METHOD OF GRAVITY ASSISTED MICROBIOLOGICALLY ENHANCED OIL RECOVERY BY IMPROVING THE DISTRIBUTION OF NUTRIENTS INTRODUCED INTO OIL PRODUCING ROCK FORMATIONS |
摘要 |
<p>A method of improving oil recovery includes the step of selecting an oil containing rock formation having geologic structures and well completions with vertical permeability that allow a structurally high water injection point. Through a series of analyses a nutrient water mixture is determined and injected at the injection point to stimulate resident microorganisms through gravity dispersion of nutrient materials. A period of limitation is allowed to permit changes in the size or hydrophobic properties of the microorganisms. Through interaction with the stimulated resident microorganisms, oil, trapped in a pore space, is freed to accumulate with upward gravity separation for production.</p> |
