Index / Gas Shales / Development Technology, Hydrofracking

Clean burning natural gas is critical to American manufacturing jobs, to farmers for fertilizer, to households for heating and cooking, to businesses for electricity and fuel for transportation needs, and to society to help address climate change concerns because of its low carbon-content. But getting to the natural gas isn’t always easy. That’s where hydraulic fracturing plays an important role in America’s energy supply. Hydraulic fracturing is a proven technology used safely for more than 60 years in more than a million wells. It uses water pressure to create fissures in d... More →

Sabrina Eaton reports that a long-awaited U.S. EPA study has concluded that hydraulic fracturing, a technique for oil and gas extraction commonly called fracking and used widely in U.S. , can damage groundwater.

The final version of the report, which has been in the works for five years, reverses earlier drafts that said there was no evidence fracking systemically contaminates groundwater.

Groundwater problems can occur near old, abandoned oil and gas production wells, and ranged in severity from temporary changes in water quality to contamination that made drinking water... More →

Dr. Conca reports that Governor Cuomo announced last year that hydraulic fracturing would be banned in the State of New York, he cited the lack of scientific data on public health effects. He also said more study needed to be done to determine where emissions were coming in the fracking and extraction cycle.

That study has now been done. Chemists at the University of Texas at Arlington published a study that indicates that contamination from fracking wells is highly variable but results more from operational inefficiencies than from the extraction process itself. In other words, it ... More →

Approval of Cuadrilla applications would be a boon for Britain's nascent shale gas sector. The prospects for British shale gas firms got a boost today as a local planning officer in Lancashire recommended a proposed fracking program should be approved.

Fracking is deemed legal in the UK, subject to planning and environmental approval, though operations have been minimal thus far. Cuadrilla is at the vanguard of the UK nascent shale industry and it has been pursuing applications for two separate fracking projects near Blackpool.

Decisions were previously deferred in Janua... More →

This post is one of a series of tech talks, describing some of the ways in which fossil fuels are produced. In the current part of the series we are focusing a little more on the procedures that are being used to recover natural gas from formations such as the Barnett, Fayetteville, Marcellus, Haynesville and Woodford shales. In this particular post we concentrate more on the benefits of horizontal drilling through these shale reservoirs, rather than using the more conventional vertical wells that were used historically. This, and the next three posts in the series, are likely to be a bit more... More →

The issue of hydraulic fracturing has raised many concerns from the public as well as government officials. This paper will review the history and evolution of hydraulic fracturing, including environmental & regulatory considerations. Additionally, technical and environmental considerations will be presented applicable to hydraulic fracturing in the unconvent... More →

Knowledge of the pore structure of gas shales and other micro-porous rocks is of critical importance in establishing the original gas in place and flow characteristics of the rock matrix. Methods of measuring pore volume, pore size distribution, sorptive capacity, and flow characteristics of shales inherited from the coalbed methane and conventional reservoir rock analyses, although widely applied, are of limited value in characterizing many shales and may yield erroneous results. The use o... More →

By Julia F. Gale, Robert M. Reed, Stephen P. Becker, and Walaa Ali, Bureau of Economic Geology, Jackson School of Geological Sciences, The University of Texas at Austin, Austin, TX.

This study describes several sets of natural fractures in a Barnett Shale core from Pecos County, including partly open fractures, fractures associated with chert layers, and early deformed fractures. These are compared with fractures previously described in the Barnett Shale in the Fort Worth Basin. The steep, narrow, calcite-sealed fractures that are present in many Barnett cores in the Fort Worth Basi... More →

A new technique to spot contamination of shallow groundwater has been devised by a team of researchers from the Universities of Edinburgh and Glasgow, and the Scottish Universities Environmental Research Center. The new technique can be used to track the contamination caused by unconventional gas extraction methods like fracking.

This new development could also help to regulate the safety of coal-bed methane extraction as well as shale gas extraction, which have raised concerns regarding contamination of groundwater.

One of the techniques adopted for shale gas extraction ... More →

The EPA Science Advisory Board concludes that EPA should provide quantitative analysis that supports its conclusion that hydraulic fracturing has not led to widespread, systemic impacts on drinking water resources. Most Panel members also conclude that the statement requires clarification and additional explanation (e.g., discuss what is meant by any observed change in the definition of impact in Appendix J, and consider including possible modifying adjectives before the words widespread, systemic impact in the statement on page ES-6).

Four of the 30 Panel members find that this st... More →

Maximize shale gas production: Unlocking the true potential of each wellbore requires an integrated drilling, evaluation, and completion program that takes into account the vertical and lateral heterogeneity in all shale reservoirs. Experience in thousands of shale gas wells has taught Schlumberger that when you account for heterogeneity you maximize production, decrease cost, reduce risk, and ultimately tap into more productive intervals.

Among the statements and assertions made by American Rivers, there are several technical and misleading inaccuracies that must be corrected. First, American Rivers indicates that about 1.5 times the annual flow of the Susquehanna River will be used to sustain natural gas drilling. This is misleading because it implies an ongoing extreme demand for water that in reality will be drawn out over the course of 2 to 3 decades. Further, the estimate includes water needs for wells drilled outside the basin that will not rely on basin water. The Susquehanna River supplies the Chesapeake Bay on averag... More →

Vikram Vishal, Nikhil Jain and Trilok Nath Singh report that the modeling of conjugate development of fractures and fluid flow remains a significant subject in a diversity of rock engineering. Continuum numerical methods are paramount in the modeling of rock engineering practice problems, merely with restrained capacities in modeling the problem of fracture development coupled by fluid flow.

There exists a demand for them to be understood in details. Driven by this, we demonstrated an approach based on a three-dimensional development of fracture of an abstract model condensed to tw... More →

U.S. Energy Secretary Steven Chu said Friday he would not favor a ban on "fracking," a now-common drilling method that XTO Energy (XTO) and other natural-gas companies use to produce gas from hard shale-rock formations that have recently become a major source of natural gas.
