The oil and gas platform is a both structures and equipment. The life of offshore platforms included different phases like: design, construction, commissioning, operation, maintenance, decommissioning and disposal. Each one of these actions may originate project and or specific activity. The jobs of platform for every activities, is in a different period ands and different operator. This paper, provide information by the life and operation of offshore platforms, based to the optimization of engineering and economi...

Determining the optimal location of wells with the aid of an automated search method can significantly increase a project’s net present value as modeled in a reservoir simulator. This work addresses the efficient solution of this problem by using advanced techniques for coupling two important components of autonomic optimization: Dynamic model using Eclipse simulator software (E100), an optimization technique based on the genetic algorithm (GA). Profits and costs during the time period of the project were taken in...

The project No 17005 (2008-2010) is a correlation Subotinac locality in the global wine and gave immense larger investigation of Subotinac (The Aleksinac basin) in respect of geological research. This paper is the result of research by the project of the Ministry of Science and Technological Development No 17005 R. Serbia. Papir presented corelation results of previous prospecting and detailed geological study of the basis for a new supplementary geological and chemical-technological research oil shale in the vici...

This paper is the result of research by the project of the Ministry of Science and Technological Development No 17005 R. Serbia. Some of the results of this collaboration are presented in this paper. The project No 17005 (2008-2010) was carried out research in the locality Subotinac (Aleksinac oil shales deposit). Some of the results of this collaboration are presented in this paper.

The completion string is the most important component in petroleum production system and should be designed and installed precisely, and maintained properly. If the well suffers scale production problem the importance is multiplied. In this study the four major completion techniques commonly used for non-organic depositions is introduced. The subject has been case studied for one of southern Iranian oil wells with inorganic material production problem. The simulations were run using the Prosper software, and were ...

Most crude oils include paraffin that crystallize in low temperature to create cluster, precipitated in the form of sediments and making the free flow of oil more difficult. Such situations take place mainly in the autumn-winter season. Created sediments settle on the surfaces of mining equipment, pipes and reservoirs. This situation cause exploitation difficulties connected with increased flow resistance and in consequence decrease or lack of oil flow in pipelines. In order to protect of pipes and machinery again...

Sedimentation in water reservoirs is a serious problem observed throughout the world. Its reduction is critical to ensure sustained socio-economic development. Mangla reservoir, the largest earth filled reservoir in Pakistan, was completed in 1967 with a gross storage capacity of 7280x106m3. Over the years (1967-99), this dam has been plagued by a massive inflow of sediments resulting in a reduction of 19 \% of its total storage capacity. This led to not only a decreased water supply to the farming community but a...

Helth, Safety and Environmental management program is a dynamic program prepared to exploitation oil and gas offshore. This project program is prepared to accorded ISO standard and Romanian Standard and regulation. This program is following action: proactive programs for the health and safety, identify the source of pollution,-Plan to reuse and recycling the disposal materials,-Enhance the safe management of Naturally Occurring Radioactive Material in processing plants, - Prevent environmental pollution form the d...

The pre-Caspian basin has been formed from Paleozoic to Cenozoic time and the Kashagan field is situated in the southern part of Pre-Caspian depression in the Southern flung of Astrakhan-Aktyubinsk elevation system of basal complex and associated with Tengiz- Kashagan interbasin carbonate platform. The platform is composed of separate carbonate early Carboniferous blocks resting on the common Devonian (late Fransian-Fammenian) carbonate base. Four of them are: Kashagan, Kashagan South-West, Aktote and Kairan are l...

Petrophysics (physics of rocks) is a branch of Natural Science which studies physical properties and behavior of rocks, their change regularity and mechanism, and properties interrelationship. Determination of thermal conductivity, thermal diffusivity and heat capacity is one of the most significant problems in petrophysics. It is necessary for solving a wide range of issues related to natural and artificial thermal fields in the Earth crust: predictions of abyssal temperatures, oil and gas exploration and prospec...

The main goal of core analysis is to reduce uncertainty in reservoir evaluation by providing data representative of the reservoir at in-situ conditions. Core analysis has to be integrated with field and production data to minimize reservoir uncertainties that cannot be addressed with other data sources such as well logging, well testing or seismic. These requirements define the coring objectives, core handling and core analysis scheme. These objectives cannot be achieved by coring a single well. Coring program is ...
