How Drilling Rigs Revolutionize the Oil and Gas Industry

MPD drilling, which stands for Managed Pressure Drilling, is an advanced technique used to manage the pressure of the wellbore and is widely used in oil and gas extraction. This drilling technique is an efficient technique used to overcome the drilling problems that occurred during the conventional well drilling process. To regulate the pressure of the drilling fluid during the wellbore process, MPD drilling is frequently used on drilling rigs. Drilling rigs are the only way to extract oil and gas resources from the earth’s surface. In this blog post, we will mention some of the rigs drilled by the oil and gas industry.

There is a fluid monitoring system equipped to check whether the drilling process is going right or not and whether the pressure of the drilling fluid is okay. It is an intelligent technique that ensures that the process is going smoothly and accurately. Drilling mud can choke or misbalance the pressure of the drilling rig, but thanks to a fluid monitoring system, it helps to check all the activities of drilling mud or fluid during the well bore process.

Types of drilling rigs for oil and gas extraction:

There are many types of drilling rigs that totally depend on the requirements of the site. When it comes to the oil and gas sector, drilling rigs are the only means of extracting these natural resources. Now, let’s explore some types of drilling rigs used to extract oil and gas resources:

1) Land drilling rigs:

a. Rotary Drilling Rig: The most prevalent kind of drilling rig used onshore is a rotary one. To access the oil or gas reservoirs, they are outfitted with rotating drill bits that cut through the rock formations. To rotate the drill string and exert downward force during drilling, these rigs use rotary tables or top drive systems, and MPD drilling is there to balance the pressure within the wellbore.

b. Cable Tool Rig: A tool known as a cable tool rig, also known as a percussion rig, connects a strong drill bit to a cable. The drill bit is raised and lowered repeatedly to fracture rock formations. Although it is less common today, this kind of rig was once employed to drill shallow wells.

c. Workover Rig: The upkeep and repair of already-existing wells is done with the aid of workover rigs, and a fluid monitoring system is used to ensure that the pressure of drilling fluid is as per the need or not. They are typically more compact and portable than drilling rigs and are made for well intervention operations like removing and replacing machinery, stimulating wells, and performing corrective work.

2) Offshore drilling rigs:

a. Semi-submersible Rig: A semi-submersible rig is a floating structure with large pontoons or columns that partially submerge below the water surface. In order to provide stability in choppy sea conditions, these rigs have ballast systems that enable them to be submerged entirely or partially. Deepwater drilling frequently uses semi-submersibles because they can function in challenging conditions.

b. Platform Rig: Platform rigs are employed on fixed platforms or production facilities that are anchored to the seafloor. These structures usually operate in shallow water and offer a stable surface for drilling and production operations. IPC systems are equipped to keep an eye on the process of drilling and check the process of well drilling throughout. Platform rigs can be standalone units or have a modular design that makes assembling and disassembling them simple.

c. Tender Rig: A drilling rig that is attached to a stationary platform or vessel is known as a tender rig. It cannot move on its own; instead, it must be towed or transported to the drilling site. Drilling in shallow to medium water depths is done with the aid of tender rigs, which are dependent on the platform or vessel for support and habitation.

3) Onshore drilling rigs:

a. Drillship: A drillship is a maritime vessel specifically designed and equipped for offshore drilling operations, including MPD drilling. It typically has a derrick (a tall framework) that supports the drilling equipment, including MPD systems. Drillships are capable of drilling in a wide range of water depths, from shallow to ultra-deep. They are often used in offshore exploration and production activities, utilizing MPD techniques and fluid monitoring systems for enhanced well control and efficiency.

b. Jack-up Rig: A jack-up rig is a particular kind of mobile offshore drilling unit (MODU) that is utilized for drilling in shallow to medium water depths. It consists of a floating hull with stabilizing legs that can be lowered to the ocean floor. The rig is raised above the water line to create a stable platform for drilling operations after the legs are firmly planted on the sea bed.
