US Coast Guard Plans To Transport Fracking Wastewater Via Barge

frackingwastewaterbarge

The United States Coast Guard in seeking input from the public regarding a proposal that will allow barges to transport shale gas wastewater.

Currently, fracking wastewater is stored at drill sites or transported by truck or train to treatment plants. Barge companies are interested in taking wastewater to disposal sites in Texas and Louisiana.

The well pad

The average well pad is a cleared, graded and gravelled are of approximately four to seven acres on which the drilling and hydraulic fracturing operation takes place. The well pad has developed from supporting a single well to becoming a multiple well operation, and being able to support up to 12 natural gas wells. Concentrating the ecological footprint of a larger number of wells and their associated pipelines, roads and infrastructures in one single pad, greatly reduces the environmental impacts of drilling. While there has been a definitive increase in multi-well pads the majority of pads today are still single pads. The average pad to well ratio in Pennsylvania Marcellus wells in 2010 was 2.15 with an increasing tendency[1].

A typical well pad houses the well itself, water storage facilities and space for the mobile blender facility, sand storage units, pump trucks, chemical trucks and staff infrastructures[2]. The well head is connected to the casing in the ground which, once fracturing is completed, directs the gas to the different surface facilities. From the well head the gas is initially directed into a sand trap and separator which separates sand and water away from the gas. Once separated the produced water is pumped into wastewater tanks on the well pad where it is stored until it is hauled off and disposed[3]. Continue reading “Associated Infrastructures”

What is Fracking?

Hydraulic fracturing, or fracking, is a method of extracting oil and natural gas from shale rock formations located deep below the surface of the Earth.

Fracking allows for oil and natural gas to be extracted from rock formations that elude traditional forms of drilling.  It is the creation of cracks and ruptures within rock layers via the injection of pressurized fluids and particles. Continue reading “What is Fracking?”
