The steps of hydraulic fracturing have been placed in order as follows:
1. The targeted shale formation is drilled to the desired depth
2. The well is completed
3. Production begins with oil and gas flowing and fracturing commencing.
4. Well abandonment which entails leaving the land as it was initially..
<h3>What is hydraulic fracturing?</h3>
Hydraulic fracturing refers to the process of injecting a well with chemicals and other materials that are needed for it to release its oil content. Hydraulic fracturing often begins with the preparation of the well to be used for the purpose.
Next is the drilling of the target area. This is followed by the completion of the well, and the beginning of production. After production is completed, the well is now abandoned or returned to the way it was when production began.
