Abstract:
The present invention utilise the phenomena of nutrient adsorption to enhance nutrient bioavailability and enhance methanogenesis efficiency. Thus methods for avoiding or reversing such adsorption or utilising the phenomena in a way favourable to promotion of methanogenesis in a formation, for example, through desorption of bound nutrients, or adsorption competing bacteria nutrients or methanogen toxicants, etc., are provided herein.

Claim (Index 1):
A method of developing a subterranean formation amendment regime to increase efficiency of stimulated biogenic methanogenesis of a carbonaceous feedstock in a subterranean formation, comprising the steps of:\n (a) analysing one or more components of the formation to determine a set of nutrient adsorption and/or desorption environmental characteristics associated with the formation environment in its native state, wherein the nutrients are one or more biostimulating nutrients which are adsorbable onto, and/or, desorbable from, the one or more components of the formation; (b) detecting a presence of one or more methanogenic microbes within the formation; (c) measuring a level of methane gas production occurring within the formation; (d) using information obtained from steps (a) to (c) to devise an optimised formation environment with respect to biostimulating nutrient adsorption and/or desorption that promotes optimal in-situ methanogenesis from the feedstock by the methanogenic microbes through modification of the adsorption and/or desorption environmental characteristics of the formation to enhance bioavailability of the one or more biostimulating nutrients; and (e) developing a formation environment amendment regime for application to the native formation environment to increase the methanogenesis efficiency by determining one or more adjustments required to the one or more components of the formation to substantially replicate in-situ the optimised formation environment with respect to biostimulating nutrient adsorption and/or desorption determined in step (d), whereby application of the amendment regime to the formation affects adsorption and/or desorption of the one or more biostimulating nutrients to increase methanogenesis efficiency.
