Alaska holds more than 68 billion barrels of proved oil reserves and more than 36.7 trillion cubic feet of proved natural gas reserves with some special conditions such as proximity to permafrost, making Alaskan petroleum reserves unique. The low temperature in shallow reservoirs prohibited hydrocarbons’ ideal maturation, thereby generating several heavy and viscous oil accumulations in this state. This also limits the enhanced oil recovery (EOR) options, leaving the thermal methods off the table to avoid permafrost thawing, which can cause wellbore collapse. Several solutions have been attempted for improving oil production from heavy and viscous oil in Alaska; however, they have not yielded the desired recovery, and ultimate recovery factors are still less than the global average. One solution identified as a better alternative is using CO2 as an injecting fluid, alternated by water or mixed with other injectants. This paper provides a comprehensive overview of all studies on using CO2 for enhanced oil recovery purposes in Alaska and highlights common and unique challenges this approach may face. The suitability of CO2-EOR methods in the Alaskan oil pools is examined, and a ranking of the oil pools with publicly available data is provided.

Chemical flooding is one of the major enhanced oil recovery (EOR) techniques particularly for reservoirs where thermal methods are not applicable, that chemical flooding may be polymer flooding, alkaline flooding, surfactant flooding, or a combination of them. The application of designing a chemical flooding program is strongly affected by the current economics, reservoir oil type, and crude oil price. In this project, mechanisms of different chemical methods will be discussed, and design chemical flooding program by using a laboratory scale and programming method. This project is mainly about making a design of surfactant flooding program, through choosing the optimum surfactant concentration. Also, economic study is very important in designing the program to know if the project is profitable or not to identify its efficiency, and choosing the better type of surfactant flooding in the reservoir. The results of this project proved that the surfactant has good effect on rock wettability to more water- wet, so increase the hydrocarbon recovery.

1D Model

Thermal methods of enhanced oil recovery and especially the in-situ combustion known to the efficient methods among the known enhanced oil recovery methods. In this method heat is added to the reservoir to reduce the oil viscosity. So, that it can be more efficiently driven to the producing well. However the experimental analysis of ISC to understand its operation is known to be expensive. Therefore we have developed a 1D model using STARS module of CMG where in we have Cartesian grid. To this we have given and given i, j, k values. Later porosity, Temperature and initial pressures are given. For setting the well we have used injector and producer. After checking errors we have validated the model. It is evident from the performance plots that the temperature along the core is a function of the gas injected and the oil saturation. However the as the temperature moves along the reservoir from injection well the oil saturation is observed to decrease in the vicinity of the well and start to build away from the injection well towards the production well. This is work provides a platform to understands the combustion propagation and its role in improving the oil recoveries

Innovative Methods

The production of oil and gas from hydrocarbon reservoirs with the aging of these reservoirs makes them consuming their natural production energy and become depleted. Then, conducting researches and investigations to use other energy resources to improve oil production becomes an urgent need. The article presents the generaldirections of methods for enhancing oil recovery and focuses on steam-thermal methods. Based on the classification of enhanced oil recovery methods, it has been shown that thermal methods (in particular, thermal steam) are the most favourable when applied in fields with a depth of about 1000 meters. The technology of cyclic steam injection is presented and the main stages of this process are indicated. Recommendations on the technology of steam-thermal treatment are given. For example, two oil fields have been selected to show the efficiency of the use of thermal steam treatment for reservoirs with high-viscosity oils.

Solar Resource

Solar steam generation for enhanced oil recovery has a significant potential at regions where, in addition to heavy oil reservoirs, solar resource is abundant. China ranks amongst the countries with greater heavy oil reserves. In addition, Western regions of China have a solar resource equivalent to that of places in which solar energy is being developed in a commercial scale. This paper addresses the technical feasibility of using concentrating solar collectors to produce the steam required in the recovery of heavy oil through thermal methods. Three locations have been selected for this study. In each location, three different reservoir injectivity scenarios have been taken into account: No injectivity limitation (as upper bound), partial limitation and full limitation (meaning that the injection rate cannot be greater than the design value for constant rate). In the first scenario, the surface model uses parabolic through collectors and direct steam generation. When injectivity is restricted, thermal storage becomes necessary in order to be able to inject the same amount of heat into the reservoir within the limits of the reservoir’s injectivity. Therefore, molten salts tower system with sensible storage is proposed as technology for the second scenario. In the third scenario, also parabolic through collectors are used but in this case, the solar system is coupled with conventional Once-Through Steam Generators (OTSGs) in a hybrid scheme (this approach represents the current state of the art).
