Drilling operation: seven essential steps of extracting oil and natural gas

fluid monitoring system

Technology plays a significant role in almost every industry, but when it comes to the oil and gas sector, technology has become more advanced to support well-completion solutions. These advanced technologies improve the efficiency of wellbore drilling operations, resulting in the ease of extracting natural resources from the earth. Fluid monitoring systems are also part of the advanced technology used in wellbore operations that will increase the efficiency of drilling operations. 

In addition, MPD drilling, which stands for Managed Pressure Drilling, is also an advanced technique that supports drilling operations in different aspects. This Managed Pressure Drilling technique keeps a close eye on the whole procedure of well drilling. This technique also helps to smooth the process and ensure that the drilling operation will go without any complications. In this blog post, we will delve into the steps involved in the procedure for oil and gas drilling operations. 

What are the most advanced techniques and products adopted by the oil and gas industry?

The oil and gas industry has adopted a number of cutting-edge techniques and equipment to increase productivity, cut costs, and shortens project timelines. Let’s name some of them:


  • Various dissolvable frac plugs
  • IPC system
  • Drilling fluid
  • Rheology sensors
  • Fluid monitoring system
  • Wellbore strengthening material, and many more

Procedure for drilling operations:

Now, we are going to delve into the steps involved in oil and gas extraction:

1)    Preparing the Rig Site:

A company must first construct the infrastructure needed to support safe, responsible, and legal drilling before beginning operations. Along with pads and access roads, these facilities should also have access to water and electricity. The drilling process can start after the site has been planned and surveyed, along with the necessary infrastructure, safety measures, and prior permissions. 

2)    Drilling:

Now is the time to start drilling in order to extract oil from the earth's surface. Drilling is the most crucial step in well-completion procedures and extracting natural resources from the earth. Fluid monitoring systems play an important role in the drilling phase in order to ensure that the drilling operation is going smoothly. In the drilling operation, you have to drill the earth’s surface until you reach your target point, where you plan to extract oil. 

3)    Cementing and Testing:

The drill pipe is removed when the desired distance has been reached, and the steel pipe is then lowered to the ground. This "well casing" is fixed in place with cement. Before any natural gas or oil production can start, extensive tests are run to make sure the pipe is impermeable. 

4)    Well completion:

The next step is to establish a connection between the finished casing and the rock layer containing the oil and gas. In order to accomplish this, a specialized "perforating gun" is lowered to the rock layer and fired to pierce the cement layer by making holes in the target rock and between the casing pipe. Even though they are only a few inches long, these perforating holes do not produce any noticeable surface activity. After it is finished, the perforating gun is taken out, and the subsequent phase, hydraulic fracturing, can start.

5)    Fracking:

The next step in the drilling process for oil and natural gas is hydraulic fracturing, also referred to as "fracking." The process starts with the injection of high-pressure stimulation fluid into deep underground reservoir formations, which is a mixture of sand and water (with some chemical additives) that contains about 90% water. To lubricate and stop the growth of bacteria, chemicals are added to the fracturing fluid, and the MPD drilling technique is there to keep a close eye on the procedure. They enhance the effectiveness and performance of hydraulic fracturing and are non-hazardous, low concentration, and essential. 

6)    Production and fracking fluid recycling:

Oil can start to be produced from the well after the hydraulic fracturing procedure is complete. In addition to recovering the fracturing fluid, the well bore produces oil and natural gas. About 25-75% of the fracturing fluid used during a well's initial production is recovered and either recycled in subsequent fracturing operations or disposed of in accordance with environmental regulations. 

7)    Well abandonment and land restoration:

The land used as the drill site must be restored to its initial condition before the operation begins after all of the viable oil and natural gas have been extracted. To do this, the well is filled with cement, and the entire drill pipe is severed about 6 feet below the surface. After the surface hole has been filled, all surface equipment will be taken out and any well pads will be filled. As a result, there is little to no sign that a well site ever existed, and the land returns to its original state.

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, i...
