... Abstract Reservoir fluid estimation for exploration prospects can be random and of large uncertainties. Typically, the reservoir fluid estimation in a prospect can be derived from a geochemical basin model or seismic data interpretation with regional knowledge. An analog reservoir fluid sample...

... with pressure, non-Darcy flow, position of active (flowing) and observation probes, mechanical skin and radius of skin (or invaded) zone, and reservoir heterogeneity in the vertical direction. A three-dimensional r - θ - z single-phase-gas fully-implicit finite-difference model for a limited-entry vertical...

... Abstract The composition of natural gas and crude oils specifies their calorific and commercial value. To determine required processing steps for intermediate and end products of the reservoir fluid and to define the layout of production facilities, an accurate fluid analysis is vital...

... Abstract A depleted gas reservoir in Central Luconia field, located offshore Sarawak, was evaluated for future carbon dioxide (CO 2 ) storage. This carbonate reservoir has experienced seafloor subsidence during producing life. When coupled dynamic-geomechanics model was history matched...

... Abstract The offshore Captain Field was discovered in 1977 in the UK sector of the North Sea, it was brought online in 1997 and initially developed using field-wide waterflood using long horizontal wells and artificial lift with produced water re-injection. The reservoirs are large...

...: A subsurface screening exercise was completed, allowing geothermal resources to be identified and classified. The proposed workflow is based on a staged approach starting with the subsurface Geothermal Resource Assessment & Development Evaluation (GRADE). This involved a primary reservoir secreening...

... evaluated. Based on these, the paper assesses when the different effects are significant, in which brine tracking and temperature modelling are required. In addition, it provides insights about reservoir applications involving CO2. The majority of the studies in the literature about the effects of salinity...

.... Any changes in the viscosity in the reservoirs can lead to a large difference in oil recovery. Therefore, updating the viscosity distribution in the reservoirs along with the development drilling is important. Different methods can acquire reservoir oil viscosity, including downhole logging...

... in subsurface formation has become a viable option in recent years as more hydrocarbon reservoirs are depleted. A review of the literature revealed that there are limited modelling efforts for underground hydrogen storage in depleted gas reservoirs owing to a lack of field implementation for calibration...

... didn't communicate with the underlying Tor formation, which would reduce the recovery from both reservoirs. An alternative completion was sought that would enhance reservoir contact, while protecting reserves. Halfdan is a laterally extensive field and comprises a high porosity (25% - 35%), low...

... uk government reservoir blue hydrogen Introduction The UK is ideally placed geographically, technically, financially and politically to be a global low carbon centre, spanning both green and blue hydrogen production. We have an abundance of all the raw materials needed for low carbon...

... Abstract Waterflooding in deepwater reservoirs typically involves injecting seawater or produced water from the surface via pumps into injection wells. This technique is often cost-prohibitive for many reservoirs and poses significant mechanical/operational risks. This paper discusses how one...

... in the Black Sea (referred to as ML-BKS), was stimulated using proppant fracturing. This paper presents the different drivers, challenges and lessons learned for each well while emphasizing the well construction and stimulation methodologies developed for the different reservoirs and field characteristics...

... Abstract Following the significant reservoir depletion on Elgin / Franklin fields since 2007, drilling infill wells was considered to not only be high cost but also carry a high probability of failure to reach the well objective. The recent campaign on the Elgin field, one of the most heavily...

... Abstract Reservoir management for an economically successful chemical EOR project involves maintaining high injectivity to improve processing rates. In the Captain Field, horizontal injection wells offshore have been stimulated with surfactant-polymer fluids to reduce surrounding oil...

... Abstract New reservoirs are increasingly more heterogeneous and more anisotropic. Unfortunately, conventional reservoir modelling has a resolution of only about 50 m, which means it cannot be used to model heterogeneous and anisotropic reservoirs effectively when such reservoirs exhibit...

... Abstract In a deepwater environment, production fluid conditions have to satisfy complex requirements to flow smoothly to the production facilities on the FPSO. Flow assurance specialists work at turning these constraints into operating guidelines. This allows to close the gap between reservoir...

... Abstract Shallow oil reservoirs, commonly associated with heavy oil, require massive completion programs. The reason for these huge completion programs is due to the need for larger hole sizes compared with standard borehole developments. The commercial feasibility of these developments relies...
