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 …

what Heavy Oil, tar and bitumen mean

heavy oil

        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 …

Three-Phase Oil–Water–Gas Separators

Separator

3-Phase Oil-Gas-Water Separators in general, to the separation of any gas–liquid system such as gas–oil, gas–water, and gas–condensate systems. In almost all production operations, however, the produced fluid stream consists of three phases: oil, water, and gas. Generally, water produced with the oil exists partly as free water and partly as water-in-oil emulsion. in both cases it should be …

Reservoir Simulation Data Management

Reservoir Simulation Data Management Eng.Ali Yahya Jirjees Salman Introduction Data from a wide variety of sources are required for reservoir simulation. Simulation itself produces large quantities of data. Yet, good data management practices for reservoir simulation data are typically neither well-understood nor widely investigated. Reservoir simulation is inherently a data-intensive process. It starts with geological …

Removing H2S from Oil

H2S

    1. INTRODUCTION Sulfur compounds exist in various light oils made from petroleum. Such as mercaptan, hydrogen sulfide, which cause foul odors and deteriorate the finished products. In addition, due to their acidity, they are corrosive to metals, which is harmful for storage and usage of oil products. Therefore, it is necessary to remove them. In the refining …

Chemicals Used in Crude Oil Production

Chemicals

Petroleum “A complex combination of hydrocarbons. It consists predominantly of aliphatic, alicyclic and aromatic hydrocarbons. It may also contain small amounts of nitrogen, oxygen and sulfur compounds. This article encompasses light, medium, and heavy petroleums, as well as the oils extracted from tar sands. Hydrocarbonaceous materials requiring major chemical changes for their recovery or conversion to petroleum refinery feedstocks …

Offshore Petroleum Platforms

offshore platform

what are offshore platforms? Offshore structures are used worldwide for a variety of functions and in a variety of water depths, and environments. Since right selection of equipment, types of platforms and method of drilling and also right planning, design, fabrication, transportation, installation and commissioning of petroleum platforms, considering the water depth and environment conditions are very important, this …

Gas–Oil Separators part. 2

Separator

  Inlet Diverters Inlet diverters are used to cause the initial bulk separation of liquid and gas. The most common type is the baffle plate diverter, which could be in the shape of a flat plate, a spherical dish, or a cone. Another type, is the centrifugal diverter; it is more efficient but more expensive. The diverter provides …

Commercial Types of Gas–Oil Separator Based on the configuration, the most common types of separator are horizontal, vertical, and spherical, Large horizontal gas–oil separators are used almost exclusively in processing well fluids in the Middle East, where the gas–oil ratio of the producing fields is high. Multistage GOSPs normally consists of three or more separators. The following is a …
