The compact wellhead serves the same purpose as the convnetional wellhead, that is to serve as the suspension point for the casing strings in the well. The difference is that the compact assembly is just that, compact. It facilitates the suspension and setting of the casing strings over a shorter height. This saves space a … Continue reading Compact Wellhead
The casing head represents the base of the wellhead assembly, it begins the transition of the wellbore from sub-surface casing to surface/topside infrastructure. The casing head is often attached to the first casing via threaded or slip on and welded connection. The head will be critical in supporting the weight of the wellhead and production … Continue reading Casing Head & Baseplate (Pt. 1 of 2)
The process is typically divided into 2 stages, the pad and the slurry. In the first stage the slurry is injected into the well to break down the formation and thus create the pad. At this stage the fluid injection rate is greater than the rate at which the fluid can escape the formation. The … Continue reading Fracking (Pt. 2)
This is the process whereby the fissures and existing cracks within a geological formation are expanded and enlarged by the application of pressure. The process seeks to increase the permeability of fluid bearing rocks so as to increase the flow of the fluids through it. The process is employed within the oil and gas sector … Continue reading Fracking (Pt. 1)
