This study discusses the potential of the in-depth water diversion (IDD) process to enhance oil recovery from subsurface reservoirs and investigates IDD strategies through an ensemble optimization approach. Pilot studies in the North Sea performed in recent years have shown that Sodium Silicate can be applied as blocking agent, diverting water...

As of 2040, Energy Information Administration (EIA) expects an increase of 28% in world energy consump- tion. The majority of this consumption is projected to account from developing countries such as India, China and other third world countries since the economy is increasing rapidly. [3]
In order to overcome this fast increase, the human...

We present a novel nonlinear formulation for modeling reactive-compositional flow and transport in presence of complex phase behavior due to combination of thermodynamic and chemical equilibrium in multi-phase systems. We apply this formulation to model precipitation/dissolution of minerals in reactive flow in subsurface reservoirs. The proposed...

The current situation with green gas emission requires the development of low carbon energy solutions. However, a significant part of the modern energy industry still relies on fossil fuels. To combine these two contradictory targets, we investigate a strategy based on a combination of CO2 sequestration with Enhanced Oil Recovery (EOR) in the...

In the modeling of fractured reservoirs, the spatial representation plays an important role to enclose the heterogeneities present in the subsurface. The reservoir flow response obtained from simulation in time is determined by the type of method and by the scale of the representation (fine or coarse). As a deterministic model cannot capture the...

Given the substantial growth of the shale industry over the last decade, understanding flow in confined spaces will play a primordial role in the future of the upstream petroleum sector. Most compositional simulators are designed for standard (unconfined) reservoirs. Additional physical phenomena occurring in confined spaces such as capillary...

Reservoir simulation is a broadly used tool in the oil and gas production industry. It can be used for production history matching, performance forecasting and field development. A common Enhanced Oil Recovery (EOR) method is the injection of miscible gases. With the injection of gas into an oil reservoir, the system has to be considered as...

Subsurface carbon dioxide (CO2) sequestration is a promising technology to reduce the CO2 emission into the atmosphere. After injection into subsurface formation, the carbon dioxide plume can migrate several kilometres until it is fully trapped. Four major mechanisms play an important role in trapping which include structural trapping, residual...

One of the methods of reducing the amount of CO2 in the air is CO2 sequestration by dissolving the gas underground in an aquifer. In practice,there will be impurity gases in the injected CO2 stream or in the aquifer, which influence the dissolution rate of the CO2 stream. This research aims at finding a method to evaluate and calculate this...

In-depth water diversion is a chemical EOR method that has been winning acceptance over the last years because of several reasons. One of them is the fact that sodium silicate, active component, is considered a green chemical. Moreover, this component has shown the ability to generate thermally activated plugs at far away distances from the...

In the recent years, geothermal technology has received substantial attention as an alternative source of energy. However, the lack of detailed information about subsurface formations of interest often introduces significant uncertainties to the technological and economic planning of geothermal projects. As the result, some important...

Acidisation is one of the oldest techniques for enhancing oil recovery, going back more than a 100 years ago. The accurate description of this physical and chemical phenomenon is not a straightforward task. The Darcy law, which is commonly used in continuum modelling at the macroscale, fails when the porosity approaches the unity due to a...

Under-sampling of the subsurface combined with scale differences in observations causes the estimation of geological parameters to be an ill-posed problem. As a result, only a subset of theoretically possible models can truly depict the reality. In reservoir modeling, we capture complexity and heterogeneity by representing the solution space...

To date no efforts were published to (numerically) compute the pressure transients following shut-in for a fracture that during pumping was propagating at an arbitrary, not necessarily constant velocity; and to use these computations to systematically understand the physics (type curves) of pressure decline after shut-in for both very rapidly...

In recent years, humanity became strongly dependent on the deep subsurface. It can be used as the energy source as well as the storage facility. At some stage, both listed applications require injection of fluid or gas into the subsurface porous media. Under certain conditions, it may provoke growth of hydraulic fractures. The appearance of...

Designing strategies for efficient oil production from reservoirs rely heavily on reservoir simulation studies, which in-turn is based on various nonlinear formulations. It is therefore very important to develop a robust simulation model that captures the flow of various components present in different phases and the associated thermodynamic and...
