The IPSM model links sixteen reservoir models with varying...

.... The developed oil reservoirs have a total of more than three hundreds development wells. The reservoir types are diverse, the relationship among multiphase fluids is complex, and the development methods are different. The reduction of the daily production will inevitably require a comprehensive strategy...

The upper gas reservoir and lower oil reservoir are in communication across a major fault in the crest area...

... group of applicable analogs. Abstract A countrywide benchmarking of ultimate recovery factor (URF) for oil reservoirs in Kuwait is presented in this study. The results of this study have been useful to support identification of long-term opportunities and have influenced the creation...

..., material balance techniques are used for two applications: (1) estimating the hydrocarbon in place and (2) forecasting production. As summarized by Ahmed (2010) , the performance forecast is usually performed for oil reservoirs using one of the techniques by Tracy, Muskat, and Tarner (1944) . The three...

... that the secondary LSW injection was more efficient than the tertiary LSW injection, especially in the acid-enriched oil reservoir. In summary, the total acid number (TAN) and the recovery mode appear to be the key successful factors for LSW in our carbonate system. gas injection method brine composition...

...%, the utilization factor is 4.35 t/t oil, compared with 1.3% recovery factor of depletion mode, by 10 years CO 2 periodic injection, recovery factor is enhanced by 3.76%. It is a big challenge to effectively develop the normal pressure continental deposit tight oil reservoir. In China reserves of tight reservoir...

... for the injected gas to become miscible with the in-situ oil at the beginning, especially for light and medium oil reservoirs. This process results in mixing of the gas with oil and hence the development of a single-phase flow with lower viscosity and density than the shale oil by itself. The development...

..., will then pinpoint the best locations to initiate pilot testing; this is outside the scope of the present paper. Ongoing or planned water flooding naturally opens up for considering WAG and water-based EOR methods. Abstract Many of the oil reservoirs in ADNOC’s portfolio have been producing for decades...

... is to compare the production performance of volatile oil reservoirs, generated from a commercial compositional simulator, by using simple decline models used in the industry. Fluids with different initial gas to oil ratio (GOR), due to different fluid composition, was simulated for a period of 30 years. Oil...

... Abstract Reservoir-A is a tight oil reservoir (<1 mD) with four subzones. Production from existing wells in this reservoir has been low due to the reservoir tightness (< 500 BPD), dual phases injection program is implemented to support the wells productivity and to increase the overall...

... Abstract Superheated steam has a smaller density and a larger specific volume than conventional saturated steam, and has a stronger override effect in heavy oil reservoir. As most of heavy oil reservoirs have strong heterogeneity because of high porosity and permeability. Therefore, the steam...
