How Do Drill Rig Companies Work? Prepare Land for an Oil Rig?

Spread the love

Following the selection of an oil rig location, the next course of action that scientists working for drill rig companies will take is to survey the field. They will decide what the probable limits are, and, if possible, carry out an investigation to identify whatever possible impact that a planned drilling work will bring on the environment. 

The oil company may be asked to sign land title lease agreements and, and the off-shore legal authority sites could be decided. The land will receive the necessary preparation after all of these concerns have been properly addressed. This may be seen as a time-consuming measure, yet it can’t be denied that it is essentially important. 

The crew can work to clear and level the land. On the side, if at all possible, they can build access roads. The staff of drill rig companies can also dig a well in the absence of a natural water supply that is near their project site since water is paramount to the success of any drilling project.

In order to get the field ready and prepared, even more, they can work to hollow out the reserve pit. This can be used as a disposal pit for drilling mud and rocks. Plastic can be taken advantage of to line the pit. 

If the project site is ecologically or environmentally sensitive, such as a marshland or wilderness, the mud and rock cuttings can be tucked away for disposal elsewhere rather than being dumped in a landfill.

As soon as everything is ready and prepared, the drilling crew can commence drilling several holes in the property. 

oil rigThe first hole is going to be a “cellar” or a rectangular pit, or something that will surround the actual drilling hole location. This will serve as the workspace for the drill crew and staff. It can also serve as a temporary station for drilling equipment and accessories. As for the main hole, it will be divided into 2 parts.

The shallow and larger section can be drilled using a small truck rather than the main rig. Eventually, this will be lined up with a conductor pipe. 

The main part of the hole, which is also deeper, is then drilled. Additional holes are dug off to the side, which can function as temporary equipment storage. Finally, depending on the location of the drill site, the rig equipment is brought in by truck. Sometimes, the help of a barge or a helicopter is used for this purpose.

Abandonment

An oil well does not “die”. It instead reaches what industry experts call its “economic limit.” This is the point at which the oil or gas it produces no longer serves the operational costs. 

When this time comes, the tubing can be removed and the cement is poured immediately. This measure will help ensure that the hydrocarbon reservoirs will be separate from the water. In addition, they are also cut off from the surface.

As for the pump head, it will be excavated for eventual removal. A cap must be welded on it for added security, and the whetstone will require a replacement.

What are the Different Types of Drilling Rigs for Sale in Australia?

If you have good plans for acquiring a drilling rig anytime soon, it would be best that you familiarize yourself first with the types of drilling rigs for sale in Australia. 

This way you’d know what to look for first and get good value for your money, as opposed to leaving things out on luck. 

drill techniques

So, without further ado, what is a drilling rig used for? 

Drilling rigs are solid structures and they are used to house equipment for a drilling project such as cables, pipes, derricks and drill bits. Every one of them plays a crucial role in extracting important commodities from underneath the ground such as petroleum. 

There are two categories for drill rigs, they are either offshore or land. Offshore drilling, as itself suggests, is done at the very bottom of the ocean floor, whereas land-based drilling works are done on land.  

Drilling rigs are not for the exclusive of the petroleum exploration industry, there are many other applications for it, too. For instance, they play a major role in the construction industry and are used primarily in building foundation construction for bridges, roadbeds, and airport constructions. Such construction projects require no less than extremely strong foundations. 

They are also used in the mining industry and water drilling projects.  Offshore oil rigs are designed in such a way that they will work in many different locations and differing environments.  

  • Movable drilling structures that come with bottom supports, these are what we refer to as the jackups. They have columnar or open-truss legs which are intending to provide the structural support needed by the main deck area or hull. 
  • Unlike jackups, you can’t move/relocate platforms since by virtue of their design they are not supposed to be mobile. It is typical for platform drill rig systems to be made out of cement or steel.  And when it comes to developing new water wells, this drill rig system is most preferred to use by most contractors.  
  • Then we also have floaters or semisubmersible drilling units.  With the use of hollow columns or giant pontoons, these drill systems stay afloat. So much so that when you fill its columns or pontoons with water, they will be submerging to the desired depth. This type of drilling rigs for sale in Australia are most reliable to use when working on rough seas, but they are also ideal for use in drilling new wells.

