emulsion

Emulsion Treating Part.1

      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

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

Heavy Oil Recovery

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

lubricating Oil

Lubricating Oils Testing Methods

INTRODUCTION Lubricating oil is used to reduce friction and wear between bearing metallic surfaces that are moving with respect to each other by separating the metallic surfaces with a film of the oil. Lubricating oil is distinguished from other fractions of crude oil by a high (>400°C/>750°F) boiling point In the early days of petroleum refining, […]

Three-Phase Oil–Water–Gas 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 some cases, however, when […]

Removing H2S from Oil

    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 industry, […]

Wells – Chemicals

Chemicals Used in Fracturing The identities of chemicals incorporated in fracturing fluids were probably the first thing sensationalized about fracturing. The movie “Gasland” created quite a stir with the statement that a “cocktail” of several hundred toxic chemicals were “potentially” used in fracturing. The grain of truth was that there are many chemicals in additives […]

Chemicals Used in Crude Oil Production

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 category 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

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

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 a […]

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 […]

Vertical Separator

Two-Phase Gas–Oil Separation

      At the high pressure existing at the bottom of the producing well, crude oil contains great quantities of dissolved gases. When crude oil is brought to the surface, it is at a much lower pressure. Consequently, the gases that were dissolved in it at the higher pressure tend to come out from the liquid. Some means […]
