Oil Well Completion
Simply drilling a hole in the ground does not bring anything related to oil or gas reservoirs. Sometimes, the drill hole is nothing more than a dry well, and sometimes, it shows the presence of oil under the earth. So, the operator needs special tools to check whether a hole is sound. The complete process of transforming a well into a a production unit of oil and gas is known as thriving completion.
  • Do you want to start the oil industry and need more information on proper completion?
Here is the list of steps that you need to follow to convert a drilled hole into a productive oil well. 


Open Hole Logging:

Open-hole logging is one of the most common types of logging done during or after the drilling of a well. This kind of wireline logging helps in getting an accurate measurement of the first hole before cementing it. Many logging tools will assist in collecting the data from the borehole.

The measurements taken by logging tools are done regarding porosity and resistivity in the downhole. Porosity is a measure of the total volume of a well; resistivity means a material's ability to pass an electric current through it.

Open-hole logging gives valuable information about the type of soil, the presence of rocks, fluid type, and more under the ground.


Casing Of Hole:

The housing is essential to protect the excellent hole from collapsing and fluid contamination in the formation. The casing is a hollow steel pipe you insert in a wellbore to safeguard the superb stream from outside incumbents like sand and water.

Cementing Of Downhole:

This is the next step after casing that you need to do for a quality oil well. For fastening, make a slurry of cement and water, then displace it down in the casing or tubing of the well. This will provide support to the housing of the wellbore. Further, it will save the casing from corrosion and shock loads of fluid.

Cased Hole Logging:

Cased hole logging services are the measure of good formations and properties of fluid after cementing the wellbore. This provides additional information to operators about wells that have been completed.

Further, this includes perforation of the casing and cementing wall of the wellbore to allow hydrocarbons to enter the excellent stream. You can do perforation by firing bullets from the perforation gun or by discharging jets into the casing.

There are tools like a multi-finger caliper, pulsed neutron decayed tool, electromagnetic thickness, and resistivity log that you can drop down with the help of a wireline to measure the physical and chemical properties of fluid and casing.


Gravel Pack:

Sometimes, the well needs a filtration system to keep the fresh fluid free from sand. Along with casing, gravel packing prevents the sand from entering the excellent stream. With proper design and installation, the gravel packing ensures the long-term performance of the oil well. It requires a slurry of appropriately sized pieces of coarse sand or gravel to put into the well between the slotted area of the casing and the sides of the wellbore.

Proper completion requires special tools and professionals because only professionals know how to dig to get to the oil well. You must do all the downhole measurements carefully to get the accurate results. Your efforts and professional help to dig oil well will benefit you in many ways.