The majority of rig setups we have in the country rely on several systems to help get the job done right the first time: 

  1. The hoisting system, we refer to this as drawworks or derricks. 
  2. The drive group, this is consisting of chains, motors, and compounds. 
  3. The system of the drill string, a system of pumps, kelly, pits, and return lines. 
  4. The well control equipment. 

There are various reasons why we drill wells. If you are involved in a drilling project to identify new reservoirs, we will term this as an exploratory well. As for the development wells, they are all about working on already proven oil fields and maximizing the amount of oil being produced from that area.  

When you hear something about a drilling project done the traditional way, it only signifies that the well will be drilled down, straight down vertically directed to the underground deposit of oil.

It is important to be aware that the conventional way of drilling will not always yield your expected best results. Most of the time, drilling contractors would work their way down vertically to the ground, and then they would make a sharp, horizontal turn. Such a maneuver would necessitate the use of specialized types of drill bits.

How Sonic Rigs Work?

Spread the love

Sonic rigs are known to employ an advanced form of drilling. 

It makes use of resonant, high-frequency energy created inside the sonic head, increasing its efficiency in creating a borehole. By this measure, the casing or core barrel will be able to seamlessly advance into the subsurface formations. 

drilling project

In the course of a drilling process, the resonant energy will be relayed to the drill string and directed to the bit face. This occurs at various sonic frequencies, and alongside that the rotating drill string distributes the energy evenly, impacting the bit face in the process.  

Most of the time, sonic drills are more associated with a rotary vibratory drill. It can efficiently handle high drill speeds and can accomplish tasks like continuous coring. Such a kind of drilling task is almost impossible to carry out if you are just going to use some other drilling tool. 

At first, glance, if you don’t know anything about it, you’d think that the sonic drill looks like any traditional mud rotary drill rig. The primary distinction it comes with can be found in the drill head. It is slightly bigger as opposed to a standard rotary head. The drill head usually houses the mechanism needed to sustain rotary motion. It also comes with an oscillator that induces high-frequency force that will be superimposed on the drill string.

As for the drill bit, it will vibrate physically in an up and down fashion, aside from being rotated and pushed down.  These three forces combined make drilling proceed rapidly with almost every kind of available geological formations, including the majority of rock types. 

In overburden cases, the vibratory action will induce the soil particles around it to somehow soften and fluidize. When this happens, there is going to be a seeming effortless penetration. The drill bit in rock is likely going to induce rock face fractures. If this happens, the production of rock dust is likely to occur and will also significantly help in facilitating the drill bit to advance.

In many instances, you can accomplish rock coring and drilling without using any kind of drilling fluid whatsoever. If you are working on a qualified environmental drilling project, it is one of the most important requirements you will need to keep in mind. Drill mud, compressed air, and plain water can be taken advantage of to take away the cuttings and further enhance the speed of the drilling operation, all depending upon which the drilling machine is originally intended for.  

The oscillator will be driven by a hydraulic motor. Besides, balance weights are also used to create a high sinusoidal force which is eventually transmitted to the drill bit.  And to restrict the alternating forces to the drill string, an air spring can be incorporated also. The frequency can vary in this regard so that it can become suitable for operating conditions. Generally, the frequency will range between 50 to 160 Hertz or cycles per second. 

For comparison purposes, in many countries today, an ordinary or average household would normally have 60 Hertz. A frequency range of this magnitude is falling within the lower range of sound vibration, which the human ear is capable of detecting and hearing. Hence, this type of rotary-vibratory drilling equipment earned the moniker sonic rig drilling.
