... approaches to define the screening criteria on dual-porosity reservoirs have been postulated; the evaluation of the matrix-fracture interaction still requires complex models for proper EOR selection. This paper offers a multidimensional approach to EOR selection in dual-porosity naturally fractured...

.../EOR projects. The technology implies the application of an inflow control device (ICD) or intelligent completion or a combination of both. Application of intelligent and ICD completions have been identified and evaluated by multiple operators for multiple fields under IOR/EOR in Malaysia. This paper...

..., steam quality >0.4, injection rate equals 300 m 3 /d. The predicted oil recovery increases from 5% for cold production to 18% for cyclic steam injection. In this paper we present the application and evaluation of the cyclic steam injection, which is a high quality steam injection...

... wells and so on, we have found out petrophysical changes in reservoirs after ASP, evaluated oil displacement efficiency of different locations, and systematically analyzed influcing factors on occurrence of displacement efficiency differences. The study results show that the oil displacing efficiency...

... Alkaline Polymer Surfactant (ASP) flooding is an Enhanced Oil Recovery (EOR) technique aiming to mobilise remaining and residual oil. Estimating the average oil saturation prior to and post ASP flooding is a recognised challenge, but is vital to the evaluation of an ASP pilot. The use of oil...

... Abstract The Loma Alta Sur (LAS) field is a multi-layer fluvial sandstone reservoir in the Neuquén Basin, Argentina. Reservoir heterogeneities and adverse mobility ratio (30 cp oil) led to an early water breakthrough short after water injection started. After the evaluation of different IOR/EOR...

... contamination and to minimize operation time. Through the analysis of the acquired logs, vertical contrast of preferential CO 2 injection, zonal oil saturation change, oil saturation change with time within single run, etc., were clearly identified. These observations played important roles in evaluating...

... Abstract As part of the development planning of an alternating water and gas injection scheme for Enchance Oil Recovery in the Bokor Field, a risk evaluation study was carried out to assess the likelihood of injection gas migration from the reservoir to the seabed. This hazard was identified...

... Abstract In mature fields, optimization of CO 2 flood and tertiary oil recovery demand accurate and consistent formation evaluation in producing wells. The complex well history—including near-wellbore (NWB) stimulation and recompletion for flood injection—often poses challenges...

...), screening evaluation began late 2009, identified Colloidal Dispersion Gel (CDG) as an optimum EOR method for the field. This paper summarizes Dina CDG project from the laboratory to the field evaluation. Laboratory studies include basic fluid/fluid evaluation, static adsorption, CDG formulations, slimtube...
