All About Drill Pipes

Drill pipes are industrial tubular used in drilling rigs to bore into the ground. These pipes are widely used in four major industries, including the oil industry, gas industry, water systems industry, and the construction industry specifically the HDD industry or the Horizontal Directional Drilling. This cylindrical tool is needed by most drilling projects. However, it is used the most in the oil and gas industry.

This drill pipe is a 31-feet proportion, known as the string, with each portion screwed together. The string also comprises of the collars and the heavy-weight cylinders. The drill bit that does the precise drilling is located at the bottom part of the string. Most drill bits are made of diamonds, providing fast and easy drilling.


Drill Pipes for Oil Drilling


In the past, drilling for oil would have drill pipes bore into the earth vertically using the drilling rigs. Today however, the direction of drilling can also be horizontal, depending on the orientation and position of the oil well. Unlike other industries, drill pipes used in the oil drilling is specifically made and designed to withstand toughest working conditions. This is primarily because it used in extreme depths and the extreme conditions beneath the earth. Oil drilling can be very deep and the string could reach for more than 30,000 feet.


Drill Pipes for Construction


Another industry that uses this superior product is the Horizontal Directional Drilling (HDD) industry, which is underground construction. In this industry, the drill pipe is used to bore major roadways and under waterways tunnels. It is the number choice of tool for construction companies especially for construction sites with unacceptable trenches. The drill hole is then used for many different utility pipelines such as water, electricity, fiber optic, oil, and gas.


HDD drilling rigs are not the same as oilfield rigs. In fact, they are the opposite because they are almost completely lying flat or in a horizontal position in the Horizontal directional drilling. The larger HDD rigs, on the other hand, have exactly the same structure as that of the oilfield rigs.


Drill Pipes for Water Wells


The drill pipes are widely used in the water well industry. This premium cylindrical product and the drilling rigs have a lighter duty in the water well drilling industry because the well is quite shallow in comparison with oil wells.


Key Points


Drill pipes can be used in many different purposes because they come in a variety of lengths. It is important to choose the highest quality drill pipe especially when you are using it in oil drilling. Make sure you buy this equipment from reputable sellers. You do not want to compromise the quality of the product over its price. Invest in a good drill pipe if you want to get the best and safest output of your project.

Sonic drilling rigs are now being used too..

Oil and Gas Offshore Drilling

The demand for oil and gas has been increasing worldwide for the past few years, and offshore drilling has played a significant role in prospering the industry. Offshore drilling involves boring for natural oil or petroleum on sea floors.


How It’s Done


The entire operation of finding natural gas or oil costs millions on drilling rigs and other equipment as well as on the workforce, including engineers, geologists, and other drilling specialists. This is a great risk for oil companies because not all exploration yield positive results.


Offshore drilling needs geologists to study the surface area. They also check the site, the satellite maps, and analyze soil samples. Geologists will use different equipment to locate oil traps. They use magnetic survey equipment to map out any magnetic variances, which points out signs of oil traps. Geologists also use shock waves for seismic surveying or sparking. Geologists will analyze the sound that is bounced back from rocks that were touched by the shock waves sent to the ocean floor.


The petroleum company will request for drilling rights from the local government where they have identified the oil trap. Exploratory drilling can only be commenced after a drilling right is granted to the company.


Oil drilling expeditions can be very expensive, so the company would drill a few wells within the site. This is for them to determine if an oil trap actually exists or not. This will also help them identify the quantity and quality of the oil. They will determine whether it is sufficient for a full-blown offshore production platform operation.


Drilling for Oil


If the quality and quantity pleases the company, they will then construct an oil platform in the area to start the harvest. Natural oil supplied, in general, can last for twenty years. Thus, the purpose and construction of the oil platform is intended and designed for long-term use. These are enormous structures anchored on the ocean floor through the use of tethering cables. Some platforms have concrete or metal foundations to ensure the stability of the platform especially during severe weather conditions.


Metal pipes or casings will be placed and are usually cemented on the drilled hole to prevent any gas leakage incidents. Drilling rigs make the entire process of accessing and extracting oil much viable. The harvested petroleum undergoes oil refinement. The purpose of oil refinement process is to separate oil, gas, water, and sediments.


For dry natural gases, you need to store and send them through pipelines for treatment. Wet natural gases, on the other hand, have different liquid particles, which is why they need to undergo filtration. When all the oil beneath the sea floor is extracted and the well dries up, the company will remove the platform and shall close the oilrig.
