5 Necessary Steps For Oil Well Completion

Simple drilling a hole in the ground does not bring anything related to oil or gas reservoirs. Sometimes the drill hole is nothing more than dry well, and sometimes it gives a sign of the presence of oil under the earth. So, the operator needs special tools to check whether a hole is useful or not. The complete process of transforming a well into production unit of oil and gas is known as well 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 the productive oil well. 


Open Hole Logging:

Open hole logging is one of the most common types of logging that is done during or after the drilling of 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 is done regarding porosity and resistivity in the downhole. Porosity is a measure of the total volume of well and resistivity means the ability of a material to pass an electric current through them.

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:

To protect the excellent hole from getting collapsed and contamination of fluid in the formation, the housing is important. The casing is a hollow steel pipe that you insert in a wellbore that will protect the good 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 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 is the measure of well formations and properties of fluid after cementing the wellbore. This provides additional information to operators about well that have been completed.

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

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


Gravel Pack:

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

A proper completion requires special tools and professionals because only professionals where to dig to get for the oil well. You need to do all the downhole measurements carefully to get the accurate results. Your efforts and professionals help to dig oil well will benefit you in many ways.
