San Antonio-based Petro Waste Environmental (PWE) announced the opening of its newest state-of-the-art nonhazardous oil and gas waste landfill facility in Howard County, Texas. Milestone Environmental Services has announced the ground breaking for its new oilfield waste-disposal facility south of Midland, Texas.
Offshore oil and gas installations are (by their nature) located in remote locations that are both difficult and costly to access. While such challenges exist, the operate & maintain requirements associated with such assets are consistent and must be addressed, requiring operators to identify the most efficient form of service to reduce staffing levels, risk and cost.
Offshore hydrocarbon production assets commonly incorporate equipment and processes that can lead to significant (fugitive) gas emissions. The consequences are both economic and social (environmental) in nature, requiring operators to perform emissions surveys with the objective of leak identification and remediation within the shortest possible timeframe. The frequency of this activity is naturally limited and must be balanced with the staffing and operating needs of the broader facility, which in-turn can lead to sub-optimal leak detection to fix timing and reliability.
Addressing the three key challenges of access productivity, detection reliability and results quantification, Worley has developed a remote sensing platform that incorporates the use of productive remote access equipment such as unmanned aerial vehicles (UAV) and in-situ monitoring, with machine based emissions detection and algorithmic quantification to provide a solution that allows the operator to increase survey frequency, obtain more reliable results at lower cost, and perform the work in a manner consistent with safe and low-risk operations.
In both testing and field deployments, the results have provided for significant reductions in both false positive and negatives and have produced datasets that allow for accurate indications of greenhouse gas reduction via comparison of volumetric emissions before and after leak repair activity has taken place.
The technology is largely mathematical, utilizing coded routines for machine learning to perform gas detection under (initially) supervised modeling conditions, and algorithmic gas dispersion models for further emission quantification. The performance of the survey is typically carried out through the integration of existing, proven manufactured sensing equipment across several types of UAV or in-situ monitors which collect field data for transmission to a cloud-based portal which further processes the results.
The approach has been shown effective in accessing hard or costly to reach areas, improving survey productivities, while the data processing and quantification allows the operator to benefit from improved measurability and prioritize leak repair accordingly.
Innovation is critical to the future success of the oil and gas industry (
As a way of addressing this, the TechX programme at the Oil & Gas Technology Centre has launched TechX Ventures in July 2018 – a partnership with Deep Science Ventures (DSV) – that combines deep science with engineering to create the next generation of start-up companies with technologies that will position the oil and gas industry for a sustainable future in a low carbon economy.
The start of the programme was a workshop held with industry, academia and the scientific community, to identify areas where new thinking and technology could open up significant opportunities. Three challenge themes were developed, each of which became an opportunity areas for DSV to address. These are:
As part of the TechX Ventures programme, DSV recruited thirty scientists and engineering experts from across the world to tackle the opportunity areas and at the end of the nine-month programme a total of six new start-up companies with new intellectual property were created and invested in by DSV. Of these six, two were selected to join the coveted TechX Pioneer accelerator programme run by OGTC in Aberdeen. These companies are called Eltera and Optic Earth.
We all identify the need to integrate climate change into corporate strategy, with a profitable Carbon Capture Utilisation & Storage (CCUS) business model the elusive goal. Today, CCUS forms 10% of the R&D program of Total, a founding contributor to the OGCI Climate Investments fund. Here in the North East of Scotland, UK and Scottish Governments, along with project developer Pale Blue Dot Energy and Total are providing match funding to the European Commission’s Connecting Europe Facilities fund to progress feasibility work on the Acorn CCS project. As society continues to drive an expectation beyond hydrocarbons, what proposal might the North East of Scotland offer in response?
To meet ambitious emissions reduction targets, the UK must envisage radical changes to the energy economy. Already affecting power generation, these changes must drive further into transport and domestic/industrial energy consumption. Two technologies which may play a part in the decarbonisation of the UK energy business are CCUS and the use of Hydrogen as an energy carrier and energy store, with several studies showing that clean hydrogen is potentially the lowest cost route to meeting UK emission targets in multiple sectors. This builds on the UK’s world class gas network infrastructure, which can be repurposed to avoid becoming stranded, avoiding the enormous expense of increasing the capacity of the electricity transmission network, much of which would lie idle during the summer. The UK gas network carries approximately three times more energy than the electricity network, at one third the unit cost to consumers, and meets winter peaks that are five times greater.
