If proven economic, solar EOR technology could represent an environmentally and energy friendly solution for California’s heavy oil producers. Oil and gas professionals may not consider solar power to be a serious threat, but it is poised to make serious inroads into the heating and cooling market. Shell invested in a Singapore solar company and signed an agreement to purchase a Texas company with solar and other renewable assets. Along with its minority stake in a company that uses solar to generate steam for EOR in the Middle East, Shell catches some rays in the Asia Pacific, US, and Oman. In thermal enhanced oil recovery there is one big ingredient: steam.

From the highest courts of the US judicial branch to the C-suite, contests involving patents have recently come to the fore in the innovation hungry US oilfield services industry, even as filings and litigation have declined in recent years. Seeking out, experimenting with, and ultimately embracing technologies from other industries have proven crucial to innovating at oilfield service firms such as Halliburton, which has tried everything from dog food to submarine tech to improve its work downhole. R&D may be the key to the survival of companies as the new economics of the industry take hold. The R&D Technical Section dinner at ATCE drew varying perspectives as the panelists discussed, and sometimes debated, a range of approaches to safeguarding industry viability and growth in the years ahead. Even as the oil and gas industry looks for the next great idea to propel it forward, it should constantly reconsider past innovations for inspiration, the CEO of a major operator said Monday on the opening day of 2017 SPE ATCE.
US crude oil production is expanding at an unprecedented rate, but much faster growth will be needed in the next few years to meet the world’s demand if global investment in conventional supply doesn’t pick up, an IEA report indicates. If proven economic, solar EOR technology could represent an environmentally and energy friendly solution for California’s heavy oil producers. The world still needs oil and gas, but it is also making room for renewable energy which will change how upstream companies do business. The top US wind power official told the offshore upstream sector that it can help build “smaller, leaner, and cheaper" wind turbine farms. Compared to oil in the ground, the sun looks like a limitless energy source.
The oil and gas industry will continue to play an essential role in meeting the growing world energy demand for decades to come. A fact sometimes overlooked is that the industry is also a major consumer of energy and a contributor to Greenhouse Gas (GHG) emissions. In recent years, there has been increasing interest in the use of renewable energy in the oil industry. Various technologies are used to produce renewable energy, from solar radiation to harnessing the power of the wind and sea. The application of different types of renewable energy in oil and gas fields is reviewed. The advantages and limitations of each technology are discussed. This paper presents the state of the art on current and potential applications of the different technologies of renewable energy in the oil and gas industry. The paper demonstrates that using renewables offer many advantages including saving hydrocarbon resources, minimizing the oil industry's GHG emission and enhancing its public image.
The course goes through fundamentals of demand and supply in global energy markets, main primary energy sources (conventional and unconventional oil and gas, coal, renewables, and nuclear), electricity markets. Global energy scenarios are then presented with their impact on the world’s energy-related CO2 emissions and the oil and gas industry’s investments. This course is intended for technical, management, R&D, and HSE communities. All cancellations must be received no later than 14 days prior to the course start date. Cancellations made after the 14 day window will not be refunded.

A fatigue test has been conducted on a large-scale offshore wind turbine grouted connection specimen at the Leibniz University of Hannover. For detecting damages in the grouted joint, a structural health monitoring (SHM) system based on fiber optic sensor-type fiber Bragg grating (FBG) has been implemented. By extracting the features of the FBG signal responses using the Wigner–Ville distribution (WVD) and one of its marginal properties, the energy spectral density (ESD), it is possible to detect the occurrence and the global severity of the damage. Some information about the local severity of the damage has also been obtained.
The grouted connection consists of the high-performance grout-filled space between the two structural steel components of respectively the sleeve and the pile of offshore wind turbines (OWTs). For monopile OWTs, it is located around the water level between the transition piece and the pile, whereas for jacket and tripod OWTs, it is located just above the seabed, between substructure and foundation pile. While grouted joints for monopiles are exposed to bending moments, grouted joints for latticed substructures (tripods and jackets) are exposed to predominant axial loadings and low torsional moments (Schaumann and Böker, 2005; Schaumann, Lochte-Holtgreven et al., 2010). It is a critical structural part of OWTs. In 2009–2010, engineers reported grouted connection failures causing slight and progressive settlement of turbines. The problem affected approximately 600 of the 988 monopile wind turbines in the North Sea, requiring further investigations concerning the design of the grouted connection (Rajgor, 2012). Since then, two grouted connection designs reducing the axial forces in this area have been recommended by Det Norske Veritas (2014): using a conical grouted connection (first design) or a tubular connection with shear keys (second design).

During the Offshore Code Comparison Collaboration, Continued, with Correlation (OC5) project, which focused on the validation of numerical methods through comparison against tank test data, the authors created a numerical FAST model of the 1:50-scale DeepCwind semisubmersible system that was tested at the Maritime Research Institute Netherlands ocean basin in 2013. The OC5 project revealed a general underprediction of loads and motions by the participating numerical models. This paper discusses several model calibration studies that were conducted to identify potential model parameter adjustments that help to improve the agreement between the numerical simulations and the experimental test data. These calibration studies cover wind-field-specific parameters (coherence, turbulence), and hydrodynamic and aerodynamic modeling approaches, as well as rotor model (blade-pitch and blade-mass imbalances) and tower model (structural tower damping coefficient) adjustments. These calibration studies were conducted based on relatively simple calibration load cases (wave only/wind only). The agreement between the final FAST model and experimental measurements is then assessed based on more complex combined wind and wave validation cases. The analysis presented in this paper does not claim to be an exhaustive parameter identification study but is aimed at describing the qualitative impact of different model parameters on the system response. This work should help to provide guidance for future systematic parameter identification and uncertainty quantification efforts.

This study investigated a vibration and tilt monitoring system for an offshore wind turbine constructed using a high-rise-pile- cap supporting foundation, which is the first offshore wind power project in South China with a batholith seabed. The analysis of data collected by the system during the 2016 typhoon Meranti showed that the typhoon significantly affected vibration and instantaneous tilt of the supporting system without any significant change to the first natural frequency. Additionally, it did not produce any permanent inclination, indicating that no serious structural failure occurred under the influence of the typhoon. However, during the typhoon, the vibration acceleration, vibration intensity, and the effective inclination of the high-rise-pile-cap supporting system using rock-socketed piles were smaller than those with driven frictional piles, indicating that the former is better than the latter in terms of resistance to vibration and tilt.
The construction of offshore wind power plants in China faces many challenges, including the raging typhoons in the East and South Seas. Each year, the Guangdong province experiences typhoons three times on average, accounting for 33% of the annual typhoons in China’s coastal areas. The proportions of typhoon episodes in Taiwan, the Hainan province, the Fujian province, and the Zhejiang province are 19%, 17%, 16%, and 10%, respectively (Wu and Li, 2012). The extreme vibration and abnormal inclination of the offshore wind turbine supporting system as a result of typhoons sometimes lead to structural failures and can even result in the collapse of the wind turbine structure into the ocean.
