A Fix for Fracking the Marcellus Shale

Total Engineering introduces the Top Side Collider an associated name and long term fix for fracking the Marcellus Shale and many of the others shale’s’ being drilled into today for natural gas.
The migration of the gases and fluids into the fresh water sands occur because of the lack of a good cement bond. And that thought process covers a lot of ground. No one is to blame because good oil field practices have been in place. The problem has been that a new understanding and a new design of cementing must come along because of the age of the deposition of the rocks and shale.
The Marcellus shale is part of the geologic time Period called Pennsylvanian. http://en.wikipedia.org/wiki/Marcellus_Format... http://en.wikipedia.org/wiki/Geology_of_Penns... http://en.wikiversity.org/wiki/Pennsylvanian_...
Open the sites above and take a look around. The outcropping of the Marcellus shale clearly shows that it is an unconsolidated formation. Meaning that bonding material was not present during that time of death of the plants and then erosion. But the Marcellus shale is not the reason the gases and fluids have migrated from about 8,000 feet below surface up to the fresh water zones of about 500 feet. That has occurred for the lack of good cement bonding.
There may be some changes that could come down hole at the 7,000 to 8,000 feet level but the main source of the problem is the string of pipe set through the fresh water zone for protection from surface down to about 500 to 700 feet is allowing the down hole migration.
That was our focus and to which our Patent has a fix.
We will sell our patent soon; we have a very large oil and gas service company that is in the evaluation stage.
