Degradable polymers for wellbore fluids and processes
摘要:
A viscosifying agent for wellbore fluids is described including a polymer polymerized using at least two pre-polymers “A” and “B”, the polymer being capable of essentially fully degrading into soluble fragments after the initiation of a breaking process.
