Young 1116 Shoal Creek Road | Burnsville | NC 28714 Property Location: 4075 Hwy 19E | Burnsville T:828.208.0006 1|P a g e COUNTER OFFER TO SUMMARY/OFFER TO PURCHASE REAL PROPERTY Submitted to the State of North Carolina Department of Transportation OVERVIEW Retail gasoline businesses, such this gas station and convenience store, are single-purpose economic enterprises. Because of their specialty of design, they cannot be readily converted to other types of businesses without a significant loss in value. Gas station convenience stores are special-built properties designed to make money in only one way, and they are not easily adapted to other uses. These businesses derive a significant part of their gross sales, about 50 percent, from the sale of motor fuels (National Association of Convenience Stores, 2006). The Silver Bullet recorded at one time 77% of gross sales from the sale of gasoline. This business also sold propane and kerosene (2000 UST). This site has (1) 8,000, (2) 6,000, and (1) 2000 gallon warranted (40 yrs) USTs for fuel (installed by Southern Tank & Pump, NC). stations, and canopies, which are situated on-site but separate from the building. Design features create and significantly influence the property value. For example, the fuel service is so specially-designed that if it becomes no longer profitable...

Shale gas is natural gas from shale formations which acts as both the source and the reservoir for the natural gas. Each Shale gas reservoir has unique characteristics. Shale has low matrix permeability, so gas production in commercial quantities requires fractures to provide permeability. For a given matrix permeability and pressure, gas production are determined by the number and complexity of fractures created, their effective conductivity, and the ability to effectively reduce the pressure throughout the fracture network to initiate gas production. Understanding the relationship between fracture complexity, fracture conductivity, matrix permeability, and gas recovery is a fundamental challenge of shale-gas development. Shale gas reservoirs almost always have two different storage volumes (dual porosity) for hydrocarbons, the rock matrix and the natural fractures .Because of the plastic nature of shale formations, these natural fractures are generally closed due to the pressure...

...In physics and chemistry, plasma is a state of matter similar to gas in which a certain portion of the particles are ionized. After sufficient heating a gas dissociates its molecular bonds, rendering it into constituent atoms. However, further heating may also lead to ionization (a loss or gain of electrons) of the molecules or atoms of the gas, thus turning it into a plasma, containing charged particles: positive ions and negative electrons.[1] The presence of a non-negligible number of charge carriers makes the plasma electrically conductive so that it responds strongly to electromagnetic fields. Plasma, therefore, has properties quite unlike those of solids, liquids, or gases and is considered a distinct state of matter. Like gas, plasma does not have a definite shape or a definite volume unless enclosed in a container; unlike gas, under the influence of a magnetic field, it may form structures such as filaments, beams and double layers. Some common plasmas are stars and neon signs. In the universe, plasma is the most common state of matter for ordinary matter, most of which is in the rarefied intergalactic plasma (particularly intracluster medium) and in stars. States of matter are the distinct forms that different phases of matter take on. Solid, liquid and gas are the most common states of matter on Earth. However, much of the baryonic matter of universe is in the form of hot plasma, both as rarefied interstellar medium and as dense stars. Historically, the distinction...

Reservoir

...World Shale Gas and Shale Oil Resource Assessment   SHALE GAS AND SHALE OIL RESOURCE ASSESSMENT METHODOLOGY INTRODUCTION This report sets forth Advanced Resources’ methodology for assessing the in-place and recoverable shale gas and shale oil resources for the EIA/ARI “World Shale Gas and Shale Oil Resource Assessment.” The methodology relies on geological information and reservoir properties assembled from the technical literature and data from publically available company reports and presentations. This publically available information is augmented by internal (nonconfidential) proprietary prior work on U.S. and international shale gas and shale oil resources by Advanced Resources International. The report should be viewed as an initial step toward future, more comprehensive assessments of shale gas and shale oil resources. As additional exploration data are gathered, evaluated and incorporated, the assessments of shale oil and gas resources will become more rigorous. RESOURCE ASSESSMENT METHODOLOGY The methodology for conducting the basin- and formation-level assessments of shale gas and shale oil resources includes the following five topics: 1. Conducting preliminary geologic and reservoir characterization of shale basins and formation(s).  2. Establishing the areal extent of the major shale gas and shale oil formations.  3. Defining the prospective area for each shale gas and shale oil formation.  4. Estimating the risked shale gas and shale...

Property Owners: Texas Supreme Court Case Study

...Property Owners The first group of stakeholders that needs to be represented in this debate is property owners, specifically property owners who also have natural gas under their property or experience environmental and property damage from fracking. Matt Willie addresses the conflict of private property and gas companies. He summarizes that the main issues involved with hydraulic fracturing and property rights are trespassing, pooling, ownership, and damages (Willie, 1752). For trespassing, the issue that has arisen is whether horizontally drilling under someone else’s property is trespassing (1752). The author then concludes that based on the Texas Supreme Court case Coastal Oil and Gas Corp. v. Garza Energy Trust, extracting gas or oil...

Risk Management

...9-201-113 REV: AUGUST 27, 2001 D O LISA MEULBROEK Risk Management at Apache N Introduction O By March of 2001, managers at Apache Corporation, an independent oil and gas exploration and production company, had reason to be optimistic. While oil prices had softened somewhat recently, at $27 a barrel they were much higher than the pernicious levels of 1998, when oil bottomed out at $11 per barrel. Apache had just closed on the acquisition of Repsol in Egypt's Western desert and, along with its partner Shell Overseas Holdings, had also acquired Fletcher Challenge Energy, for a combined cost of $1 billion. The value of such acquisitions, however, depended in large part on the future prices of oil and gas. To decrease its exposure to oil and gas price volatility, Apache had begun a limited hedging program centered mostly on its recently acquired properties. Apache’s managers knew that hedging could create its own risks, and so it seemed prudent to re-evaluate the success of the new program. The decision facing Apache’s managers was whether the firm should continue hedging, and if so, should its current program be extended beyond hedging the revenues from acquisitions? T CO Apache Corporation PY Apache Corporation was founded in 1954 by Raymond Plank, its current Chairman and Chief Executive Officer. Mr. Plank’s son, Roger, was the company’s current CFO, but the company was not controlled by the Plank family, and in fact, officers and...
