Paper Number: SPE-182721-MS
... formations, depletion-induced reservoir compaction results in serious damage and permanent deformation of rock formation. Cap plasticity models are crucial to achieve a more reliable prediction on the compaction of reservoirs with soft rocks. In this study, we develop a fully coupled and fully implicit...

Paper presented at the SPE Reservoir Simulation Symposium, February 18–20, 2013
Paper Number: SPE-163590-MS
... Abstract Performance prediction for diatomite reservoirs is very challenging because these reservoirs have a low permeability, contain fractures, and are very compactible. Therefore it has been suggested that reservoir simulation is not suitable for forecasting future hydrocarbon production...

... (upscaled) without actually being subjected to the same rigor of process or scrutiny. Compacting reservoirs often contain fine sand-shale sequences on sub-grid scale (compared to flow modeling grid) and are typically represented in simulators by the net-to-gross (NTG) concept, while being ignored...

... domains by means of the Mortar-FEM plus the above DD-Schemes. Several examples of coupling of elasticity and poroelasticity in the context of reservoir compaction and subsidence are presented. In order to facilitate the implementation of complex workflows, we have implemented an advanced Python wrapper...

..., and subsequently in February 1982, August 1985, October 1986, May 1990, October 1994, March 1997, July 2000, and May 2005. Geomechanical model Pressure depletion in a reservoir causes it to compact. In Roswinkel, reservoir compaction has been modeled using a simple coupling with effective pore...

... changes in the porosity field. During the depletion phase or the cold water injection of HP-HT reservoirs, the stress state in and around a reservoir can change dramatically. This process might result in rock movements such as compaction, induced fracturing, enhancement of natural fractures and/or fault...

Paper presented at the SPE Reservoir Simulation Symposium, February 14–17, 1999
Paper Number: SPE-51927-MS
... Abstract Coupled geomechanical and reservoir modeling is becoming feasible on a full field scale. This paper describes the advances of the coupled model described previously 1 , its extensions for modeling compaction and the application of the model in full field studies. The advances...

Paper Number: SPE-51920-MS
... simulation output (pore pressures) from a 10-year test case based on the Belridge Field in California drives the geomechanics simulation for the same time period. The high-porosity, low-permeability Belridge diatomite undergoes significant compaction including 6 feet of vertical displacement at the top...

... commonly used. Options to recalculate block permeabilities, transmissibilities, and thermal conductivities according to changes in porosity and thickness due to compaction are included. Results from a series of simulations using data of hypothetical reservoirs are presented; these show a strong dependence...
