Trends
- Wellbore microbial plugging and consequent lost of injectivity (clogging).
- Dispersion of components necessary to the target.
- Control of indigenous microbial activity.
- Mitigation of unwanted secondary activity due to competitive redox processes such as sulphate reduction, i.e. control of souring.
- Microbial paraffin removal.
- Microbial skin damage removal.
- Water floods, where continuous water phase enables the introduction of MEOR.
- Single-well stimulation, here the low cost makes MEOR the best choice.
- Selective plugging strategies.
- MEOR with ultramicrobes.
- Genetically engineered MEOR microorganisms able to survive, grow and produce metabolites at the expense of cheap nutrients and substrates.
- Application of extremophiles: halophiles, barophiles, and thermophiles.
- Artificial neural network modelling for describing in situ MEOR processes.
- Competition of exogenous microbes with indigenous micro flora, no understanding of microbial activity.

Famous quotes containing the word trends:
“Power-worship blurs political judgement because it leads, almost unavoidably, to the belief that present trends will continue. Whoever is winning at the moment will always seem to be invincible.”
—George Orwell (1903–1950)
“A point has been reached where the peoples of the Americas must take cognizance of growing ill-will, of marked trends toward aggression, of increasing armaments, of shortening tempers—a situation which has in it many of the elements that lead to the tragedy of general war.... Peace is threatened by those who seek selfish power.”
—Franklin D. Roosevelt (1882–1945)
“Thanks to recent trends in the theory of knowledge, history is now better aware of its own worth and unassailability than it formerly was. It is precisely in its inexact character, in the fact that it can never be normative and does not have to be, that its security lies.”
—Johan Huizinga (1872–1945)
