(author)Natural gas based hydrogen production with carbon capture and storage is referred to as blue hydrogen. If substantial amounts of CO2 from natural gas reforming are captured and permanently stored, such hydrogen could be a low-carbon energy carrier. However, recent research raises questions about the effective climate impacts of blue hydrogen...article 2022

Zhang, J. (author), Meerman, H. (author), Benders, R. (author), Faaij, A. (author)As natural gas (NG) demand increases in China, the question arises how the NG infrastructure fit into a low greenhouse gas (GHG) emissions future towards 2050. Herein, the potential role of the NG infrastructure in supplying low-carbon gases during 2020–2050 for China at a provincial resolution was analyzed for different scenarios. In total,...article 2022

Poort, J.P. (author), Shoeibi Omrani, P.S. (author), Vecchia, A.L. (author)The production optimization of mature gas fields is severely complicated by the occurrence of certain undesired well events such as salt precipitation, liquid loading, or gas/water coning. Learning from production data of periods in which such events have taken place could help operators improve the process optimization. However, due to the...conference paper 2020

Paap, B. (author), Kraaijpoel, D. (author), Wassing, B. (author), van Wees, J.D. (author)Numerical simulations of seismic wave propagation usually rely on a simple source modelconsisting of an idealized point location and a moment tensor. In general, this is a validapproximation when the source dimensions are small relative to the distance of points at whichthe seismic wave motions are to be evaluated. Otherwise, a more realistic...article 2020

Saeed, A. (author), Volker, A.W.F. (author), Martina, Q. (author), Alalouni, A. (author)Scale and corrosion affect the production certainty of oil and gas well. Scale build-up reduces flow and ultimately could shut down production when it block to tubing completely. Corrosion of the tubing wall occurs very often simultaneously with scale build-up and affects the integrity of the tubing wall. Vital information about the integrity is...conference paper 2019

Vandeweijer, V. (author), Hofstee, C. (author), Graven, H. (author)Since 2004 the feasibility of CO2 injection and storage in depleted natural gas fields has been researched and demonstrated at K12-B, a gas field on the Dutch continental shelf. In total over 100 Kton of CO2 was injected. The entire operation at the K12-B field was completed without any major complications. It can therefore be stated that safe...conference paper 2018

Loh, K.K.L. (author), Shoeibi Omrani, P. (author), van der Linden, R.J.P. (author)The forecasting of gas production from mature gas wells, due to their complex end-of-life behaviour, is challenging and often associated with uncertainties (both measurements and modelling uncertainties). Yet, having good forecasts are crucial for operational decision making. In this paper, we present a purely black-box based approach, which...conference paper 2018

Steenbergen, R.D.J.M. (author), Vrouwenvelder, A.C.W.M. (author)In the Dutch province of Groningen over the last year shallow earthquakes are induced due to large scale gas extraction from the gas field at 3 km depth. The induced earthquakes differ from the better known tectonic earthquakes all over the world, caused by movement of the earth at large depths. The structures affected by the earthquakes however...conference paper 2017
