Did you know that oil and natural gas are abundant on our planet? They are some of the most crucial resources that we use every day. But just how is it that these resources are extracted? And what is involved in the process of finding and extracting them? In this article, we will outline three primary methods of oil and natural gas exploration, to help you make an informed decision about whether or not you need the service of an Australia exploration drilling company. The process of determining where to drill is both an art and a science. It starts with inspecting the surface terrain. Detection of faults is critical because they give a hint of structural traps in reservoir rocks. Anticlines are a common form of structural traps which pinpoint deep-water traps. Blackened ground and rainbow films forming on streams are potential indicators of naturally occurring crude oil. Such clues are valuable, though such kind of a site is more likely to have been spotted and explored long ago. Three Ways Geologists Find Hydrocarbons in the Subsurface Geologists use a variety of techniques to locate potential deposits of oil and natural gas. First, they have to consider where oil and gas originate. They are usually found in deep marine sediments like shale rocks. As such, earth scientists will begin by searching for shale in one of the following methods. Remote Sensing- RS Remote sensing uses aerial photography or satellite imagery to identify surface features. This allows geologists to view large areas on the ground. From hundreds of miles above, images can reveal features as small as a few feet. Satellite imagery can also reveal differences in soil type, moisture level, and vegetation and mineral distribution. The explorers will then use these subtle variations to connect the dots. Geophysical Techniques Geophysical techniques explore petroleum deposits by analysing such factors as density variations, electrical currents, geochemical relationships, heat flow, and gravitational and magnetic anomalies. Seismic prospecting is part of this process, whereby vibrations are induced by a sound-generating machine or explosive charger to study the subterranean rock as deep as 300,000 feet BGL. Wildcat Wells Wildcat wells are drilled in new sites without an existing well and generally in an unexplored areas. They help to identify undiscovered oil and gas. Approximately 10% of wildcat wells arrive at hydrocarbons, but very few identify economically viable amounts. The wells are bored at smaller diameters to save costs. There is a good chance that you have a few pieces of equipment available even though drilling isn’t your forte. However, a professional Australia exploration drilling company offers a host of options, including modern tools and techniques that are more efficient. Perhaps a geologist has explored your site and discovered hydrocarbons beneath the surface. You need special equipment to do the job right the first time and prevent damage. Your project will be done in a timely fashion so you can stay on schedule.
