Oilfield Fuel Tank Polishing In The Shale Oil And Gas Industry

By Iva Cannon


There are millions of tanks all over the world in an almost infinite number of industries, including oil exploration and production. They are being used for transportation, storage, processing and more. From time to time, each and every one of these millions of tanks has to be cleaned. Most of them are located outdoors in places like oilfields, where there is no access to a pump or other oilfield fuel tank polishing equipment. Companies have developed solutions like portable, diesel-powered pumps to make the job easier. As horizontal drilling for shale oil and gas reserves continues to grow, the demand for clean tanks will increase.

Thanks to new technologies enabling horizontal drilling and hydraulic fracturing, vast reserves of previously inaccessible oil and gas are now being drawn from tight, fine-grained, sedimentary, shale rock formations beneath the earth's surface. Without these resources, existing reserves would only provide sufficient energy for our needs for the next ten years.

Following 40 years of exploring shale oil and gas reserves, America now has enough fuel for the rest of the 21st century. It has also been able to cast off the shackles of relying on capricious foreign powers for its oil supply. This gain has not been without controversy. Hydraulic fracturing, playfully abbreviated to "fracking, " raises concerns of triggering earthquakes and contaminating public water supplies.

The process of hydraulic fracturing involves drilling a hole deep into the Earth's crust into underlying shale rock formations and then powerfully forcing a slurry of sand, water and chemicals into the rock to create fractures through which gas and oil flow up to the surface once the downward pressure is released. There are so far seven main shale oil plays throughout the country. These are: Marcellus, Granite Wash, Eagle Ford, Niobrara, Andarko-Woodford, Bakken and Permian.

Slightly more than half of the investment in these seven fields is going into two major plays: Eagle Ford and Bakken. Wells of the Bakken shale play, located in Western North Dakota and Eastern Montana, are approximately 10,000 feet deep. The brittle and easily-harvested shale formations of Eagle Ford in Southern Texas produce at depths between 4,000 feet and 14,000 feet.

About 25 percent of the oil and gas E&P investment has been poured evenly into wells in the Marcellus Shale and Permian Basin. The Permian exists in western Texas and eastern New Mexico. It contains the thickest deposits of the Permian geologic period, hence the name. The Marcellus Shale is found in Pennsylvania. This is one of the most shallow deposits, drilled to a depth of only 6,300 feet.

The remaining fraction of the shale oil investment pie is divided amongst Granite Wash (Oklahoma-Texas panhandle), Andarko-Woodford (Oklahoma), and Niobrara (Nebraska). Granite Wash reserves are the deepest reserves, at approximately 15,000 feet.

Road traffic deaths have dramatically increased in both the Eagle Ford Shale and Permian Basin. In 2014, a total of 696 drivers were killed and there were 8,600 serious accidents in which occupants were either killed or seriously injured. More serious accidents occur in the hour around 5 a. M. Than any other time of day. This is largely attributable to collisions between ordinary vehicles and 18-wheelers.
