The phrase "alternate injection" is correct and usable in written English.
It can be used in contexts where you are discussing different methods or options for administering something, often in medical or technical fields.
Example: "The doctor recommended an alternate injection method to reduce the patient's discomfort during the procedure."
Alternatives: "alternative injection" or "substitute injection".
After three cycles of WAG, when there was no more oil production, an ASP slug was injected into the core and then displaced by alternate injection of water and CO2.
Alternate injection of Fe(II) + As III) and S2− was conducted to simulate in situ As immobilization from real groundwater.
The enhancement in oil recovery was due to the formation of foam in the core plug by the alternate injection of surfactant solution and CO2 gas.
In addition, the oil recovery factor for water/gas alternate injection (WAG) strategy is higher than that of continuous low oxygen air flooding.
Alternate injection of Fe(II), O2-free water and S2− can realize Fe-sulfide coating onto quartz sands with minor changes in porosity.
The As III) immobilization mechanism during alternate injection of Fe(II) + As III) and S2− was significantly different from that of As III) uptake by Fe-sulfide coating.
Six lots of blank biological matrices were extracted each in triplicates and postspiked with the aqueous standard at the mid-QC level and compared with neat standards of the same concentration in alternate injections.
Intermittent hypoxia used alternate injections of nitrogen and air over multiple cycles.
Those randomized to the peginterferon beta-1a dosed every 4 weeks group received alternate injections of placebo and peginterferon beta-1a every 2 weeks.
In addition, compared with alternating injection, simultaneous injection does lower the injectivity for the conventional foam (Rossen et al. 1995) while this problem has been greatly mitigated with the novel foam (SIAP) even though the sweep efficiency is relatively poor.
(2) Alternating injection does improve the foam propagation and injectivity regardless of surfactant type.
