The pilot injections are a means to study the behavior of the recovery in situ sampling of the site. The behavior of the injection can be obtained at to get the performance you expect from a larger scale operations.
Limitations of a proposed water injection in oil wells:
* With small pilot increases the probability of locating in a non-representative of the site.
* The effects of a damaged well be more pronounced than a small number of wells.
* The loss of oil migration can result in an estimated recovery lower than what could be achieved with an injection on a larger scale.
* The injected water may be lost outside the pilot area, indicating higher water needs.
Clearly the importance of placing the pilot in a representative portion of the site.
The net thickness and So, are the most important variables. Net pay is available from cores or logs.
A damaged injector or a well located in a less permeable injection may produce lower costs. In an unbalanced arrangement produces injection. A damaged production well has a critical effect their results are likely to lower recoveries and higher oil migration
Information can be obtained from a Pilot Project Water Injection:
* At the beginning the main objective is to determine whether it could form an oil bank or an area of greater saturation.
* Information on water injectivity.
* Water injection is a proven process for oil recovery
* It is not always satisfactory and economically.
* There is a sound basis for the design of the water injection projects.
* The prediction methods have reached a high degree of refinement.
* We have at our disposal techniques for a good evaluation of the engineering of water injection.
