3.1.4. Highlights of Important Results

Between 1976 and 1992, the EGSP catalyzed several innovative industry "firsts" that later became commercial technologies or products. In addition, the EGSP resulted in the acquisition and wide dissemination of an enormous quantity of geologic and production data about Eastern gas shales.

This data led to important new insights into the nature of shale gas reservoirs and the mechanisms behind their production. Highlighted below are the key technology products and E&P methodologies that resulted from the EGSP.

Foam Fracture Technology -- The EGSP was responsible for the first use of nitrogen foam fracture technology in the Devonian Shale in 1975. Prior to this time, shale wells had been explosively stimulated in open-hole well bores (no casing across producing formation) and water fracs had been used to improve production.

Foam fracture stimulation technology allowed sand to be transported by the fracture fluid while simultaneously reducing the volume of water used by 75 to 90 percent as compared to conventional water fracs.

The incremental cost of foam fracs was offset by reduced well cleanup costs and improved productivity. More than 50 cost-shared foam frac demonstrations were conducted with industry during the first four years of the program.

By 1979, foam fracturing was the preferred commercial method of stimulation for Devonian shale gas wells and commercial services were widely available to operators in the eastern United States.

Oriented Coring and Fractographic Analysis -- In 1977 the EGSP carried out the first oriented coring and fractographic analysis of Devonian shale to detect natural fractures.

The use of oriented core was an innovation which allowed not only the detection and location of natural shale fractures, but also allowed for the determination of both fracture azimuth and dip -- key parameters in determining geologic structural trends, gas production mechanisms, reservoir modeling parameters and reservoir anisotropy.

Subsequently, oriented coring and fractographic analysis became commercially available to operators seeking to reduce their risk of drilling underperforming shale wells. Coring techniques developed through the EGSP were also employed in DOE sponsored research related to western tight sands (see Section 3.2). The core analysis techniques developed for identifying natural and core-induced fractures have since been used throughout the US to evaluate low-permeability gas reservoirs.

Devonian Shale Logging Suite -- As part of the EGSP, DOE worked with the well logging service industry to jointly develop an electric downhole well logging suite for air-drilled bore holes, consisting of gamma ray, caliper, compensated density, temperature and noise logs. This suite was developed to permit the determination of lithology and production potential of the shale in air-drilled holes. Most previous logging had required water or mud-filled wellbores, liquids which damaged the permeability of the fluid-sensitive shales. By 1985, a commercially available Devonian well logging suite was being used by industry within the Appalachian Basin.

Role of Adsorption in Devonian Shale Production Mechanism -- The EGSP carried out research that resulted in the recognition of the contribution of absorbed gas and fracture systems to the shale gas production mechanism. Gas desorption data derived from canned samples taken from Devonian shale oriented core collected by the EGSP demonstrated the importance of the desorption mechanism to long-term gas production.

Canned samples from 35 cored wells were used to carry out the first widespread characterization of Devonian shale gas content and to prepare gas resource estimates based on a much improved fundamental understanding of the nature of the shale reservoir rock. Widespread industry knowledge of the role of absorbed gas and the accompanying mechanism for gas flow through a network of interconnected natural fractures permitted the development of more accurate production models that incorporated dual porosity/dual permeability fluid flow in the reservoir. This in turn resulted in better tools for reserve estimates and economic decision-making by industry. The early development of dual porosity reservoir models also paved the way for later work in support of similar models for coalbed methane production.

Downhole Video -- The EGSP carried out the first use of a downhole video camera in the history of U.S. oilfield operations. DOE began the use of downhole video by designing and testing a downhole underwater camera for viewing the wellbore of a Devonian shale well in Ohio, in an effort to identify fractures contributing to gas flow. The service company contractor subsequently opened an office in Ohio and developed a commercial downhole camera service. By 1981, downhole video camera services had been commercialized in the eastern U.S. with multiple companies operating in Ohio, Kentucky and West Virginia.

