Enhanced Oil Recovery Patents – 2018/2019 CO2 Injection

Carbon Dioxide injection has been used effectively for enhanced oil recovery from reservoirs, since at high pressures it forms a miscible mixture with oil, increasing the volume of the oil, and allowing it to dislodge additional material from the rock as it pushes through the formation.[1]  CO2 injection is often used in a process known as water alternated with gas (WAG), where the gas and water are alternately injected into the well, thereby mitigating the tendency of the lower density gas to migrate to the top of the reservoir and bypass other sections.[2]  Interest in CO2 injection continues, not simply in conventional oil reservoirs, but in unconventional reservoirs as well.[3]  Not surprisingly, aspects of CO2 injection find their way into patent claims.

If a trade secret is misappropriated by another, the owner may be entitled to damages, an injunction preventing further use or disclosure of the trade secret, and in some cases the recovery of attorneys’ fees.

Rising Carbon Dioxide Levels: Capture Methods & Patent Trends

Recent data from NOAA, the National Oceanic and Atmospheric Administration, indicates that current atmospheric carbon dioxide (CO2) levels are at 409 ppm as of October 2018. This is a 36% increase from the highest historical CO2 level,1 and is increasingly being attributed to human activity, namely fossil fuel combustion in power generation, […]
