if solid wastes are not collected and disposed properly, can cause environmental pollution which affect human health, animals and plants. also aesthetic aspect of solid waste disposal is important. therefore proper management is necessary. this study was carried out for the identification and classification of solid waste produced by oil drilling company temporary camps based on rcra act and un...

The continuous development of global economy with decreasing in available hydrocarbon sources and increasing discovery and extraction costs due to decrease in-situ oil and gas reservoir, displays the necessity of using new techniques for the improve rate of penetration and productivity in well. Nanotechnology has already contributed significantly to technological advances in the energy industri...

با توجه به این که حفاری چاه های نفت و گاز به خاطر هزینه بالای آن پرهزینه ترین بخش یک میدان به حساب می آید زمان صرف شده در حفاری تاثیر قابل ملاحظه ای در هزینه نهایی چاه ایفا می کند. بهینه سازی به پارامترهای مطلوبی اشاره می کند که ما را به کمترین هزینه حفاری رهنمون می کند این فرآیند از طریق پارامترهای قابل کنترل و موثر بر نرخ نفوذ همانند وزن روی مته، سرعت چرخش، نوع مته، هیدرولیک و خصوصیات سیال حف...

In this study, three different vegetable-based cutting fluids developed from raw and refined sunflower oil and two commercial types (vegetable and mineral based cutting oils), were carried out to determine for thrust force and surface roughness during drilling of AISI 304 austenitic stainless steel with HSSE tool. The uses of vegetable cutting oils was investigated in reducing thrust force and ...

Formate drilling and completion fluid system is a new type of clean organic salt brine system which has been developed from inorganic salt brine drilling fluid system. It is beneficial to protecte and find hydrocarbon reservoir. Due to the solid free system, the damage of solid phase particles on reservoir, especially low permeability oil and gas layer, can be greatly eliminated, at the same ti...

The 2010 Deepwater Horizon oil spill resulted in 1.6-2.6 × 10(10) grams of petrocarbon accumulation on the seafloor. Data from a deep sediment trap, deployed 7.4 km SW of the well between August 2010 and October 2011, disclose that the sinking of spill-associated substances, mediated by marine particles, especially phytoplankton, continued at least 5 mo following the capping of the well. In Aug...

Today, oil is a strategic commodity in the world that, in addition to focusing on development, makes industrial capacities more active or creates new capacities and industries. Considering the importance of intrapreneurship in the oil and gas drilling industry, the present study was conducted with the aim of interpretive structural modeling of intrapreneurship in the oil and gas drilling indust...

فشار منفذی یکی از کمیت های مهم، در بحث اکتشاف و حفاری اکتشاف منابع هیدروکربوری می باشد. عدم اطلاع از میزان فشار منفذی در لایه های مختلف، قبل از حفاری، سبب ایجاد خطرات جدی مالی و صدمات جانی در حین حفاری چاههای نفت خواهد شد. اطلاع از مقدار این کمیت در نقاط مختلف میدان، باعث کاهش چشمگیر خطرات حفاری و بهبود طراحی چاه طراحی وزن گل و تعیین نقاط نصب لوله جداری در چاه می شود یکی از روشهای جدید تخمین مق...

Managed pressure drilling is a sophisticated pressure control method which is intended to meet increasingly high demands in drilling operations in the oil and gas industry. With this method, the well is pressurized and the drilling mud is released through a control choke which can be used to actively control/reject pressure variations. Such a control system needs to handle several disturbances,...

Generally, the drilling mud is divided into three groups of oil (gas oil) and gas based on its base (the main phase), which is often mixed drilling mud from two or more times a mixture of all three fluids that are present at the same time. In this paper, we first investigate the types of drilling flowers, and then we study the pollution of the types of drilling flowers that...
