Exploration for oil and gas in today’s industry differs greatly from even just a few short years ago. New methods to identify reserves enter the market relatively frequently, as do innovations that improve existing exploration tools. Sentry Energy utilizes a number of different methods to analyze prospects, of steady or even strong production as well as the best way to access potential reserves. The oil and gas industry once depended almost solely on visible surface elements such as seeps and pockmarks. In a seep, oil and natural gas trickle onto the surface, where it can be seen or smelled.
A pockmark, which is caused by escaping gas, looks like an underwater crater. Today, however, most oil and gas exploration relies on extremely complicated geophysical technology. Such equipment measures gravity, magnetism, and other factors that detect the presence of hydrocarbons beneath the surface of the earth. Oil and gas explorers call such a potential reserve a lead. The lead becomes subject to even more scrutiny that focuses on the potential size of the reserve and the best way to access it. When Sentry Energy’s analysis indicates that oil and gas may be present, the company terms the site a prospect; a prospect contains a source rock rich in organic materials, such as coal or oil shale. Over hundreds of years, these rocks form hydrocarbons in the presence of high temperature and high pressure. This pressure spurs the mature hydrocarbons, which tend to have less density and more buoyancy than early-stage hydrocarbons, so much of the product migrates upward, while some becomes trapped between rocks and other material. These traps, which must be covered by an impermeable rock often known as a cap-rock, stop the upward migration of the hydrocarbons. Inside the trap, hydrocarbons collect in a reservoir; this reservoir usually comprises sandstone, limestone, or some other porous stone.
