Wet Crude Oil Treatment Plant

what is Wet Crude? in the beginning of the production from any reservoir the crude oil contains no water and salt; with time it begins to produce large amounts of water and salt, although the density difference guarantee that water stays bellow crude oil in the reservoir, but sometimes water content will with time. wet crude […]

Optimizing Wet Crude Treatment

Emulsion Treatment Steps In general, the treatment of water emulsions in crude oil consists of 3 stages: emulsion breaking: includes breaking the film that surrounds the water droplet, by the aid of heat and demulsifier. water droplet coalescence: water droplets combine with each other after breaking the emulsion and being free forming big droplets, coalescence […]

foam in oil gas separators

foam in crude oil foam is a small bubbles of gas surrounded with a thin film of oil, this phenomena reduces the separation efficiency, foam exists in the gas oil interface when separator pressure decreases, or because of the surface tension, viscosity, and some impurities, because of that, small droplets are generated, these droplets are […]

Liquid Carry-over and Gas-blowby in oil gas separators

      when we talk about oil gas separators in the modern designs of GOPS, the designers took into consideration all operation problems, by adding high sensitivity control valves, and accurate pressure and level indicators which decreased these problems to the minimum, most operation problems now are occurring because of bad operation, human mistakes, or […]

H2S in Oil Industry

    Introduction This article impacts on human health caused by exposure to hydrogen sulfide (H2S) associated with crude oil and natural gas development. It begins with a brief background on hydrogen sulfide, its presence in oil and natural gas, and possible emission sources from various oil and gas operations. epidemiology, and industrial health publications, as well as […]

Sand Control

  Consequences of sand production: • Wellbore fill. • Equipment problems due to sand fill. • Sand erosion of downhole and surface equipment. • Sand accumulation on surface and Sand Disposal. • Production Loss. • Casing / Liner Collapse. Forces Aiding in Resisting Sand Production: • Intergranular frictional forces and bonding (cementing) help resist grain movement • Capillary […]

Emulsion Treating Part.2

Emulsion-Treating Methods An emulsion-treating unit or system will use one or more of the methods to aid in destabilizing, coalescence, and/or gravity separation. Each of these treating methods is discussed separately below. Heating. Using heat to treat crude-oil emulsions has four basic benefits: Heat reduces the viscosity of the oil, which allows the water droplets to collide […]

Crude Oil Treatment

Crude Oil Treatment   Electrostatic & Mechanical Treaters Introduction After primary oil/water separation, there is often a small amount  of unwanted salts in residual water in the crude oil that needs to be reduced to a concentration around 5-10 PTB (Pounds per Thousand Barrels) salt. This salt needs to be removed so that the crude oil […]

Heavy Oil Recovery

    American Petroleum Institute API classifies crude oil into different types as follows: 1. Light Crude Oil : its API is greater than 31.1° 2. Medium Crude Oil: its API is between 22.3° and 30.2°. 3. Heavy Crude Oil: its API is between 22.3° and 10°. heavy crude oil has a high viscosity, high […]

what Heavy Oil, tar and bitumen mean

        Heavy oil is a type of petroleum that is different from conventional  petroleum insofar as they are much more difficult to recover from the subsurface reservoir. Heavy oil, particularly heavy oil formed by biodegradation of organic deposits, are found in shallow reservoirs, formed by unconsolidated sands. This characteristic, which brings about difficulties during well […]
