Some people say that money goes around the world. Others insist that the main ingredient is love or even music. But whatever drives humanity day in and day out, our dependence on fossil fuels leaves one fact certain: the axis of our globe is full of oil.

Comparing Traditional And Modern Oil Drilling

We consume more than 102 million barrels of the stuff every day [source: IEA ]. To meet our enormous demand for fossil fuels, oil companies have invested billions in developing offshore drilling operations and are constantly scouring the planet for new reserves.

Oil & Gas Cybersecurity Solution

In this article, we’ll examine how oil companies detect this buried black gold and what methods they use to extract it from the ocean and beyond.

Since the oceans cover about three-quarters of the earth’s surface, a large reserve of oil and natural gas lies underwater. Getting to these underwater drilling sites is quite difficult. After all, drilling into the ground is an enterprise in itself.

How to drill the lightless depths of the ocean and bring all the liquid, gas and solid oil back to the surface? How do you prevent the ocean from being polluted by oil spills? And how do you do all this, with a lot of specialized equipment, in the middle of the rough sea?

But where there’s a will, there’s a way. The first offshore oil well, known as “Summerland”, was drilled off the coast of California in 1896. In the next few years, oil explorers went out to sea, first on jetties and then on artificial islands.

In 1928, a Texan oilman introduced the first mobile oil rig to drill in wet areas. The structure was little more than a barge with a rig mounted on top, but it set the precedent for progress for decades to come.

Although fossil fuels have only become the driving force behind human civilization in recent centuries, oil and natural gas have been producing on the Earth’s surface for millions of years.

Most of the world’s oil is trapped under earth and rock between 500 and 25,000 feet (152 and 7,620 m). All this oil started as tiny plants and animals called plankton, which died in ancient seas between 10 and 600 million years ago. This rotting material flowed to the bottom of the sea and was covered with sand and mud over time. A kind of slow cooking process took place in this oxygen-free environment.

Millions of years of heat and pressure eventually transformed this organic matter into vast reserves of liquid, gaseous and solid petroleum, trapped beneath thick layers of rock. We call liquid oil as petroleum and gaseous oil as natural gas. Solid oil reserves usually take the form of oil shale or oil sands.

Needless to say, these fossil fuel reserves do not start boiling crude oil every time we fill up our gas tanks. Geologists study surface features and satellite maps, examine soil and rock samples, and even use an instrument called a gravimeter to detect the microscopic fluctuations in gravity that occur when oil is underground. However, all of these options aren’t particularly viable if the area you’re propagating is thousands of feet below the ocean waves.

When searching for fossil fuels in the ocean, petroleum geologists can use specialized research equipment to detect traces of natural gas in seawater. But since this method can only help find leaking reservoirs, oil companies rely heavily on two other means of locating traps.

When near the surface, some rocks affect the Earth’s normal magnetic field. Using sensitive magnetic survey equipment, a ship can traverse an area and map any magnetic anomalies that occur. These readings allow geologists to look for telltale signs of underground traps.

Surveyors can also detect potential traps by using seismic surveys. This method, known as sparking, involves sending shock waves through the water and down to the ocean floor. Sound travels at different speeds through different types of rock. If the shock wave hits a change in rock layers, it bounces off a hydrophone towed behind the research vessel.

With the help of computers, seismologists can analyze information to locate potential traps in the Earth.

The Trend In Drilling Horizontal Wells Is Longer, Faster, Cheaper

Inspection vessels use air guns and explosives to emit shock waves. Of these two methods, air weapons pose a much smaller threat to marine life, but noise pollution also poses a threat to seismically aware marine animals such as the endangered blue whale.

What happens once research teams locate oil reserves under the sea? Well, now it’s time to dial in the GPS coordinates, set up a buoy, and get a government lease to start a little exploratory drilling and see what you’ve got.

Once oil companies have identified potential oil reserves under the sea, they must obtain drilling rights. Most coasts and oceans belong to states or nations, so companies have to cede the desired areas to the respective government.

These drillships are usually used to drill exploratory wells in suspected oil reserves. Note the drill pipe segments stored on deck.

Current Drilling Techniques In Oil Extraction

You can send shockwaves to the bottom of the ocean all day, but eventually you have to do a little exploring to find out if you have potential waves on your hands.

To handle this work, oil companies send a mobile drilling unit to a location to conduct exploratory drilling. Some of these rigs are based on ships, but others have to be towed to the drilling site by other marine vessels.

An exploratory drilling rig will typically drill four temporary exploratory wells into a suspected reservoir, each taking 60 to 90 days to complete. Geologists initially drill to obtain a core sample.

The principle is the same as if you inserted a hollow cylinder into a birthday cake and then removed it. You will then be able to examine the cylinder to discover what different layers of icing and cake were present inside the cake. Will there be ice cream? It’s a way to find out without cutting off a whole piece of yourself.

Oil Rig Or Vessel? Understanding Maritime Classifications

Of course, petroleum geologists don’t expect ice cream. They look for signs of oil, which they call shows. Once the show occurs, drill stops and geologists conduct additional tests to ensure that the quality and quantity of oil is sufficient to warrant further action. If so, they drill additional wells to verify the findings.

Once geologists have established the value of oil reserves, it’s time to drill a production well and start harvesting the riches. An average well lasts 10 to 20 years before it is no longer profitable, so offshore production platforms are built with longevity in mind.

Platforms are usually fixed directly to the seabed using metal and concrete foundations or mooring cables. As you can imagine, the rig has to remain as stable as possible throughout this drilling, no matter how rough the weather.

There can be up to 80 wells on a platform, although not all of them go straight down. Directional drilling allows oil rigs to sink production wells at an angle to the ocean floor to reach deposits miles away from the drilling site. If you’ve seen the 2007 movie “There Will Be Blood,” you might recognize this as “I drink your milkshake!” Must be known by the name of. Method In the film, a frenzied, mustachioed oil tycoon claims that, through directional drilling, he has managed to extract all the oil from beneath a nearby patch of land.

A Robot Takes Over The Drilling Floor

This issue also arises in the offshore drilling industry. For example, in California, the state can apply for permission to drill new oil wells in state waters if it can demonstrate that wells in adjacent federal waters are depleting California-owned oil reserves.

Even after their wells dry up, offshore production platforms often find new life as hubs for other nearby oil platforms. Other rigs channel oil for processing and/or storage.

So you have sunk thousands of rupees to set up your oil rig. Now it’s time to get busy sipping that offshore smoothie.

You’ve set up your multi-billion dollar offshore drilling rig, and beneath you lies a wealth of untapped oil reserves. The challenge of subsea drilling is to move all the precious oil and gas from point A to point B without losing it.
