| 摘要 |
<p>The present invention relates to the development of aptamers which exhibit an affinity for, or which adhere or bind to, hydrocarbons adsorbed, bound or otherwise associated to/with a surface. The aptamers for use in this invention are capable of affecting the release of the hydrocarbon they bind, from said surface. Aptamers of this type are particularly useful in, for example, processes used to recover hydrocarbons from reservoirs or hydrocarbon-bearing rock formations where, even after primary extraction, a large quantity of residual hydrocarbon can remain adsorbed and/or bound to surfaces of the reservoir or formation. This aptamer based technology may be used in isolation or together with existing hydrocarbon recovery processes to further reduce residual hydrocarbon saturation and improve hydrocarbon production.</p> |
