..., seawater, and surfactant solutions were utilized. The drainage process was performed systematically using a coreflooding system to establish initial water saturation by injecting heavy oil followed by crude oil and aging for two weeks. Afterward, all six cores were subjected to spontaneous imbibition using...

... requirements. A lot of research is happening to exploit this promising energy source. Geothermal energy is extracted by injecting a fluid stream and the fluid coming out of the reservoir is then used to run turbines to meet the power requirements. This paper highlights the study on the pressure transient...

... Abstract Chemical injection has been emerged to be one of the processes that can improve oil recovery from major Malaysian offshore oilfield which is currently under waterflooding. Alkali-surfactant (AS) process was identified to be an optimized chemical system for this application...

... wells have been applied in Middle East universally. However, with complex geological conditions including thief zone, aquifer and heavy oil, there are diverse production/injection performances for horizontal wells. Therefore, history matching is a tough job for reservoirs with horizontal wells. Pressure...

... in February 2016 with a reservoir pressure of ~1500 psi. Water compatibility tests and core flow tests were conducted. These tests showed favorable results that formation rock was compatible with injection water and that does not contain swelling clays like smectite. Injection in this well was commissioned...

... While the pore-scale ranking looks at recovery improvement, compatibility instead looks at potential show-stoppers due to each EOR method's current reservoir conditions. In this section, issues such as chemical compatibility with formation temperature, salinity, and injectivity (directly related...

... Abstract A compositional dynamic simulation model is fully implicitly integrated with a gas injection surface network model, to study the effects of CO2 injection into a depleted gas field. Multiple prediction scenarios are evaluated, under uncertainty, to reduce risk and improve decision...

... in a carbonate reservoir of the Middle East, the results show that the model and software accurately describes the CO 2 -EOR seepage mechanism and CO 2 miscible displacement process. It effectively predicts the effect of CO 2 injection on EOR and the storage potential after CO 2 flooding. It can provide...

... The study shows that the main reasons behind the low oil recovery of the unit is the inefficiency of the gas injection (percolation effects to upper units) especially in the southern area which is of relatively good quality compared to the northern area. Accordingly, the new redevelopment plan...

... to CO 2 being dissolved in the formation ( Zhang and Song, 2014 ). When injected into deep formations, CO 2 mineral trapping can also occur due to geochemical reactions (i.e., dissolution/precipitation) leading to permanent and secure CO 2 storage ( Xu et al., 2003 ; Iglauer and Nakajima, 2011...

... The current research mainly considers the effect of steam injected into the formation on rocks and minerals, but does not consider the effect on cores with different clay contents. In order to obtain the change of pore throat structure of cores with different clay content after steam flooding...

... shallow, relatively less depleted zone show improvement in Es. Implementing a regular 5-spot pattern water flood instead of random spot water injection in a major shallow zone improves Ed and Es. Lastly, Alkaline Surfactant Polymer (ASP) flooding improves Ep. A detailed roadmap was generated for each...

... of this paper. Injection or production of fluid in naturally fractured reservoirs (NFRs) typically causes slippage, opening, and fracture compliance effects that depend on elevation or decrease of fluid pressure in the rock. In this work, we solve equations of fluid transport in a rock with a high density...

... The geologic and reservoir simulation model described in this study was constructed to generate multiple CO2 injections simulations in support of a Class VI injection permit application. This model was used in the preliminary evaluation of the depleted gas reservoir for CCS applications...

... could be improved but also the experimental cost could be minimized. The AOP measurements showed clear potential risks associated with CO 2 injection. Subsequently, the numerical model analysis was conducted with Cubic-Plus-Association (CPA) EoS model to identify the risk area during CO 2 injection...

... Abstract We present an efficient compositional framework for simulation of CO2 storage in saline aquifers with complex geological geometries during a lifelong injection and migration process. To improve the computation efficiency, the general framework considers the essential hydrodynamic...

... Abstract The objective of this work is the prediction of water salinity evolution trend for Mexico Area-1 development that foresees the injection of a mixture of seawater and produced water from the six different reservoirs connected to the same FPSO. Prediction of salinity trend evolution...

... al, 1989 ). However, in some cases, for example, for light oil, when modeling the effects of gas injection, for gas condensate fields, the use of black-oil models gives unsatisfactory results. Field development simulation, accompanied by such processes, requires the use of compositional models...

... Voidage Replacement Ratio (VRR) can be defined as the ratio between the total fluid injection in reservoir barrels and the total fluid production in reservoir barrels. VRR is used as a key indicator to achieve the required reservoir pressure, particularly when the wells are not equipped...

... Abstract As means of primary and secondary recovery, the fractured reservoirs with strong aquifer can be developed either by water injection or by utilizing the natural energy of the aquifer itself. High permeability contrast between fracture and matrix blocks and preferably mixed to oil-wet...