Different to previous CCUS projects, and having the Oil and Gas Authority (OGA)’s first carbon dioxide appraisal and storage licence award, ACORN is an opportunity to evaluate a brownfield CCUS solution to capture, transport and store post-combustion CO2, combined with an upside through emerging pre-combustion CO2 capture technology relating to the production and sale of bulk hydrogen produced from natural gas with a zero-emission target. Located at the St Fergus Gas Terminal – an active industrial site where around 35% of all the natural gas used in the UK comes onshore. ACORN is designed as a "low-cost", "low-risk" CCUS project, to be built quickly, taking advantage of existing oil and gas infrastructure and well understood offshore storage sites. The Acorn Hydrogen project undertakes to evaluate and develop an advanced reformation process which will deliver the most energy and cost-efficient industrial hydrogen production process whilst capturing and sequestering CO2 emissions. An initial phase offers a full-chain demonstration project, an essential step toward commissioning the concept and subsequent commercialisation of large-scale CCUS and Hydrogen deployment in the UK.
SPE Offshore Europe represents an ideal opportunity to update both the region and industry on results, observations, and conclusions with respect to the evolving development architecture, selected process technologies, Government and gas transportation regulatory engagement as this, the leading Scottish CCS project continues its journey toward a final investment decision.
The UK and the international community have an increasing interest in the benefits of a hydrogen-based economy. Existing and emerging technologies that are inherently carbon-neutral and potentially carbon-negative are increasingly attractive, given the challenge of meeting climate targets to prevent climate change and build a clean growth strategy. The integration of clean energy technologies across the UK Continental Shelf (UKCS) can increase the flexibility of the energy system, driving efficiency, cost reduction and enhancing the value of natural resources.
There are over 250 platforms and 45,000 kilometres of pipeline installed within the United Kingdom Continental Shelf (UKCS). As these assets near the end of their economic life oil and gas operators are planning to decommission these facilities in an efficient and cost-effective manner. Current cost forecasts for this activity exceed £58bn with approximately 50% borne by the operators and 50% borne by UK taxpayers.
The Hydrogen Offshore Production (HOP) project identifies an alternative to decommissioning by providing re-use options for offshore infrastructure while addressing the national challenge of a low carbon energy supply. In doing so, the project will prove the feasibility of several decentralised hydrogen generation, storage and distribution options that collectively provide a scalable offshore hydrogen production solution, whilst offsetting a portion of decommissioning costs that are currently forecast for all offshore assets and infrastructure.
HOP will tackle the challenge of bulk hydrogen production by (1) proposing viable environmental and economic technology solutions to be deployed offshore, (2) developing a new Industrial Hydrogen Production test site to both prove the industrial benefits and to aid commercialisation of emerging technology and, (3) conducting market analysis and producing the business case for the transformation of existing offshore infrastructure, re-purposing assets and demonstrating the viability for decentralised generation of hydrogen.
As part of the project, an Industrial Hydrogen Production test site will be established with Flotta (Orkney Islands) being proposed as the location. This will provide a test bed for technology, fast-tracking its development and providing a route for accelerated commercial deployment. Within a region of considerable renewable energy generation, the island of Flotta is ideally placed to benefit from local expertise, existing supply chain and advanced technology solutions. For example, the Industrial Hydrogen Production test site would greatly benefit from lessons learnt at the nearby Orkney Water Testing Centre.
The interest in on Carbon Capture and Storage (CCS) has increased over the last years with recognition of the ability of CCS to achieve a great reductions in CO2 emission as the fossil fuels will continue to be the main supplier for the world energy demand for the upcoming decades with no other alternatives are forecasted to replace them. The comparison between CCS and the other future alternatives or options relies mainly on the CCS cost -which is the main focus of this paper- removal of CCS deployment barrier in addition to the barriers and costs for the alternative options for CO2 emission reduction.
This study gives an insight comparison between the electricity cost for five different options of power generation including Combined Cycle Gas Turbines (CCGT) without and with CCS, coal and finally the nuclear power plants. In addition, it determines the ranges of fuel and carbon prices at which each option can be economically deployed
The recent coal CCS for Nth of a kind power generation plant cost estimates lie in the region of 60 to 100 $/ton of avoided CO2 which is higher than the previous CCS cost estimated and also greater than the accepted range of the forecasted carbon prices in the upcoming years. The higher costs of coal CCS would suggest the following: Coal CCS power generation plants is way less economical than gas ones for the range of carbon prices less than 60-100 $/ton of avoided CO2 Even at carbon prices higher than 100 $/ton of CO2, coal CCS power plants still produces higher cost electricity when compared to the gas CCS ones as long as the natural gas prices are still lower than 9 $/MBTU Coal CCS electricity costs are still higher when compared to a nuclear power plant option

Even at carbon prices higher than 100 $/ton of CO2, coal CCS power plants still produces higher cost electricity when compared to the gas CCS ones as long as the natural gas prices are still lower than 9 $/MBTU
Coal CCS electricity costs are still higher when compared to a nuclear power plant option
It is widely believed that the CCS power plants (Gas or Coal) are not expected to be economical over the upcoming years, however introduction of subsidized forms of CCS are likely to take place. Also, CCS technology components are expected to be economically implemented in operations like Enhance Oil recovery (EOR), so, in this paper, an economic evaluation is provided for using of CO2 extracted from natural gas plant into EOR operations. CO2 separation cost in the natural gas processing industry is less than the capture cost of CO2 in power plants as a result of its high gas pressure and the fact that CO2 removal is mandatory to increase the value of a natural gas resource
On the other hand, this is not the case for the CCS of the most industrial emissions, as they are expected to be higher than those of power plants as a result of the smaller scale and wider distributed CO2 streams compared to power generation plants. This shows the importance of the realistic CCS cost estimation as a significant factor in the R&D projects and implementation trials that try to overcome the tackles that face the application of such promising technologies.
