How to Prospect for Oil

June 30, 2014 by · Leave a Comment 

Oil prospecting requires coordination of geologists and engineers to measure potential oil fields for volume.

The film “There Will Be Blood” opens with a small team of men at the turn of the century. They are using a steel bar to drive into the ground, with the hope of finding oil in a deep ditch. Today, our methods are a little different, but the science is quite similar.

Surface Visibility

The first thing a prospector looks for is some evidence on the surface that there is oil down below. Common giveaways include oil seeps, natural gas leaks, and pockmarks in the soil. This kind of visual inspection isn’t just relegated to the past, even though prospectors do rely on complex equipment for most prospecting today.

Seismic Surveys

A seismic survey is the most common method of hunting for oil. Geologists use surveys to detect large-scale features of what’s below-ground. A geologist might use sound, for instance, to get a radar-like layout of the cavity below the earth and use that readout to judge if oil could be present.

Pressure Sensing

Once a well has been identified, a small exploratory drill is done. In this phase, geologists will use oil pressure sensing within the drill to measure the volume of oil beneath the ground. This important sensor measures the pressure within the cavity, determining how much oil might exist based on those readings.

Final Thoughts

Make no mistake. Oil prospecting is still an expensive operation that carries significant risks to all involved. Oil can make companies a lot of money, but it can be a hassle to find and get to. A downhole pressure sensor can help identify whether oil might exist, but it won’t tell engineers anything about the rocks or the land. These important factors must all be considered before a drill ever enters the earth.

We All Need Electricity

There is no denying of the fact that people depend on power and electricity. We all get sad if there is a blackout because then we would not be able to carry on our usual activities like watching television, playing on the computer or even surfing the net. But these are not the only thing we do with electricity or power. The possibilities or opportunities that we can use power with are endless. In fact, many companies depend so much on power because their whole factory is run on power. Their offices cannot function if they lacked electricity because tasks or duties of the people will not be done appropriately without it. That is why it is very important to have ground power unit because this is a source of electricity used by companies in order for them to attain electricity and power. All the different machines in the office is run by electricity. The fax machines, the photocopy machine, computers and so much more! Imagine if you went to work and there was no electricity. How else will you be able to do your jobs and duties? It is good also to keep around lithium batteries that can easily be used right away. These will come in handy just in case of an emergency. If there is a blackout and it is already dark out, you will need the batteries for your to work your flashlights, which will help you find your way out or on your way home.

If you visit stores that make ground power units, you will find many useful products that will help you have portable power. They also have a number of products that are useful like turbine starting.
