I read with interest about the panel discussion on the pros and cons of so-called “hydrofracking.” The debate as framed makes good points, however, it also misses a few key points.
When I was an exploration and development geologist for a Fortune 100 oil and gas company, for all the majors I worked with the preferred industry standard practice for both oil and gas well completions was called an “acid frac,” or an “acid job.” Based on my understanding, this is still the preferred method for non-horizontal wells, not hydrofracking.
The acids pumped into these wells, such as hydrofluoric and hydrochloric acid, are highly concentrated to “clean out” or dissolve rock and natural cements to produce preferential flow paths for oil and gas. These old practices involve hundreds of thousands of U.S. wells—more than are typically hydrofracked. These practices are unregulated, as are the drilling muds.
“Mud” is a misleading term. These muds are laden with polymers, chemicals, and heavy metals formulated to bring to the surface crushed rock, coat the borehole, and prevent blowouts. My company experienced a “blowout” in Oklahoma that blew the entire drill string out of the hole when it encountered an over-pressured gas zone and the mud was not thick enough to counter the massive pressure. Muds are excluded from reporting, regulation or oversight.
The key to a successful well is the completion method: the type of mud used and how the well casing is cemented into place. The blow-out of BP’s Deep Water Horizon Anaconda well in the Gulf is a recent case of questionable cementing practices. There was also a major blowout several years prior in Ohio.
Well-drilling and completions are not regulated, left up to what is termed “best professional practice.” Yet large areas and groundwater zones in many old producing areas in the U.S. are contaminated from prior practices. This calls for a broad-based effort by citizens and government to reduce deaths and injuries. Despite best practices, accidents do happen.

Over Labor Day Weekend, from Aug. 29-Sept. 1, the American Airpower Museum in East Farmingdale, treated Long Island locals to a once in a lifetime experience, taking visitors high above the clouds during its Warbird Weekend: Salute to Airpower.
To kick off the celebration, on Aug. 28, tens of thousands of Long Islanders who worked in local defense plants, but were never given an official “thanks” for a job well done, were honored by the Museum.

Sometimes when you do a job for a customer, you really have to expect the unexpected.
In the case of German Cabral and Jason Galvin, energy efficiency advisors with the Farmingdale-based Green Homes Long Island, this was just the case. Who could have imagined that while trying to figure out the best way ot lower a client’s energy bills they would solve a 20-year-old mystery?
On Aug. 20, certified energy efficiency experts did a home energy audit for Plainview resident Seymour Bosworth, with the goal of lowering the homeowner’s energy use by 25 percent or more.

The 2014 Farmingdale Flag Football season kicked off with a blast on Sept. 7.

The Texans and the Jets played a great opening weekend game, with the Texans getting the victory. For the Texans, touchdown pass from Joseph Spano to Jaxon Parisi with 20 seconds in the half broke a tie that the Jets never came back from. The Jets were led by Brendan O’Keefe, who had two rushing touchdowns and Jimmy Caputo, who picked off a pass at the goal line.
