“The mechanical principles of fracking have not changed since the first brave shooter dropped an explosive charge down a well in the 1860s. Then as now, the task is to deliver a powerful force to a designated depth underground, rubblizing the hard rock formations around the well to stimulate the release oil or gas trapped within….”
“The well shooter’s original tools of choice were gunpowder and, later, liquid nitroglycerin…”
I laugh as protecting the special secret sauce has its orgins too, “….defending his patents from operators who took to fracking under cover of night to avoid Roberts’ royalties. One explanation for the origins of the term “moonlighting” comes from this rogue practice.
Commercial Fracking Explodes
According to a 2010 fracking history by the Society of Petroleum Engineers (SPE), the idea of non-explosive alternatives to nitroglycerin took root in the 1930s. Experiments through the next decade paved the way for the first industrial-scale commercial uses of the modern patented “Hydrafrac” process in 1949, with Halliburton holding an exclusive license in the early years. SPE recounts that 332 wells were fracked in the first year alone, with up to 75 percent production increases recorded. By the mid-1950s, fracking hit a pace of about 3,000 wells a month.
A typical early fracture took 750 gallons of fluid (water, gelled crude oil, or gelled kerosene) and 400 lbm of sand. By contrast, modern methods can use up to 8 million gallons of water and 75,000 to 320,000 pounds of sand. Fracking fluids can take the form of foams, gels, or slickwater combinations and often include benzene, hydrochloric acid, friction reducers, guar gum, biocides, and diesel fuel. Likewise, the hydraulic horsepower (hhp) needed to pump fracking material has risen from an average of about 75 hhp in the early days to an average of more than 1,500 hhp today, with big jobs requiring more than 10,000 hhp.
Fracking’s new golden age began in 2003,….”
So unconventional should be time stamped when?….mid 1950’s? …Texas’ George P Mitchell (aka Father of fracking) 1980’s or 1990’s?….
So which FRACK do they NOT want attacked? Pollution from gun powder, nitroglycerin, gelled crude oil/kerosene…etc (NOTE the ASME report does not mention depleted uranium used in our unconventional perfing gun process).
Some people think that unconventional is when they started drilling horizontally or “directional” drilling. But alas there are historical accounts of accessing/stealing hydrocarbons off of another person’s property by slanted drilling.
Frackers have a history of needing to be jailed in my opinion.
There are also references to the acronym HVHF (High Volume Hydraulic Fracturing).
I once had it explained to me that conventional taps pockets/pools VERTICALLY that are easy to reach than the hydrocarbons trapped in the shale rock they directionally drill for…
A recent profracking article attempting (and failed) to parse out conventional from unconventional “oil” is here…
