Abstract Scope |
Dissolvable tools have been used more in unconventional oil and gas operations in recent years. Currently, more and more wells in Southwest of China quires high temperature (HT) dissolvable plug. The HT dissolvable plug needs to hold pressure in water at 150°C for 24 hours. On the other hand, the dissolvable plug needs to be dissolved in 1% KCl at 95°C in less than 15 days. These requirements put big challenges on dissolvable rubber materials. To meet the industrial challenges, several special coatings were developed to delay the dissolution time of the HT dissolvable rubbers. Two coatings for dissolvable rubbers delayed the dissolution time from 16 hour to 14 days. Two dissolvable plugs with coating B coated dissolvable rubber element passed the testing requirements. Based on our knowledge, this is the first time in the industry a HT dissolvable plug passed the requirements. |
