Latest Patents

Among his latest patents, two stand out for their innovative methodologies:

1. **Method for Treating Formations to Plug Flow** - This patent describes a creative method for plugging a zone within a subterranean formation to block unwanted fluid flow. Yeh's approach involves injecting a specific plugging solution that comprises an allyl monomer combined with an initiator. This solution, when subjected to elevated temperatures, hardens and forms a solid that effectively halts fluid passage. The allyl monomer choices include various diallyl esters, while the initiator typically consists of peroxy or azo compounds. Additionally, Yeh often incorporates diluents and coupling agents to enhance the effectiveness of the solution.

2. **Method for Consolidating a Subterranean Formation** - This patent details a procedure for consolidating subterranean formations, aimed at controlling the production of particulates. Similar to his plugging method, a specific consolidating solution, which includes an allyl monomer and initiator, is injected into the formation and allowed to set at elevated temperatures to create a consolidated mass. This patent further contributes to the efficiency and reliability of underground material management.
