Two-Phase Gas–Oil Separation

Vertical Separator

      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 …

Oil Refinery Processes

refinery

  Process Objective: To distill and separate valuable distillates (naphtha, kerosene,diesel) and atmospheric gas oil (AGO) from the crude feedstock. Primary Process Technique: Complex distillation Process steps: –Preheat the crude oil feed utilizing recovered heat from the product streams –Desalt and dehydrate the crude using electrostatic enhanced liquid/liquid separation (Desalter) –Heat the crude to the …

Detection of Oil Spills

oil spill

 Oil Spills Special instruments are sometimes required to detect an oil spill, especially if the slick is very thin or not clearly visible. For example, if a spill occurs at night, in ice, or among weeds, the oil slick must be detected and tracked using instruments onboard aircraft, satellites, or spacecraft. This technology is known as remote sensing. …

Oil Well Planning

oilfield

How to plan for an Oil Well? Drilling optimization requires detailed engineering in all aspects of oil well planning, drilling implementation, and post-run evaluation Effective well planning optimizes the boundaries, concstraints, learning, nonproductive time, and limits and uses new technologies as well as tried and true methods. Use of decision support packages, which document the reasoning behind the decision-making, is …

what is Naphtha

naphtha

what is Naphtha Naphtha is a liquid petroleum product that boils from about 30°C (86°F) to approximately 200°C (392°F), although there are different grades of naphtha within this extensive boiling range that have different boiling ranges . The term petroleum solvent is often used synonymously with naphtha. On a chemical basis, naphtha is difficult to define precisely because it can contain …

Acidizing Different Formations

ATTACHMENT DETAILS acidizing

what is Acidizing Much of the worlds oil and gas comes from limestone (CaCO3) and dolomite (CaMg(CO3)2) formations, either in their relatively pure form or in the form of carbonate or siliceous sands cemented together with calcareous materials (CaCO3). Dolomites are similar to limestones with the exception that they generally react more slowly with hydrochloric acid. The primary …

Oilfield Paraffin and Asphaltene

paraffin oil

Paraffin control products prevent crude oil precipitation of paraffin wax deposits in production risers, subsea tie-backs, or any other production tubular or transportation pipeline. Paraffin – Asphaltenes and Inhibitors Some formulation products are wax crystal modifiers that prevent paraffin formation by interfering with the bonding of aliphatic wax molecules. Composed of branched chain polymers, these …

Crude Oil Components

crude oil

      On average, crude oil are made of the following elements or compounds: Carbon – 84% Hydrogen – 14% Sulfur – 1 to 3% (hydrogen sulfide, sulfides, disulfides, elemental sulfur) Nitrogen – less than 1% (basic compounds with amine groups) Oxygen – less than 1% (found in organic compounds such as carbon dioxide, …
