Sentry Energy Production LLC is a privately held oil and gas exploration and development company.

Addison, Texas

Based in Addison, Texas, Sentry Energy Production LLC has built a reputation for its research-driven, intelligent approach to oil and gas exploration and development. The business model of Sentry Energy Production LLC was designed to allow its partners to balance or diversify their existing portfolios by entering the oil and gas industry while simultaneously selecting proven or geologically lower-risk speculation areas that increase the likelihood of a return to its partners. Using detailed research, Sentry Energy Production LLC identifies existing areas with a history of oil and gas production that might be considered “dry” and works to extract further resources from them with the help of new or enhanced technology. One example of the company’s due diligence in identifying wells is its work with the McCracken Prospect in Ness County, Kansas, which was plugged in 1998 after determination that it was “dry.” Using 3-D seismic visualization, Sentry Energy Production LLC determined that additional oil could be recovered from the acreage. By working with a proven property that already has infrastructure in place, Sentry Energy Production LLC is able to cut costs significantly while simultaneously improving the odds that oil will be produced. Sentry Energy Production LLC also occasionally works with new well development, identifying less expensive, geologically lower-risk areas worthy of speculation.

Sentry Energy Production LLC specializes in extracting oil from wells previously thought to be dry. In this pursuit, Sentry Energy relies on a variety of innovative techniques, as well as solid, time-tested strategies.

Shale gas is natural gas that has been trapped within shale formations. A fine-grained, sandy sedimentary rock, shale forms when silt and clay particles are compressed and heated. As one of the so-called “mudstones,” shale differs from the pack due its many thin, laminated layers, and the way in which these layers split apart easily.

Extracting oil or natural gas from shale costs more than extraction from some other deposits because of the increased processing, but shale gas has rapidly become a greater energy source in the United States in recent years. According to a newer study conducted by the Massachusetts Institute of Technology, natural gas may well double its share of the energy market, reaching 40 percent by the year 2050. Over the last 10 years, energy companies have increased the amount of natural gas they can extract from shale through techniques, including horizontal drilling and hydraulic fracturing.

Shale plays are the formations which hold shale gas. The United States features a particularly rich quantity of these plays, with some researchers suggesting that enough shale gas exists in the country to provide for more than 100 years of use. One important play in Texas, known as the Barnett Shale, has produced a substantial amount of shale gas in the past decade. Oil and gas prospectors and processors have learned much from their work in the Barnett Shale, as well as the Marcellus, Utica, Haynesville, and Fayetteville Shales across the United States.