As a result of the 2016 Paris agreement, the challenge of climate change and the imperative of moving to a low carbon economy has intensified. This challenge has been added to the traditional objectives of affordable and secure energy sources. These three criteria are the basis for the Energy Transition. Increasingly, investors, consumers and policy makers are looking to energy businesses to reflect all these criteria as the basis of their company culture and objectives.
This paper looks to explore opportunities for the UK oil and gas industry to further align itself with the drivers set out above and continue to promote investment into a sector that is key to delivering the Energy Transition:
Improved communication of carbon reduction and mitigation efforts at both a national and global level Increased collaborative efforts aimed at reducing emissions resulting from exploration and production offshore The potential for UKCS oil & gas companies’ involvement in carbon mitigation and storage
Improved communication of carbon reduction and mitigation efforts at both a national and global level
Increased collaborative efforts aimed at reducing emissions resulting from exploration and production offshore
The potential for UKCS oil & gas companies’ involvement in carbon mitigation and storage
Over recent years, the offshore UKCS oil and gas sector has focused on improving cost efficiency in its offshore operations. This implies a commitment to continuously improve environmental performance despite the challenges of doing so in a maturing oil and gas basin, where maximising economic recovery from fields requires greater effort. Notwithstanding these challenges, the overall long-term trends in environmental performance are improving as a result of efforts by the industry.
Moving forwards, the benefits of effective emissions management will continue to intensify, beyond the regulatory requirements of environmental protection, as a result of two key drivers:
To maintain investor and public confidence – reducing both the carbon footprint of operations and carbon intensity of products used by consumers, will help position companies for a lower carbon economy. The business case - EU ETS Phase IV is modelled to cost the sector £2.2 billion from 2021 to 2030 as the cost of allowances is projected to increase combined with the reduction in free allowances. Therefore, reducing emissions at installations will continue to be imperative for improved environment performance as well as the continued economic viability of the installation.

The sector must therefore continue to adapt to these ongoing fundamental changes that are taking place in energy supply more widely. As with any industry, businesses need to respond to shifting economic and societal demands and the consequent changes in energy needs. Hence, the effective management of emissions must proliferate through both operations (exploration, production and transportation of hydrocarbons), and use of the products delivered.

The joint research project "MUM - Large Modifiable Underwater Mothership" targets the development of a highly modular, unmanned underwater vehicle, which allows a mission dependent module assembly to fulfill a wide spectrum of underwater tasks. The paper presents a case study for the deployment and recovery of ocean bottom nodes (OBN) for seismic surveys. Therefore, a specific vehicle configuration and its functionality is introduced. The advantages of MUM are presented in terms of its cost efficiency and non-monetary benefits, as crew safety, carbon footprint and others. In addition, business aspects for potential customers are discussed.
The major challenge facing society in the 21st century is to improve the quality of life for all citizens in an egalitarian way, by providing sufficient food, shelter, energy and other resources for a healthy meaningful life, whilst at the same time decarbonizing anthropogenic activity to provide a safe global climate. This means limiting the temperature rise to below 2 C. Currently, spreading wealth and health across the globe is dependent on growing the GDP of all countries. This is driven by the use of energy, which until recently has mostly derived from fossil fuel, though a number of countries have shown a decoupling of GDP growth and greenhouse gas emissions from the energy sector through rapid increases in low carbon energy generation. Nevertheless, as low carbon energy technologies are implemented over the coming decades, fossil fuels will continue to have a vital role in providing energy to drive the global economy. Considering the current level of energy consumption and projected implementation rates of low carbon energy production, a considerable quantity of fossil fuels will still be used, and to avoid emissions of GHG, carbon capture and storage (CCS) on an industrial scale will be required. In addition, the IPCC estimate that large scale GHG removal from the atmosphere is required using technologies such as Bioenergy CCS to achieve climate safety. In this paper we estimate the amount of carbon dioxide that will have to be captured and stored, the storage volume and infrastructure required if we are to achieve both the energy consumption and GHG emission goals. By reference to the UK we conclude that the oil and gas production industry alone has the geological and engineering expertise and global reach to find the geological storage structures and build the facilities, pipelines and wells required. Here we consider why and how oil and gas companies will need to morph into hydrocarbon production and carbon dioxide storage enterprises, and thus be economically sustainable businesses in the long term, by diversifying in and developing this new industry.
