... studies of the carbon dioxide injection process, the Ivanić oil field was chosen as the first candidate for the application of this EOR method. In order to rebuild the Gamma 2/4 reservoir pressure before the pilot project, injection of water started in 2001. The WAG CO 2 process is being conducted...

... in Kuala Lumpur, Malaysia. Abstract Zaloni Barail Second Sand (Well 27 Block) reservoir in Zaloni oilfield was discovered in 1957. For pressure maintenance, peripheral water injection was initiated by injecting water into the acquifer in 1973. Polymer flood project was undertaken in this reservoir...

...) reservoir. After bacteria injection, 44 among the 60 huff and puff wells shows a significant oil production response—the accumulative oil increment reaches 6012 tons and the input-output ratio amounts to 1: 6. The Microbial enhanced waterflood test carried out in June 2004 also provides a satisfying result...

... Abstract Understanding and predicting multiple fracture propagation behaviour whilst injecting water in the layered reservoir of Field A, offshore Nigeria, presents several major challenges. The water flood efficiency will be affected by the behaviour of each independent fracture during...

... Abstract Due to the multiplicity of injection and production wells in waterflooded oilfields, tracer studies may require the use of several tracers for the water phase. Tritiated water is usually the radiotracer choice, but other tracers must be available. Is not a novel radiotracer but is has...

... Abstract Carbon Dioxide (CO 2 ) foam has been widely studied in connection with its application in EOR. This paper reports an experimental study concerning CO 2 foam propagation in a surfactant saturated Bentheim sandstone core and the subsequent liquid injection with the aid of X-ray Computed...

... Abstract The Ekofisk fractured chalk reservoir located in the North Sea south-west of Norway has been exploited successfully for more than three decades, largely due to injection of sea water. In a study concluded in 2004, air injection was evaluated as a method for additional hydrocarbon...

... technologies have been required to economically develop Canada's complex and varying oil fields. Various existing in-situ technologies such as hot water injection, steam flooding, cyclic steaming and combustion processes have been successfully applied in Venezuela and California. Most recently, advances made...

... experiments were performed using actual crude oil injected into actual reservoir rock samples of almost 23 cm length and 10 cm diameter. These samples were saturated at initial-oil-in-place condition and then subjected to water and/or CO 2 floodings. The minimum miscibility pressure (MMP) was calculated...

...Conclusions Optimization opportunities discussed here that may be applicable in other blowdowns are: Replace sales gas injection with raw gas injection sourced from a neighboring pool that is already in depletion in order to bypass plant constraints and increase sales. Look for ways...

... strategy, the production will stay on plateau for only 3 years. This is mainly due to the rapidly falling reservoir pressure. The remedial plan is to initiate a full field water injection project to maintain reservoir pressure. The primary objective of this project was to extend production plateau as long...

... Abstract This paper presents results of a comprehensive study to improve our understanding of High Mobility Ratio Water Flood (HMRWF) and to improve its performance prediction. Published data on heavy oil water injection field projects are limited. Several successful HMRWF projects have been...

In this study, we present gas injection program in West Java to obtain better recovery of the mature field/brownfield. The gas injection program include natural gas such as ethane, propane and CO 2 flooding...

... Abstract Steam injection EOR began in California forty years ago, and has been highly successful. As a consequence, California's thermal recovery operations represent a leading source of EOR production in the world. The understanding of most early thermal recovery operators was limited...

... Abstract Fractured injection is not new to the oil and gas industry, and occurs unintentionally in most water injection schemes. However, deliberate fractured water injection is usually not evaluated upfront in order to derive optimal cost and recovery, and open-up opportunities for further...

... Abstract During a half-year field test a novel method was applied for water injection during waterflooding in a weakly consolidated, heavy oil reservoir (90–120 cP). The injection has been combined with a hydraulic pulsing tool downhole in the injection well to provide additional dynamic...