Large-scale Massive Hydraulic Fracturing -- The EGSP introduced large-scale Massive Hydraulic Fracturing (MHF) to the Eastern Devonian shale marketplace. This type of stimulation, used to place large volumes of sand proppant into the shale formation to lengthen the induced fracture length and increase connectivity with the gas-bearing natural fracture system within the shale, had not previously been employed for stimulating shale wells. By 1990, commercialization of MHF stimulation allowed industry to recognize the benefits of such large scale stimulations in targeted shale areas.

Directional Drilling to Improve Productivity -- In 1975, a pre-EGSP DOE-industry collaborative effort resulted in the first Appalachian Basin high-angle Devonian shale directional well in Mingo County, WV (ultimate inclination of 43 degrees). This was followed up in 1978 with the first EGSP Devonian shale high-angle directional well, a joint well in the Cottageville gas field, Jackson County, WV (ultimate inclination of 52 degrees).

Again, in 1986, DOE and industry partners drilled the first air-drilled horizontal well Devonian shale well in Wayne County, WV, having a total horizontal displacement of 3,186 feet from vertical at a measured depth of 6,020 feet.

Among a number of other "firsts" this well also recorded the first recovery of core from a horizontal, air-drilled Devonian shale well, the first horizontal well where external casing packers (ECP's) were successfully installed and inflated in an air-filled wellbore, and the first horizontal well to complete seven individual hydraulically fractured intervals. In 1989 and 1990, three additional DOE/industry jointly-sponsored Devonian shale horizontal wells were drilled and completed: a 1,789-foot horizontal well (measured depth of 6,399 feet) in Putnam Co., WV, a 1,985-foot horizontal well (measured depth of 6,263 feet) in Martin Co., KY, and a 1,617-foot horizontal well (measured depth of 5,013 feet) in Calhoun Co., WV.

These cost-shared demonstration wells identified the technical barriers to widespread application of underbalanced horizontal drilling in the United States.

DOE's follow-on R&D programs continued to develop new underbalanced vertical and horizontal drilling products and formed the basis of its leadership role in underbalanced drilling.

Electromagnetic Measurement-While-Drilling -- Wells drilled as part of the EGSP saw the first use of electromagnetic measurement while drilling (EM/MWD), where it was introduced as a method for steering downhole motors during drilling of a Devonian shale horizontal well. Initial runs were encouraging and resulted in further tool development.

More than 13 field tests of EM/MWD were conducted during and after the EGSP program and the tools were used commercially in the US mid-continent and west coast as well as in western Canada. Based on this success, DOE's subsequent Natural Gas Supply R&D program continued to fund the research from 1992 to 1998.

Carbon Dioxide Fracture Treatment -- The very end of the EGSP saw the first successful use of CO2/Sand stimulation in Devonian shale wells; a technology introduced into the United States by this program.

A total of five CO2/Sand well stimulations were executed for two operators in Perry and Pike counties, KY.

These tests were funded by the EGSP program in 1991/1992. CO2/Sand stimulation subsequently became one of the stimulation options used in the San Juan Basin on a commercial basis.

Other equally important results of the EGSP that increased the knowledge base related to the Devonian shales and aided in subsequent exploration for and development of this vital energy source include the following:

  • Methods for geologic integration of well logs, core data, geophysical survey results, and remote sensing interpretations into a suite of E&P tools for identifying organic source rocks and detecting enhanced fracture density in the Devonian shales.
  • Basic knowledge gained from the collection of 25,000 feet of oriented core from more than 35 wells and the geochemical, fracture characterization, and detailed lithological analyses carried out on the core.
  • More than 120 detailed maps and cross sections provided to industry as part of the first detailed descriptions of the distribution of high organic content, gas-productive, fractured shales over a large portion of the Appalachian Basin. Structural and stratigraphic maps provided information on the influence that deep basement faulting and tectonics had on the location of shallower faults and fracturing. Present day stress orientations and stress ratios were mapped to identify areas of greatest gas production potential. These data were assembled through an integrated effort of the oil and gas industry, State geological surveys, USGS and DOE contractor efforts. Studies were extended to include organic shales in the Illinois and Michigan Basins.
  • As a result of detailed Devonian shale structure mapping during the EGSP, a northeast-southwest structural fold (anticline) was found in southwestern New York. This trend, which was subsequently extended through northwestern Pennsylvania and into northeast Ohio, is a highly productive, faulted limestone trend (termed the Bass Island trend) located stratigraphically below, but unassociated with, the Devonian shale. Without the detailed structural mapping carried out by the EGSP, this productive oil and gas trend may not have been located.
  • An extensive bibliography related to Devonian shale gas exploration activities in the Appalachian, Michigan and Illinois Basins that was made available to industry through NETL and the state geological surveys.
  • A methodology was developed for integrating data that facilitates interpretation of the history of a basin's development and the potential of the sediments and organic matter to produce petroleum and natural gas. The result, a better understanding of when gas and oil are generated and the geometry of the basin when these fluids migrate, allows industry to identify the areas of highest potential for gas trapping mechanisms as targets for development.
  • Knowledge of Devonian shale production mechanisms developed as part of the EGSP was useful to operators developing the Barnett and Lewis shale resources during the decade following the EGSP.

