Whether it is a seabed or rock, drilling large holes on all types of surfaces requires high precision and planning. One small mistake can cause heavy losses to the petroleum industries and money. To prevent such damage, you have to take the necessary precautions.
Therefore, gas and oil well operators use the wireline services to get correct measurement or to send tools into the well logging.
This service use cabling technology and some tools to perform well work-over functions such as intervening, perforation, case hole logging, fluid identification, etc.
Let’s start with the different tools associated with wireline services-
Wireline Service Tools
All the wireline tools are designed to carry out some crucial operations in the wellbore. They are inserted into the bore by hanging them at the end of the wireline cable. These tools can withstand the extreme conditions of the well-bore.
Some of the commonly used tools are:
- Tool strings
- Slickline tools
- Fishing tools
- Running tools
- Blind box
- Shifting tools
- Centralizer, etc.
What Is The Purpose Of Wirelines Services?
The most significant purpose of using wireline services is to get highly précised measurements about the wellbore properties. It gives excellent results on the spot, provides electricity and data to be transferred between the surface and the equipment lowered into the well.
Wireline services assist in the following operations by blasting holes in the tubing, locating fluid levels, or bailing out the debris-
- Perforating to facilitate the circulation to the annulus.
- Plugging wells, scrapping debris.
- Locating fluid.
- Recovering the objects in the bore.
- Evaluating the downhole temperatures.
What Are The Different Wireline Services?
Some of the important services linked to the wireline services are as under-
Perforation
Perforation is the process of creating a hole in the oil well to enable a connection between a well-bore and a reservoir. It allows a smooth flow of oil and gas from the well-bore and the pay zone.
Nowadays, due to its efficient design, the cased hole well completion is widely used in the perforating process. The cased hole well service makes use of different types of logs document the data for operations. They help to solve the issues like a stuck pipe and measure the condition of the well casing.
Cased Hole logging means retrieving measurements of a well-bore through the metal casing or inserting a metal pipe during the completion process. This method is known to provide crucial information about the drilled oil well.
For example, it helps you to find out if there is something beyond the casing that has hampered the oil flow. It also provides you with the information if you want to close the well-bore.
Wireline Fishing
This process is used to pull out the stuck objects from the well-bore. The objects that accidentally fall into the bore are called ‘Fish.’ And, the tools that recover those fallen objects are called Fishing tools.
It also helps to obtain tubing, liners, or broken equipment pieces during the drilling process. Removing all the debris from the well-bore is essential to keep the fluid clean. It prevents the obstruction in the path of the fluid.
Pressure Control
Pressure control equipment is used when an operator carries out well intervention operations to maintain the optimal pressure inside the well-bore. It uses several wireline equipment’s that are manufactured with high-quality standards to stand the tough conditions.
The various types of wireline pressure control equipment are:
- Wireline Valves.
- Hydraulic Wireline Valves.
- Equalizing System, etc.
These are some of the tools and services that help to perform the tasks in a streamlined manner while carrying out the wireline services.
