Study Notes

Oil and Gas Production and Operations

Workovers are performed to address unsatisfactory performance of a well, such as restimulating or re-perforating.
The primary goal of secondary recovery in oil production is to increase the reservoir's energy, typically through methods such as water or gas injection.
The main purpose of well abandonment is to permanently seal and isolate hydrocarbon-bearing intervals to prevent any leakage or contamination.
The world's largest ship capable of removing offshore platforms in a single lift is called Pioneering Spirit.
Surface facilities in oil and gas production are used to separate, treat, and export the fluids from the wells, including oil, gas, water, and undesirable materials.
Water de-oiling is the process of removing oil from the separated water, as the oil may exceed the permitted proportions for disposal.
Oil degassing is the process of removing the volatile components from the oil to ensure it remains in liquid form.
A typical oilfield production profile includes a peak production period followed by decline and possibly rejuvenation, and ultimately abandonment when operating costs exceed production profit.
Horizontal wells have the advantages of longer reservoir sections, higher production indices, the ability to connect laterally discontinuous features, and the ability to define the direction of flow.
Multilateral wells increase the advantages associated with horizontal wells and are more popular in Russia and the Middle East.
Key features of lower completions in well completions include liners, packers, and cemented and perforated completions.
There are two basic types of artificial lift systems: pumps and gas lift, which provide a mechanical means of pushing or pulling fluids to the surface, and lower the density of hydrocarbon to help it rise, respectively.
