Enhanced Oil Recovery in Fractured Reservoirs

Characterization of Fractured Reservoirs

Reliable, predictive models to optimize carbonate reservoir performance

Characterization of Liquid Bridge in Gas/Oil Gravity Drainage in Fractured Reservoirs

Gravity drainage is the main mechanism which controls the oil recovery from fractured reservoirs in both gas-cap drive and gas injection processes. The liquid bridge formed between two adjacent matrix blocks is responsible for capillary continuity phenomenon. The accurate determination of gas-liquid interface profile of liquid bridge is crucial to predict fracture capillary pressure precisely. ...

Redeveloping Mature Fractured Carbonate Reservoirs

Naturally fractured carbonate reservoirs (NFCRs) comprise the majority of the oil and gas reservoirs around the Persian Gulf.  Many of these reservoirs have a long history of exploitation, but vast amounts of oil remain in place.  A major redevelopment process for light oil based NFRs will likely be the use of horizontal wells combined with gravity drainage at constant pressure based on voidage...

Sensitivity Analysis of Cumulative Oil Production and Production Rate on Block Heights and Capillary Continuity for an Iranian Carbonated Fractured Reservoir

Block heights and capillary continuity between matrix blocks play paramount role in the sensitivity analysis and therefore the history matching of cumulative oil production and production rate of carbonated fractured reservoirs. In this study, the influence of these parameters upon cumulative production and recovery factor of an Iranian fractured reservoir were studied by the usage of a sim...

Application of Decline Analysis in Fractured Reservoirs, Field Case Studies

Decline curve analysis has some advantages over transient well test analysis in which it is not required to shut-in the well and also wellbore storage effects do not exist. Few studies have been done on decline curve analysis of naturally fractured reservoirs but there are even some limitations with available models. On the other hand well test could be expensive and in some operational conditi...
