Offshore Core Sampling: A Method to Discover Oil Reserves

Explore The Oil Reserves With Onshore Core Sampling

Natural gas is one of the precious assets found in the earth’s core. The oil companies have to go through several procedures to find the way to this asset. Oil extraction can be done offshore or onshore. Both the oil extraction procedures have various phases like installation of the drilling rig, drilling, core sampling, validation of sample, and assessment of the sample. Through core sampling geologists can understand the nature of rock, possibilities of discovering the oil reservoirs, permeability of the sedimentary rock, etc. Geologists in Texas extensively use the core samples for their research work and oil exploratory work. 

In this article, we will take a closer look at how onshore core sampling works.  

What Is Onshore Drilling?

As we know, the natural gas extraction procedure is categorized into two groups – Onshore and Offshore. In the name, Onshore drilling suggests the setup is installed on the seabed, but this isn’t the case. But it is installed on land, not necessarily near the coastal region. In the past few years, onshore drilling has shot up exponentially, and companies are trying to explore the onshore reserves with the latest techniques.   

Onshore drilling can be categorized into – Mobile drilling and Conventional drilling.

  1. Mobile drilling –

    the rigs are mounted on a truck to carry out the drilling, and you can easily relocate the rigs. They can explore the oil reserve up to 100,000 – 120,000 feet. Mobile drilling has further categorization viz, Jackknife and Portable Mast.

  2. Conventional drilling – 

    Unlike mobile drilling, conventional drilling rigs can’t be shifted to another location as a whole unit.


Irrespective of the methods, a huge amount of mud gets generated during drilling which is known as drilling mud. This drilling mud consists of large amounts of rock fragments, mud, chemicals used for the treatment, and water. So, an appropriate disposal system has to be planned with utmost care. The experts in the field will help you achieve your goals by designing effective gas processing equipment. It would keep the environmental issues at bay and make the extraction fruitful.

What Is The Role Of Core Sampling In The Oil Industry?

As soon as the drilling has been completed, we will collect the rock fragments produced during the drilling process. Coring services near you will avail you with the data on the nature of the rock, the inclination of the rock layers, structure, arrangement, porosity, permeability, water content, and fossil presence. To sample the core, there is an instrument called a core sampler which will take a cylindrical sample of the rock and determine its characteristics. Once comprehensive core sampling is completed, using high pressure test systems the oil pipes are checked for leaks and proceed with the extraction
