Injection Strategies

To develop improved alkali-surfactant flooding methods, several different injection strategies were tested for recovering heavy oils. Oil recovery was compared for four different injection strategies [641] ...

There are two main injection strategies for CE, electrokinetic and pressure. Each type of injection mode has its advantages and disadvantages. Depending on the application, the appropriate mode must be chosen. 

The development of an injection strategy requires consideration of many variables (Benoit et al. 2000). They include (1) an injection scheme, (2) where to inject and how deep,... 

The estimate of the fill time shows that a more detailed study of injection strategy and process parameters is necessary because it is difficult to reach an acceptable production economy with a fill time of about 1 h. An obvious action would be to choose a more efficient resin distribution method than a one-point inlet (e.g., peripheral injection or a multipoint injection). In addition, it would be worthwhile to try to lower the viscosity and increase the pressure.

This model was used (47) to evaluate the foam-injection strategy and concentration that resulted in the highest profit. The study was based on the discounted net profit (DNP) due to surfactant injection which was defined as... 

Reactant and energy injection strategy, as one-shut (batch), continuous pulsed injection, reversed flow, staged injection, and use of a membrane. 

Optimal CTA imaging is dependent on the concentration of intravascular iodine, which in turn is dependent on both choice of contrast and injection strategy. Nonionic CT contrast agents have been shown to be safe in an animal model of MCA stroke, without significant neuronal toxicity, even to already ischemic neurons [41, 42], There are several forms of nonionic contrast, with varying concentrations of iodine. The relationship between concentration and enhancement is demonstrated graphically in Fig. 4.6 [43,44].

Mixture stratification (or, in other words, the extent of premixing) is determined to some extent by injection strategies. In the next section, some of these strategies will be discussed. Note that LTC engines are still under development and so fuel delivery strategies are evolving. Other approaches, not discussed below, have been reported in the literature.

With the proper fault injection strategy, the verifier can check a wide range of faults sequence possibilities. For example, inject a fault and then remove it without status restoration in order to examine the system behaviour caused by entering and leaving of the fault. 

Su and co-workers have reported a simple, one pot, non-injection strategy for large scale synthesis of wurtzite CZTS nanocrystals.Typical...