The DOE was asked to quantify the overall benefits of the EGSP as inputs to the National Research Council report titled "Energy Research at DOE: Was It Worth It? Energy Efficiency and Fossil Energy Research 1978 to 2000" published in 2001. Estimates were calculated for three time periods - the 1978 to 1992 period when the program was active; the 1993 to 1998 period for which data on impacts are available; and, the 1999 to 2020 period based on a projection using the EIA/NEMS natural gas model. The benefit measures used are - annual gas production, additional supplies of natural gas and new well drilling.

The baseline starting point was 1978 with a declining Appalachian Basin shale production industry providing 70 Bcf of annual production, drilling 200 wells per year, and holding a reserve base of 1,000 Bcf. Based on analogs with other natural resource R&D programs (such as the benefits study by GRI's R&D program on coalbed methane in the San Juan and Warrior basins), the DOE EGSP was allocated responsibility for 50 percent of the impact and benefits in the Appalachian Basin during Periods 1 and 2, and 25 percent of the impact during Period 3. This approach considered not only the production that would have occurred in the absence of the program, but also production induced by the existence of Section 29 tax credits under the Natural Gas Policy Act, and incremental production resulting from the R&D activities of the Gas Research Institute.

The knowledge base and technologies developed by the EGSP found ready application in other domestic gas shale basins (e.g., the DOE R&D program undertook the initial R&D effort in the Antrim Shale of the Michigan Basin, which was subsequently pursued by GRI and industry). As a result, the DOE R&D program was allocated responsibility for 10 percent of the impact and benefits in other gas shale basins.

These assumptions resulted in an estimated impact resulting from the EGSP of an incremental 4.17 Tcf in gas supply, 7.83 Tcf in proven reserves and 10,600 wells drilled over the 1978-2020 time period. One of the benefits attributable to the additional gas supplies are the state and federal tax revenues received from the sale of the gas. The dollar value of the benefits from state and federal tax revenue of the EGSP was calculated at $1,040 to $2,080 million using a conservative value of $0.25 to $0.50 per Mcf for the additional gas supplies. Using the total cost of $92 million, the undiscounted benefit/cost ratio would be 10:1 to 20:1, based on incremental tax revenue alone. At current gas prices, the revenue impacts and benefit/cost ratio would be considerably greater. In addition, DOE estimated over $8 billion in consumer savings due to lower gas prices. > National Research Council report found that,
    "The EGSP was responsible for bringing together and integrating a significant amount of scattered data on the Eastern gas shales critical to a solid assessment of the resource base. Such an assessment was, as is always the case, necessary for the optimum deployment of technology. Although the in-place shale gas resource base in the United States is large, it is marginal and produced in relatively small increments. At the time ERDA, and later DOE, began the program in the Eastern gas shales, the conventional wisdom was that any significant expansion of production would require relatively high gas prices and that technology in these formations could do little to substitute for high prices.

    But incentives through tax credits, combined with optimum deployment of advanced technology, served to revive a domestic gas province in decline. In a significant way, technology can and does substitute for price in marginal resources, and the Eastern Gas Shales program proved that critical point."
