The exploration of crude oil and natural gas is a complex and risky process based on state-of-the-art technologies and materials. In this context, casings / premium casings play a crucial role. These special pipes are not only used to support boreholes, but also to ensure the safety and efficiency of the entire production operations.
Swaging the pipe ends plays a central role in preparing these pipes for further use. This process is used to optimize the dimensions of the pipe ends of casings to ensure that they meet the high precision requirements for attaching the threads.
In addition to the requirements for reliable mechanical properties of the pipes, particular attention is paid to the dimensions of the pipe ends. Here, the highest demands are placed on the roundness of the pipes in order to be able to attach the required threads with the least possible material removal and without residual staining.
Depending on the desired connection, the pipe ends are calibrated or drawn in or expanded conically or cylindrically. The swagers from GFU – Maschinenbau GmbH play a central role here. Whether for T&C (threaded & coupled), integral flush or premium connections, GFU swagers offer maximum reliability and precision.

It is generally assumed that crude oil and natural gas are formed from dead organic material such as algae and microorganisms and are converted into crude oil over millions of years under high pressure and temperatures. Even though oil is considered a finite resource, there are still general conditions for new crude oil to form. However, the time factor plays an important role here, which is why the exploration of crude oil continues to play a central role in tapping existing deposits.
The term oil exploration describes the development of oil deposits on land (onshore) or at sea (offshore). To this end, boreholes are drilled into the deposits. The drill pipes used convey the overburden to the surface. The borehole is lined with steel pipes (casing) to stabilize it. Oil exploration and gas exploration are similar.
Oil and gas exploration begins with geophysical and geological surveys to identify potential deposits. The subsurface is mapped using seismic waves and geological analysis. Once a promising area has been found, test wells are drilled to confirm the presence of crude oil or natural gas. A drilling rig is then used to reach deep enough into the ground to develop the deposit. In this way, oil and gas exploration ensures that the resources can be extracted efficiently and in the most environmentally friendly way possible.
