Water Disposal and Injection System

Offshore oil and gas is found beneath the seabed trapped within the rocks in deep underground accumulations called reservoirs. In most reservoirs, oil and gas collects above large volumes of water called formation water. Sometimes seawater is also pumped into the reservoir to maintain pressure and help the oil and gas to flow from the reservoir to a production platform or facility. Water treatment systems and injection pumps have been installed on the processing decks of offshore platforms to send filtered and sterilized seawater into the reservoirs.

Managing water quality for oil and gas production and processing is a complicated industry issue. The preferred source of injection water in an offshore environment is seawater. Drilling a new well is very expensive; therefore the water for injection has to be of a very high quality to avoid plugging and scaling of the injection equipment. Souring can occur when water containing oxygen and bacteria is injected which reduces the produced hydrocarbons' value.

This course is designed to provide participants with an overview on the different water treatment methods, for water injection systems either by produced water or seawater as found in today’s oil and gas industry.

On day 2, participants will obtain an overview process description of injection water treatment. The participants will then gain comprehensive knowledge of the purpose, function, configuration and application of solids removal equipment.

Day 3 Water Disposal and Injection Systems Process Example

  • Process Description
  • Mechanical Equipment
  • Process Control
  • Process Safety System
  • HSE Considerations

On day 3, the participants will gain comprehensive knowledge of the safe and efficient operation of a water disposal and injection system using an actual example of a world-scale crude oil separation and treatment facility. This presentation will include the review and study of actual process flow diagrams (PFD) and process and instrumentation drawings (P&ID).

This course is mainly targeted to process technicians, process technologists and maintenance personnel. The course can also be applicable to employees working with equipment and materials purchasing, equipment procurement, job planning as well as immediate supervisors to the working technicians.
