Oil And Gas Production

It is necessary to carry out work to analyze the harmful factors of accidents during the production, operation and transportation of raw materials in oil and gas fields and assess their compliance with the requirements of the standards of the Republic of Kazakhstan. The main goal of labor protection is to create safe working conditions for employees, as well as to prevent personnel from illnesses. In this regard, it is necessary to have a system of accounting, analysis and assessment of the state of labor protection, as well as management of labor protection. This article proposes ways to quickly assess the state of health and safety at work by calculating a number of occupational risk indicators based on information available in the modules for assessing occupational safety by industrial risk indicators. The efficiency of using the OSH management systems software proposed by the authors is based on a specific task from four main modules "Employees", "Events", "Equipment", "Ecology" and a number of submodules. In addition, this work uses matrix methods for assessing risks in the "Probability or Consequences of an Event" coordinate system, "Elmeri" system, "Fine Kinney" method, "Risks". Modern expert methods are compared and presented under the title "Five stages of assessment"

As the treated water from offshore oil and gas production is discharged to the surrounding sea, there is an incentive to improve the performance of the offshore produced water treatment, to reduce the environmental pollutants to the sea. Regulations determine both the maximum allowed oil concentration and the total annual quantity. It is reasonable to assume that when better separation equipment or methods are developed, the regulation will become more strict, and force other producers to follow the trend towards zero harmful discharge. This paper develops and validates a hydrocyclone model to be used as a test-bed for improved control designs. The modeling methodology uses a combination of first-principles to define model structure and data-driven parameter identification. To evaluate and validate the separation performance, real-time fluorescence-based oil-in-water (OiW) concentration monitors, with dual redundancy, are installed and used on sidestreams of a modified pilot plant. The installed monitors measure the inlet and outlet OiW concentration of the tested hydrocyclone. The proposed control-oriented hydrocyclone model proved to be a reasonable candidate for predicting the hydrocyclone separation performance.

Large amounts of produced water are generated during oil and gas production. Produced water, as it is known in the oil industry, is briny fluid trapped in the rock of oil reservoirs. The objective of this study was to test produced waters from a Montana USA oilfield using a mobile station to design a plant to cost efficiently treat the produced water for agricultural irrigation. We used combined physical and chemical treatment of produced water in order to comply with reuse and discharge limits. This mobile station consists of three stages: pretreatments, membrane filtration and post treatment. Two spiral-wound membrane units were employed and the rejections of various constituents were examined. The performance of two membranes, 20 kDa weight cut-off (MWCO) ultrafiltration and a polyamide-composite reverse osmosis membrane was investigated. The mobile station effectively decreased conductivity by 98%, COD by 100% and the SAR by 2.15 mgeqv0.5 in the produced water tested in this study. Cost analysis showed that the treatment cost of produced water is less expensive than to dispose of it by injection and this treated water may be of great value in water-poor regions. We can conclude that the mobile station provided a viable and cost-effective result to beneficial use of produced water.

.Instability of the global energy market and internal problems of operation of the mature Orenburg oil and gas condensate field have led to the need for innovation. The relevance of new technologies is explained by the fact that since 1967, the development of the field has been complicated by the aggressiveness of the extracted hydrogen sulfide gas and the activity of water manifestations. The lack of effective technologies has led to a deterioration in the conditions of field preparation of raw materials, a drop in reservoir pressure and flow rate of wells, and an increase in their water content. As a result, oil and gas production and environmental and economic efficiency indicators are rapidly declining. In this regard, priorities have been set for technological improvement of subsurface use: 1) reduction of operating costs through the introduction of resource-saving and energy-efficient technologies; 2) application of environmental innovations in order to reduce the man-made impact on the environment. This paper presents measures aimed at solving the identified problems: re-equipment of oil wells with an automated plunger-lift on solar batteries without reconstruction of fountain fittings; arrangement of a system for utilization of gases degassing of sulfur on the Claus process plant;etc.

