(author)Field development planning activities involve decisions that entail multi-billion-dollar investments. Making right design choices is crucial to the techno-economic success of the project. In this paper we demonstrate how state-of-the-art numerical model-based optimization techniques can support asset teams in this complex decision-making process...conference paper 2023

Egberts, P.J.P. (author), Peters, E. (author)Radial Jet Drilling (RJD) is a stimulation technique to increase a well’s performance through creation of multiple laterals of up to 100 m long. The technique has been used in the petroleum industry for several years and recently also for geothermal reservoirs. Interpretation of well tests of a well with multiple laterals may become problematic...article 2022

Bijl, P.K. (author), Houben, A.J.P. (author), Bruls, A. (author), Pross, J. (author), Sangiorgi, F. (author)There is growing interest in the scientific community in reconstructing the paleoceanography of the Southern Ocean during the Oligocene-Miocene because these time intervals experienced atmospheric CO2 concentrations with relevance to our future. However, it has remained notoriously difficult to put the sedimentary archives used in these efforts...article 2018

(author)Wave propagation of electro-optical systems, lasers or imaging depends on the state of the atmosphere their beams are passing through. Fluctuations in the refractive index of air are responsible for signal attenuation and image degradation. This atmospheric effect is called optical turbulence and its strength is quantified by the structure...conference paper 2018

TerHeege, J.H. (author), Orlic, B. (author), Wollenweber, J. (author)Geothermal drilling environments are often hostile to well materials, especially in magmatic settings where properties of well casing and cements may rapidly change as a result of high temperatures and chemically active formation fluids. Prolonging the lifetime of such geothermal wells is one of the key challenges to achieve a commercially...conference paper 2017

Analysis of underwater acoustic propagation in a harbour environment and its effect on communicationBinnerts, B. (author), Blom, K.C.H. (author), Giodini, S. (author)Acoustic underwater communication is an enabler for the use of autonomous underwater vehicles (AUVs). AUVs can operate in acoustically challenging environments, e.g., near offshore platforms and in harbours. To realize robust underwater communication in such environments, the propagation conditions need to be properly understood. In this paper,...conference paper 2017

(author)One of the main activities in the (re-)development of large hydrocarbon fields is the drilling of new wells. The drilling process may involve a large number of wells and take several years to complete. Challenges include the selection of a limited set of wells from many possible well paths, and the scheduling of the drilling itself....conference paper 2016
