... infrastructure, and investigates both existing and future opportunities. The concept of turning the reservoir heat from existing hydrocarbon fields into power is attracting much attention within both the oil and gas, and geothermal industries. Against a backdrop of the need to reduce production emissions...

... to the uncertainties in the area regarding pressure compartmentalization and hydraulic connection between regions, an early qualitative estimation for oil viscosities is important to reservoir characterization and drainage strategy. Abstract Peregrino is a heavy oil field in the Campos basin offshore Brazil...

..., particularly when stimulation techniques are available. However, no PVT samples have been obtained from Formation 1-A in the past wells. Simply assuming that the reservoir gas composition from the main producing reservoir zones applies to Formation 1-A can be risky, especially for low permeability zones...

...Background There are several depleted gas reservoirs in central Luconia field that could potentially be converted into CO 2 storage sites at the end of its producing life. The Central Luconia sedimentary basin is located in a seismic-free zone with limited faults and consists of shale...

... 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...

... 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...

... in the reservoir, but it was likely not due to diffusion and lateral gas spreading since even helium does not exhibit diffusive leakage in underground storage ( Panfilov 2010 ). CO 2 decomposition takes place in underground hydrogen storage as a result of microbial activities. Natural methane production...

... 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 three-dimensional r - θ - z single-phase-gas fully-implicit finite...

... The Tornado Field lies at the center of the Typhoon Minibasin (aka Phoenix). The Tornado structure is a salt-cored pop-up feature trending NE-SW. The Tornado B-6 reservoir discovery was made in 2016 in the Green Canyon area of the Central Gulf of Mexico by Talos Energy in a water depth of 2,750...

... 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...

... in the rock formation. If it is stored as a gas, or critical fluid, then the seal must be at the top of the reservoir; however, if it is stored in solution, the seal must be at the bottom of the reservoir. In practice, the storage mechanism is a combination of both. Injecting CO 2 into a geological formation...

... 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...

... method ( Chen et al., 1999 ) can be used to calculate the wetting and non-wetting reservoir relative permeability curves ( Li and Horne, 2006 ). Each AFRM requires a random number seed from which the AFRM creation process begins. This seed could be viewed as a key to the structure of the data volume...

...Field History and Reservoir Summary Abstract Recently two multilateral horizontal wells have been completed offshore using dedicated multistage hydraulic fracturing completions. The first well, located in the Central North Sea (referred to as ML-CNS), was stimulated using acid fracturing...