This work conducts a technical analysis of the current production and consumption of vegetable oils and some of the oily byproducts to determine the potential feedstock for the synthesis of non-food-competitive surfactants and surfactant-based systems. It defines the concentrated phosphatides (phosphatidic sludge) as no-/low- value streams, appropriately suited for chemical valorisation. The study further creates biobased surfactants by amidation of phosphatidic sludge derived from refinery of sunflower and rapeseed oils with monoethanolamine, N-(2-hydroxyethyl)ethylenediamine, or N,N’-bis(2-hydroxyethyl)ethylenediamine, under the action of calcium hydroxide as catalyst in excellent yields (95–98 %). Besides waste remediation, the use of phosphatides enabled to create the mixed surfactant compositions, comprising fatty acid alkanolamides and calcium glycerolphosphatides with improved solubility in organic non-polar solvents. With new surfactants, there have been created reversed emulsion systems, which can be potentially applied to the development and exploitation of gas and oil deposits are recommended for drilling wells, the disclosure of productive strata; perforation of wells and development of productive layers; blockage of gas, gas condensate and oil wells; elimination of manifestations and flow of gas in wells; limitation and elimination of waterways; cleaning of the hollow zone of wells and intensification of the inflow of hydrocarbon raw materials, which have been tested in laboratory and experimental industrial conditions, and a significant part of them have been introduced or tested on gas condensate fields. Creation of coordinated, effective and economical actions that should be formed in the state energy policy of Ukraine would facilitate the development of oil and gas companies, namely: increase of own oil and gas production; maximizing the potential of energy saving; diversification of external sources of supply; approximation of the parameters of the oil and gas industry to the norms and standards of the European Union.

Introduction. The paper registers some significant changes that higher mining education has undergone over the past decades, including the ones that occurred in Germany. Mineral production on the Eurasian continent has been decreasing gradually and resulted in the declining demand for mining specialists. It is in German that the tendency was the most pronounced. Reduced number of students and the subsequent reduction in the number of mining and geological departments concerned all leading centers of mining education. Relevance. Higher educational institutions in Germany are looking for a way out of the crisis reorienting their teaching and scientific activity to the allied sciences, in particular oil and gas production, underground engineering structures construction, production and processing of unconventional natural resources, subsea production, environment-related activities, and spoil disposal. Colleges also train specialists for other countries and international mining corporations. Methods of research. The paper provides examples and analysis of new curricula in the universities of Freiberg, Aachen, Clausthal, etc. These mining schools have accumulated considerable experience in reforming and developing mining education. Current state. The mining field of vocational training in German colleges has acquired an integrated name which can be translated as the “technology of mineral raw materials”. Traditional mining specialisms are being combined and consolidated. New methodological approaches are being extensively introduced. These steps are to improve the appeal of the mining education for the youth and arouse employers interest in the specialists of a new specialism.

Rail Service

Burgeoning oil and gas production in Texas with the application of hydraulic fracturing (fracking) and horizontal drilling techniques has dramatically impacted the condition of rural roadway infrastructure. Many rural roadways are now inundated with trucks traveling to and from oil and gas well areas. Recent estimates indicate that each horizontal well requires over 2,000 truckloads for construction, drilling operations, maintenance, and crude oil transport over the life of the well. Rail has been an active partner in oil and gas exploration by shuttling fracking sand and drilling supplies to the oil and gas regions and transporting crude and petroleum products from the regions not served by pipelines. This partnership is restricted by limited rail service points and infrastructure close to the active wells; however, expanding existing rail services and network infrastructure could move rail operations closer to the active production areas. The cost and safety impacts of extreme reduction in pavement life may be offset substantially with increased use of rail transport closer to drilling locations. This paper examines the potential options regarding expanded use of rail transportation to address the growing costs of roadway rehabilitation in energy production areas in order to reduce roadway network impacts. Rail service expansion can be through better use of the existing freight rail network, increasing the number of and better placement of transloading facilities along the rail network, and/or through improved rail capacity from double tracking or extending new rail lines. Both the private and public sectors potentially could play a role. A number of privately developed transloading facilities have sprung up along existing rail lines, attempting to deliver fracking sand, pipe, and other supplies. Additionally, public economic development corporations have been actively pursuing development. Expansion of the railroad network could come through the use of special districts such as Rural Rail Transportation Districts (RRTDs), Regional Mobility Authorities (RMAs), or through reactivation of abandoned rail lines. These trends are also examined.
