What Types of Drill Rigs for Sale Are Available Today?

There are many different kinds of drill rigs for sale in the country. Drilling rigs are basically used as protective structures, and their main purpose is to house important drilling equipment and tools including the derrick, cables, and drill bits. They are essential materials used in the extraction of raw petroleum from underneath the surface of the earth. 

If you will go down to the basics, offshore oil rigs come in several different types. They are designed to work in various locations, different environments, and certain kinds of wells. 

  • As a highly mobile drilling structure that comes with bottom supports, Jackups are equipped with open-truss or columnar legs. The purpose of this is to provide structural support to the hull area or main deck. 
  • Unlike Jackups, platforms are not mobile and thus cannot be moved. One typical feature for platforms is that they are made from cement or steel, and they are highly useful in drilling for new development wells. 
  • The floaters, or sometimes referred to as the semisubmersibles can stay afloat using giant pontoons. Sometimes they are made from hollow columns, instead. They can submerge to a desirable depth when filled with water. A floater type of drill rig is highly reliable in rough seas and most of the time they are being used to drill new wells.  

There are several primary systems from which the vast majority of drilling rigs rely on to get the job done: 

  • A hoisting system. Most of the time, they’d refer to this as drawworks or derrick. 
  • A drive group consisting of chains, motors, and compounds. 
  • A circulating system of kelly, return lines, drill string, pumps, and pits. 
  • Well, control equipment. 

There are various reasons why we need to drill a well. If our purpose for drilling a new well is to find a new reservoir, we call it an exploratory well. We also have development wells, which is most applicable in proven oil fields. Their main purpose in the area is to maximize the production of oil coming from that field.  

The most common and widely used drilling technique we have nowadays is the rotary type of drilling. The working principle behind this method is to force the drill bit down towards the earth, whereby in the process it will make a hole or a wellbore. A drill stem is attached and will rotate the drill bit, and is also providing a passageway where the drilling fluid is circulated. Drilling fluid is mud.  

Below are some important information concerning wells and how they get drilled. So much so that it is not always a “ straight down” action.  

If you will hear of a well that will be drilled the conventional way, it only means to say that the well is going to be drilled vertically, straight down to the oil itself.  

When it comes to traditional drilling, one can’t expect that the process will always yield the best results. Usually, the driller tends to go down vertically, and then go for a horizontal sharp turn. 

For this to work, the use of special drill bits is necessary.  

With the kind of technology and equipment we have these days, together with the available drill rigs for sale in the country, all these together help to bring us a step closer to a very precise directional drilling.  

Sonic Drilling Pointers for Environmental and Geotechnical Drilling Works

In the last 20 years, sonic drilling has displayed impressive growth in terms of acceptance and popularity. Two primary key elements are paramount to this growth. The first one has something to do with the development of seasoned and skilled drillers who will be delegated to perform this job and second to this are the latest advances and developments in the sonic drilling technology.  

Provided that a sonic drilling operator or staff is highly skilled, he is not going to have a hard time achieving high production rates. He is also likely to obtain exceptionally good quality samples from an array of subsurface conditions. The sonic drill rigs are capable of reaching greater depths while at the same time trying to get near 100% in sitecore samples.

Know When You Should Make Use of Sonic Drill Rig

Having a deeper understanding of where and when to take advantage of the sonic drilling technique over other available but traditional methods of drilling is paramount to delivering a cost-effective outcome to your customer. 

We have below 2 practical reasons why you should pick this drilling technology instead, sonic drill, over many other methods. 

  1. Drilling projects requiring continuous site samples that need to be collected — this contrary to reverse circulation drilling. The chips in this method of drilling are collected instead. 
  2. In situations where you need to veer away from air and fluid while the drilling process is ongoing. Sonic drilling does not require both air or fluid. This explains the reason why it is the method of choice for geo-construction, geotechnical and environmental applications. Significant cost savings are likely to materialize in the sonic type of drilling. 

These are the kind of drilling projects that will necessitate you to shell out a good amount of money. You also need to exert some effort in your work here so that you can dispose of your drill cuttings or investigation derived waste or IDW. Drilling dry minimizes the anticipated amount of liquid against the rotary type of drilling (drill water/mud). 

For those drilling projects with observable unconsolidated formations of the ground are encountered, sonic type of drilling is the method of choice to use here. It is very good at handling pebbles, boulders and everything in between while giving the borehole that needed an amount of integrity by virtue of continuous casing process.  

Maintain Your Sonic Rig

It is very important to see to it that your tooling and sonic rig are always in tip-top shape or optimal running condition. It is paramount to the long term productive life of sonic drilling. 

To help you identify and fix issues right away even before downtime for your equipment occurs, preventive maintenance should be observed and followed. Therefore, see to it that you have your sonic rig checked and do it regularly.  

Keep Safety in Check

In any drill site facility, the safety of everyone working there is very important. Promote and inculcate in the minds of your team culture of safety. Encourage your drill crews to always think first, a hundredfold, before taking action. By this measure, every single one of them will be trained to focus their mind and energy to the task they have at hand. It should always be one task at a time.
