تقنیات الرفع الإصطناعي للنفط Artificial Lift Techniques for Oil عبد الوهاب الشیخ قادر – خبیر المقدمة یستمر الإنتاج من الآبار المحفورة في الحقول النفطیة ذات القوة الدافعة الطبیعیة العالیة طالما یبقى الضغط المكمني بمستویات تفوق الضغط المسلَّط على نقطة دخول الموائع من المكمن إلى البئر. و لكن ذلك لن یدوم بسبب الهبوط الإعتیادي للضغط نتیجة سحب النفط من […]
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 […]
Acid Types Although many acid compounds are available to the oil industry, only the following types have been proven economically effective in oil well stimulation: Inorganic Acids (Strong). · Hydrochloric Acid (HCl). · Hydrofluoric Acid (HCl:HF). Other inorganic acids include Sulphamic, Sulphuric and Nitric acids. Organic Acids (Weak). · Acetic Acid and Glacial Acetic […]
what is Scale? Scale is normally a buildup of salts of calcium, barium or strontium as calcium carbonate, barium sulfate and strontium sulfate. Carbonate scale is caused by the presence of calcium and bicarbonate ions in the formation water. When pressures are decreased or temperatures are increased, the bicarbonate will begin to decompose, resulting […]
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 […]
