Abstract Low oil prices are forcing the oil and gas industry to reduce the well construction cost. This calls for new and more efficient technologies and methods. Cost optimization may have negative impact on the risk level as less resources are available. Even with a strong focus on risk and new regulatory requirements, the well control risk level is not decreasing, but rather shows an increase. A new workflow has therefore been introduced in a collaborative cloud-based well planning system that combines the most advanced transient, multiphase engine with an automated procedure based on drillers method. The workflow will improve the quality of the well control planning as it will enable a simple way of automatic recalculation when the project context is changing. The data flow and quality control of data will also be improved and result in more up to date planning results. The automation of the process removes a huge amount of manual work that up to know has been required to keep the well control calculations synchronized with the project plan. New engine features unique to well control modeling like transient temperature and full compositional tracking adds resolution and accuracy to the well control planning results and helps deliver consistency in the results. The new workflow will deliver well control calculations with better resolution and accuracy with much less effort than what is normal today and should therefore help to reduce risk and cost associated with well planning.

Strategic projects of oil and gas companies regularly overcome the budget. High capitalization of these projects leads to the fact that even small relative cost deviations result in significant additional investments. Under present conditions of economic and political pressure, characterized by a limited opportunity to raise loan capital, there can be no additional investments leading to impossibility of new oil and gas projects realization or stop those being realized. One of the ways to prevent such a negative scenario is to improve the project planning system taking into account the results of monitoring the project portfolio cost deviations. It will not only allow companies to take into account the causes of deviations in several projects, but also help to develop and implement proactive measures.

The impact of corrosion within the refining industry ends up in the failure of components. This failure leads to closing down the plant to scrub the corroded components. Additionally, corrosion normally causes serious environmental issues, namely spills and releases. A vital resource for all those that are concerned within the corrosion management of oil and gas infrastructure, corrosion management within the oil and gas industry provides engineers and designers with the tools and strategies to plan and implement comprehensive corrosion-management programs for oil and gas infrastructures. Control of corrosion is important for continuous production and evading the well control losses. Materials to be used in down hole have to meet certain characteristics to avoid corrosion and provide additional mechanical strenght. It is potential to determine a logical series of steps for material choice, incorporating analysis of the surroundings, corrosion rate calculations, and final material choice based on established limits. Several developments have taken place in refinement the calculation of CO2 corrosion rates. Moreover, the definition of bitter examination has been reviewed and a way wider evaluation of the relevance of varied established and new materials for various service conditions has been created.

The article examines high-risk objects in which it is necessary to monitor its state to prevent hazardous activities during the cycle of preparation of energy resources. The paper examines IT projects that help to if not prevent, then at least minimize the consequences of the negative impact of hazardous industries in process of preparation of energy resources. Due to the fact that currently, there are no uniform and specific requirements for the functionality of such information systems in public services, companies are implementing pilot projects for the implementation of the above tasks. All stages of the pilot project were formed and analyzed in detail. Based on the survey results, the requirements for the functional blocks of the information system were determined. The findings of the study were formed and presented for further use for the project management activities for the company in the oil and gas industry. Implementation of the project in pilot format is the most suitable option in the current conditions. This allows minimizing project risks associated with exceeding the deadlines, budget, as well as inconsistencies of current functionality with the needs of system users by ensuring the possibility of developing and testing the system in a short time and clarifying the future direction of IT solution refinement.

Abstract Objectives April 2010 in the Gulf of Mexico and January 2017 in Oklahoma brought into sharp focus what can happen if the oil and gas industry gets well control wrong: 16 fatalities, significant environmental damage, loss of assets and reputation. Each year we have multiple blowouts and several fatality events due to a loss of well control. The oil and gas industry can improve from a personnel safety, environmental and reputation perspective. The Automation of Well Control will bring a significant step change in the area of Process Safety forwells. It prevents blowouts, reduces all influx volumes, minimising kicktolerance volumes and reducingcasing and well costs. Method A system has been developedwhich enables Automated Well Control whilst in drilling mode. Pre-determined influx rates, agreed by the operator and drilling contractor, and input by the driller are established. Once the system detects the influx, it performs a series of operations by taking control of the drilling rig equipment. The drill string is spaced out, top drive and mud pumps are stopped, and the BOP is closed. All of this occurs without the driller doing anything; however, he can intervene at any moment. Thissystem is designed as an aid to the driller and does not remove his responsibility. Results The Automated Well Control system has been tested on drilling simulators with real drillers. Comparisons tests have shown that the technology enables shut-in times faster than conventional human interface methods, with influx volumes typically 10-20% of those experienced during manual shut-in. Additionally, a full Field Trial using a traditional rigdemonstrated the effectiveness of the system, proving up the functionality under different operational requirements. The system can now be applied to any type of rig worldwide. Over 50 potential modules have been identified. Planned developments forthe system include circulatingout the kick automatically, shut-in for tripping, circulating, cementing and in-flow testing. It provides assurance for afast, safe and effective shut-in.A full Technology Qualification process has been used for this technology. Innovative Technology Over the past 20 years, technology advancements associated with simulators and cyber-rigs have enabled new technologies to be developed. One of these technologies is Automated Well Control. It is believed that this innovative system will enable a step change in the performance ofprocess safety forwell control, dramaticallyreducing major accident hazards, thereby saving millions of dollars per well, reducing environmental impact and preventing loss of life.

