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 […]
why crude oil is stabilized? Once degassed and dehydrated–desalted, crude oil is pumped to gathering facilities to be stored in storage tanks. However, if there are any dissolved gases that belong to the light or the intermediate hydrocarbon groups it will be necessary to remove these gases along with hydrogen sulfide (if present in the crude) before oil […]
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 […]
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 […]
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 […]
by: Mohammed Altahir Eliebied Petroleum Engineer Job Description & Career Opportunities A petroleum engineer is a subset of the engineering career, focused upon the exploration for and extraction of hydrocarbons (crude oil or natural gas). Petroleum engineers often work closely with geologists to determine where accessible reservoirs of hydrocarbons are located, as well as the […]
Bernoulli Equation It is customary to express the energy contained in a fluid in terms of the potential energy contained in an equivalent height or “head” of a column of the fluid. Using this convention, Bernoulli’s theorem breaks down the total energy at a point in terms of: 1. The head due to its […]
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, […]
Surface Production Equipment – Well head – X-mass tree Subsurface Production Equipment – Tubing – Packer – Bridge Plug – Safety Valve Production Wellheads The surface termination of a wellbore that incorporates facilities for installing casing hangers during the well construction phase. The wellhead also incorporates a means of hanging the production tubing […]
Removing water from crude oil often requires additional processing beyond gravitational separation. In selecting a treating system, several factors should be considered to determine the most desirable methods of treating the crude oil to contract requirements. Some of these factors are: Tightness of the emulsion. Specific gravity of the oil and produced water. Corrosiveness of […]
Crude Oil Price First of all we have to understand the Classification of Petroleum Products. The petroleum products that may be subject to evaluation can be grouped as: crude oil – natural gas – associated products Crude oil is a liquid composite of many hydrocarbon compounds that, depending on the composition, has differing properties such […]
In addition to the requirement that source rock exists for the generation of hydrocarbons, and that reservoir rock exists for the storage and production of the generated hydrocarbons, traps must also exist to trap, or seal, the hydrocarbon in place forming a hydrocarbon reservoir. The fluids of the subsurface migrate according to density. As previously […]
