In China, CO2 EOR technology is mostly applied in small scale field test after water flooding.
The vaporisation of a liquid nitrogen pool spilled on concrete ground was investigated in small scale field experiments.
Small scale field and laboratory experiments, with a mixture of diesel and oil, and reservoirs ranging from 0.08 to 0.3 m, have been performed.
Phytoremdiation has been tested in small scale field trials (Murakami et al., 2009; Mandal et al., 2012; Deng et al., 2015), but its applicability to cleaning up large areas of contaminated paddy soils remains uncertain.
To make up for those shortcomings, the report called for a research program, including smaller scale field trials, whose goal "should be to improve understanding of the range of climate and other environmental effects of albedo modification, as well as understanding of unintended impacts".
We thus carried out a 2-year comparative study on yield performances and boll distribution patterns of Bt and non-Bt cotton in 20 small-scale fields around Makhathini Flats (KwaZulu Natal, South Africa).
It appears therefore that the small-scale fields do not follow a purely managed cultivation pattern.
Nevertheless, the report calls for more research and even small-scale field trials of the technology.
In Nigeria my own (admittedly small-scale) field research shows that 85% of workers hired by Chinese manufacturers are locals.
Laboratory and small-scale field observations have yielded fundamental insights into the causes of nitrate pollution.
Small-scale field studies have demonstrated treatment of Cd, Cr, Cu, Fe, Ni, Pb, NO3, PO4 and SO4.
