Oil and Gas Production and Operations Quiz

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.
