Seismic Data and Finding Oil
Much of the energy that we use in our homes each day relies on the gas and oil that has been found and extracted by teams of people. Scientist and engineers like those at Weatherby Energy use whatever information they can when it comes to making an assessment about certain areas and whether they hold enough gas and oil to make it worth drilling for. Geologists, like those on the team at Weatherby Energy look at the physical formation of a particular area to identify folds of hydro=carbon, indications that the area may have some significance to those teams that are searching for oil. Nowadays experts can look beyond what is seen by the naked eye when they are assessing a certain area by using what is known as seismic data.
Seismic date is in the form of images and rather like a CAT scan that is used to detect cancer in people, the images are generated by sound waves. The way in which these are generated in the search for oil is through the detonation of explosives that are planted in deep holes in the ground. The explosion generates waves of sound and scientists like those at Weatherby Energy can then analyze the recording of the movement of those waves through the earth’s surface. An indication of what lies beneath the surface is obtained by assessing the strength and speed at which the sound waves are reflected back to the surface, according to experts at Weatherby Energy.
Geologists and meteorologists use seismic data to determine whether a certain area may be subject to earthquakes and what sort of strength the tremors might be. It is also possible to use seismic surveys to find ground water. The team at Weatherby Energy use the data from seismic surveys to identify which land areas may be suitable for drilling for natural gas or for oil, and whether there is sufficient oil to make it worthwhile digging there. In the past people just drilled wherever they found surface oil deposits or formations and continued to drill there until the spot was dry. Technological advances produced other means of discovering what lay beneath the earth’s surface, specifically seismic surveys
Experts at Weatherby Energy say that it is not only easier to find oil using seismic surveys; it is also easier to assess the depth of that oil. A better indication of what lies below the surface of the earth means that less time and money is wasted in drilling an area until it has run dry. The use of seismic data combined with innovative new drilling equipment from the team at Weatherby Energy means that it is not only easier to locate where the oil formations are, it is also possible to enhance the porous nature of the outer walls of a well, thereby producing more oil.
