Accelerating geothermal development with a play-based portfolio approach

Over the past decade in the Netherlands, most operators have only developed a single doublet. The learning effect from these single events is suboptimal, and operators have only been capable of developing doublets in areas with relatively low exploration risk. This 'stand-alone' approach can be significantly improved by a collective approach to...

Informed production optimization in hydrocarbon reservoirs

The exploitation of subsurface hydrocarbon reservoirs is achieved through the control of production and injection wells (i.e., by prescribing time-varying pressures and flow rates) to create conditions that make the hydrocarbons trapped in the pores of the rock formation flow to the surface. The design of production strategies to exploit these...

Quantifying efficiency of field-wide surveys for verifying CO2 plume conformance during storage operations

Managing the risk of unexpected events occurring during site operations and reducing operational costs are paramount to ensure the success of CO2 storage projects. For this purpose, operators need to design cost-effective monitoring systems to detect signals that can indicate whether or not the storage site behaves as expected and will continue...

Quantifying the efficiency of surveillance strategies for subsurface CO2 storage applications

In this paper we address the challenge of efficient and reliable monitoring of subsurface CO2 storage operations for conformance verification purposes. In order to acquire a storage license, the operator has to demonstrate convincingly to the regulator that the operation of the site will conform to safety regulations, and that CO2 will remain...

Online adaptation of path formation in UAV search-and-identify missions

In this paper, we propose a technique for optimisation and online adaptation of search paths of unmanned aerial vehicles (UAVs) in search-and-identify missions. In these missions, a UAV has the objective to search for targets and to identify those. We extend earlier work that was restricted to offline generation of search paths by enabling the...
