil Equivalent

Posted: 09 Oct 2011 10:07 AM PDT

Barrel of Oil Equivalent (BOE) is used by oil and gas firms in their financial statements as a method of combining oil and natural gas reserves and production into a single measure.

According to USGS, one BOE is roughly equivalent to 6,000 cubic feet (170 cubic meters) of typical natural gas. In short, 1 BOE = 6 MCF or 1 MBOE = 6 MMCF or 1 MMBOE = 6 BCF.
