The oil and gas industry consumes and produces water. Water is used to drill and hydraulically fracture (“frack”) wells, refine and process oil and gas, and produce electricity in some natural gas power plants. Water is also naturally present in the rocks that contain oil and gas and is extracted along with the oil and gas as “produced water”, sometimes in large quantities. The quantity and quality of water used, produced, and disposed of or re-used varies enormously depending on local geology,

SAND CONTROL MANAGEMENT When oil is produced from relatively weak reservoir rocks, small particles and sand grains are dislodged and carried along with the flow. This sand production can create erosion in flowlines and other equipment. Sand management can be considered as a key issues in field development in most of world’s oil and gas fields.

Put simply, oil sands are an unconsolidated mixture of sand, clay and/or other minerals, water, and bitumen; therefore, the extracted product must be treated before it can be used by refineries to produce usable fuels.

Erosion of material (sand production) in an oil wellbore

The sand in the oil causes erosion in the piping system and its components such as chokes and pipe bends, increasing the costs of operating the well. Excessive sand production is, therefore, undesirable and will limit oil recovery rates. A typical measure of these limits on recovery rates is the so-called “sandfree rate.”
