Apparently Mr. Gold didn't speak to any oil field hands that were involved in the massive amounts of frac'ng that was done decades before the recent period he focused on. And that includes multistage fracs in horizontal wells. The technology was readily available long before the recent shale boom. What was missing was a higher price of oil required to justify its application:
"The definition of a massive hydraulic fracturing varies somewhat, but is generally used for treatments injecting greater than about 300,000 pounds of proppant.] Pan American Petroleum applied the first massive hydraulic fracturing treatment to a well in Stephens County, Oklahoma in 1968. The treatment injected half a million pounds of proppant into the rock formation.In 1973, Amoco introduced massive hydraulic fracturing to the Wattenberg Gas Field of the Denver Basin of Colorado, to recover gas from the l ow-permeability J Sandstone. Amoco performed the first million-pound frac job, injecting more than a million pounds of proppant into the J Sand of a well in Wattenberg Field. The success of massive hydraulic fracturing in the Wattenberg Field of Colorado was followed in the late 1970s by its use in gas wells drilled to tight sandstones of the Mesaverde Group of the Piceance Basin of western Colorado.
Starting in the 1970s. thousands of tight-sandstone gas wells in the US were stimulated by massive hydraulic fracturing. Examples of areas made economic by the technology include the Clinton-Medina Sandstone play in Ohio, Pennsylvania, and New York; the San Juan Basin in New Mexico and Colorado; numerous fields in the Green River Basin of Wyoming; and the Cotton Valley Sandstone trend of Louisiana and Texas."
And horizontal well frac'ng: "The combination of horizontal drilling and multistage hydraulic fracturing was pioneered in Texas’ Austin Chalk play in the 1980s. Stephen Holdich, head of the Department of Petroleum Engineering at Texas A&M University, commented: “In fact, the Austin Chalk is the model for modern shale development methods.” The Austin Chalk play started in 1981 with vertical wells, but died with the decline in the oil price in 1982. In 1983, Maurer Engineering designed the equipment to drill the first medium-range horizontal well in the Austin Chalk. Horizontal drilling revived the play by increasing production, and lengths of the horizontal parts of the wellbores grew with greater experience and improvements in drilling technology. Union Pacific Resources, since absorbed by Anadarko Petroleum, entered the Austin Chalk play in a major way in 1987, and drilled more than a thousand horizontal wells in the Austin Chalk."
In the early 90's horizontal drilling in the oil window of the Austin Chalk was the biggest play on the planet. FYI: essentially the Austin Chalk is a carbonate shale. The same hz drilling equipment used in the recent shale play was used in the 90's. And the frac trucks used date back at least to the 80's.
