To predict physical properties in a wellbore during oil and gas production, scientists use empirical correlations or mechanistic approach algorithms. The typical research in this field is concentrated on a single property analysis as heat transfer, pressure, temperature, and so forth. Here the most proper correlations, regarding the subject, are presented. And the authors studied how to join all correlations into the full framework which returns all production parameters at every depth in a wellbore. Additionally, the presented simulation results are studied here. Based on presented algorithms, the proper tool has been applied and the results shown in this paper are taken from this application.

This paper gives an overview of erosion mechanisms in elbows in oil and gas production systems. The nature of the erosion process itself makes it very difficult to develop some definitive methods or models to prevent or predict the erosion in elbows in all conditions. This paper provides a review of the subject which will help petroleum engineers to handle the erosion problems in oil and gas industry. This review is given of different erosion mechanisms connected with sand erosion and the factors that influence them, and then the review goes on to look at particulate erosion in elbows in more details. Conclusions are then drawn based on the above analyses.

Simulation Results

Gas hydrates are solid crystalline structures in which water molecules trap small guest gas molecules and encage them through hydrogen bonding. Gas hydrates are known to be problematic in flow assurance applications as they can form plug inside the pipelines during oil and gas production, transportation and processing. In order to inhibit hydrate formation thermodynamically, various chemicals including some alcohols e.g. methanol (MeOH), mono- ethylene glycol (MEG) are used as thermodynamic hydrate inhibitors (THIs). In this paper, a simulation study is performed using PVTsim software wherein it predicts the hydrate formation for pure CO2 solution mixture and CO2 -MEG solution mixture systems using different equation of states. These equations of states include Soave-Redlich-Kwong (SRK), SRK-Peneloux, Peng- Robinson (PR) and Peng-Robinson Peneloux. The simulation results obtained using these equation of states were validated with the experimental data and PRPenelouxEoS was found to be in better agreement. The hydrate formation regions are determined in between the pressure range of 10 to 110 bara for natural gas mixture containing high percentage of CO2 in it. The inhibitors are used in 5, 10 and 20 wt% concentrations. The hydrate inhibition efficiency increased with the increase in concentration. Simulation results showed that methanol performed better in comparison to the other inhibitors at all concentrations.

Operation And Management

As the subject of oil and gas production, reservoir management is the oil production plant’s core business. But at present, there are some problems in reservoir management. For example: the development and management unit is not clear; the organizational structure is not streamlining; management mechanism is not perfect; evaluation is not systematic and so on. So, the oil production plant should focus on those four aspects to explore reservoir management---“unified the ground and underground, clear the input-output” “flattened the management layers, specialized functions structure” “market-oriented economy development, optimize the production process” “long-efficiency business goal , comprehensive evaluation of analysis”

Work Method

The article presents a pre-project study of the rotational work method in the oil and gas industry in terms of technical aesthetics and design. The study aimed to focus the attention of designers on the features of psychological adaptation to this method of work. The database brought together interdisciplinary sources (economics, management, psychology, sociology) and field materials. As a result, a hypothesis was formulated about the aestheticization of the subject-spatial environment as a way to compensate for the stressfulness of the rotational work method. A promising direction for the implementation and verification of this hypothesis is the development of a system of relaxation equipment that accompanies the rotational worker throughout the entire cycle “shift-road-house

This book describes procedures for determining the total hydrocarbon (petroleum) resource or resource potential in a region. Statistical concepts and methods employed in petroleum resource assessment are the subject of the manuscript, extensively illustrated by numerous real case studies. Prof. Lee's computer-aided Petroleum Information Management and Resource Evaluation System (PETRIMES) methodology has been adopted by governments around the world and by major multinational oil companies to perform resource assessment and to predict future oil and gas production. Though this methodology is so widely used, there is no "user's guide" to it, and this book will be the definitive resource for PETRIMES users.

There are many challenging issues toward the tail of the oil and gas production period. An integrated solution is needed considering the economics of the asset. The North Belut field, located at Block B South Natuna Sea, operated by Medco E & P Indonesia has been in operation since 2009. During the current tail of production period, one of the operations challenges is the slugging phenomenon which causes wells shut-in due to high back-pressure and sudden surge of liquid which causes process upset to the downstream facilities. The mitigation program to be implemented should be integrated with the operations strategy to maintain the production and prolong the asset life. This paper summarises the study of the multiphase flowline system at its current operations condition, the impact of lowering plant pressure to the slugging phenomena, and the prediction of slugging tendency in the remaining years of the asset life. The simulation results are based on analysis using the multiphase pipeline simulation tool OLGA with slug tracking module. The results showed that the lowering of the plant pressure can reduce the slugging tendency. However, since the gas will naturally continue to decrease in the end-of-life period, the slugging phenomenon will potentially occur again in the future. The result also shows that the multiphase pipeline behaviours can be modelled with excellent agreement between actual data and simulation results. The result is beneficial in enriching the strategy to reduce slugging in the tail of the production period.
