The production tree represents the top of the topside production equipment. The tree is typically comprised of a series of valves, junctions and tubing so as to be able to control both the pressure and flow into and out of the well and subsequently the reservoir. Typically the tree attaches to the top of the … Continue reading Production Tree
Wettability The tendency of one fluid to spread on or adhere to a solid surface in the presence of a second fluid. If two immiscible fluids/phases are placed in contact with each other and a solid phase one of the two is more attracted to the solid phase. The more strongly attracted is the wetting … Continue reading IOR Concepts
Definition This is the process of enhancing oil production by the injection of a fluid into the reservoir, specifically EOR is done using engineered fluids that utilize methods beyond natural energy and augmented natural energy. EOR is the result of the injection of gases or liquid chemicals and/or the use of thermal energy. The injected … Continue reading IOR Definitions
Casing hanger – this is installed to support the individual casing strings in the well. This is the landing base or casing head. This is usually welded or screwed to the top of the surface casing string. The surface casing string serves as a foundation pile for the well. This transfers the hanging load to … Continue reading Wellbore Tubulars