Drilling Operations

Over the last decades, the complexity and duration of offshore drilling operations have steadily increased. The size and weight of the risers and BOP stack has grown significantly. These factors have led to an increase in fatigue loads imposed on the wellhead structures during drilling and completion operations. Wellhead fatigue might ultimately lead to loss of well structural integrity and pressure containment and therefore safe and reliable drilling of subsea wellheads has gained high priority in the global oil and gas industry. This paper presents two of the most complex real time instrumentation campaigns for drilling operations. Analyses of a connected drilling riser system including the well structure are complex and involve several engineering disciplines. In addition, there are many unknowns going into the equations when accumulated fatigue damage of the wellhead is estimated. Therefore, assumptions need to be made, very often on the conservative side. A typical example are the global drilling riser analyses where the environmental conditions, actual rig motion and riser / BOP behavior are uncertain. With the duplex scope of accurately documenting the wellhead fatigue status during drilling operations and of achieving a better understanding of the actual risk level of wellhead fatigue, Statoil decided to start a very comprehensive monitoring campaign. Two MODU representing very different generations of rigs in terms of weights and types of equipment were instrumented from topside to BOP connector. Strain gauges were installed around the BOP connector as close as possible to the wellhead in order to capture wellhead response as accurately as possible. Due to the large number of sensors, high accuracy requirement and high sampling frequency of data to be shown live, a cabled solution was selected vs remote battery operated sensors transmitting via acoustic. Double set of cables, sensors and topside equipment were installed in order to make the instrumentation system fully redundant and suited for permanent installation. All data were additionally made available real time onshore to allow the full overview of the operation. To author’s knowledge, these two instrumentation systems are the most comprehensive and complex of this type installed on a drilling riser as of today. The first of the two system was installed approximately three years ago and it is still in operation. This paper describes the instrumentation systems installed and gives an extract of the quality data extracted and already used in already published studies [1, 2, 3].

Environmental Laws

The lack of a realistic estimate of the natural capital largely determines the economic and ecological problems in different sectors of economy. Economically inefficient use of the natural capital leads to its depletion. Flouting of environmental laws, when developing and applying technologies of exploitation of natural resources, has a detrimental effect on the environment, destroying the ecological systems. Exploitation of natural resources in oil and gas industry and development of highly sophisticated natural-engineering systems cause disruption of the ecological balance in the environment and shift in the balance of the environmental components: matter, energy and information. Stabilization of such systems and restoring their disturbed or lost balance puts the attitude towards the environment as a natural system in the forefront. Resistance of this system is regulated by natural environmental laws. Unbiased evaluation of the state of the natural-engineering system in exploitation of natural resources should be given on the basis of the system analysis. Such analysis presupposes interaction and interdependence of all the components and also internal and external interrelations of natural and technogenic subsystems. The analysis requires an integrated approach to consider the processes of use of raw materials, pollution of the biosphere components with hydrocarbons and other substances, and also risk assessment of their negative impact through biogeochemical cycles. Due to the increase of the share of difficult oil, deterioration of its quality, creation of new centres of exploitation of natural resources, it has become essential to find ecologically and economically substantiated solutions taking into account natural laws.

New breakthrough technologies can have a positive or negative impact on the development of the fuel and energy sector. Therefore, the main thing is to evaluate technologies, analyze their suitability for the industry and determine priorities for future opportunities, i.e., identify technologies that provide new advantages for the energy world, and determine how, when and how their impact will become tangible. In this regard, researchers have determined that the innovative technology of the XXI century, recognized to transform the national and global economy is the blockchain technology. The article provides an overview of blockchain technology, defines the principles of its operation and possible applications, i.e., identifies the mechanism of action of the revolutionary system, as well as presents the players of the oil and gas industry to launch blockchain technology and identifies the advantages of innovative technology used in the oil and gas sector. It is determined that on the basis of the new technology, it is possible to create a single network for digitizing all interaction processes and automating them. The study also shows that the scope of application of blockchain in the oil and gas business is much broader, which determines the possibility of further consideration of a wide range of the need for the use of blockchain technology for the oil and gas industry, as well as its impact on the development of oil and gas companies.

Explosion Risk

Management of the risk related to the loss of containment of flammable fluid is paramount to ensure safe operations at facilities processing or storing flammable fluids. According to best industry practice, an extensive set of safety functions—including measures that reduce the frequency of initiating events (e.g. leaks) and measures that mitigate consequences in case of ignition—are implemented in design to control the risk. Adopting the risk-based design principles that are commonly enforced in the oil and gas industry, the performance of implemented safety barriers are assessed both qualitatively and quantitatively using different methodologies such as hazard and operability analysis (HAZOP), failure mode and effects analysis (FMEA), and quantitative risk analysis (QRA). The ultimate outcome from the QRA methodology is used to assess the overall risk level as well as to assess dimensioning accidental loads (DALs) for equipment and structures that will ensure a design that is within the tolerable risk level set for the facility. An accurate assessment of DALs resulting from fires and explosion is crucial to manage both the risk and corresponding cost driving factors. The most critical safety barrier in this regard is to minimise leaks and thereafter to prevent ignition of the dispersed flammable fluid. A fundamental safety design principle is to find ways to avoid the occurrence of incidents rather than implement measures that mitigate consequences. This peer-reviewed paper demonstrates the significance of modelling the safety functions that are in place to ensure that the initial leak does not ignite by presenting a case example for different layouts of a conventional jacket installation with gas turbines. It is concluded that the difference between various available ignition models can be more prominent than the uncertainty related to any other model element in the QRA. To uncover potential hazards not reflected by the model and identify optimal control measures, the effect of the ignition model applied should be investigated in detail for installations where the QRA displays a prominent fire and explosion frequency.
