Wet Crude Treatment in Brief as we mentioned in previous articles, it is required to remove water and salts from crude oil for its bad effects on oil treatment equipment and processes, and we said that wet crude has to be dehydrated and desalted in Wet Crude Treatment Plant and talked lengthily about Optimizing Wet Crude […]
PERFORMANCE ANALYSIS OF HYDRAULIC FRACTURING technique AND HIWAY FLOW-CHANNEL FRACTURING –HASSI MESSAOUD Field Case Study– MESSAOUDI Khalid (1), ABIDI SAAD Nouh (2) 1 Engineering Servicing, Technical Division, SONATRACH DP STAH, IlliZi 33000 1 Computational Mechanics Laboratory, Tlemcen university, Tlemcen13100 2 Drilling Division, SONATRACH, Hassi Messaoud, 30500 Abstract Nowadays, Hydraulic fracturing Techniques is the highest method that […]
what is Wet Crude? Raed Al-Obaidi 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. […]
Emulsion Treatment Steps Raed Al-Obaidi 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 […]
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 […]
Internal Corrosion in Oil and Gas Production Facilities Before talking about corrosion in oil and gas facilities, we have to define some of the main sections of these facilities: Gathering System and Manifolds Unit – Gather the flowlines that convey the liquid and/or gaseous hydrocarbons coming from production wells. – Send the product, by means […]
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 […]
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 […]
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 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 […]
Most of the world’s oil reservoirs now produce a mixture of oil and water. The liquids are subjected to shear forces through pumps or other lifting methods, or are sheared as they pass through pressure-reducing devices in the production line. The shear forces disperse one liquid into the other with variations in drop size and […]
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 […]
