Synthetic polymer based fluid loss pill |
| abstract |
The compositions described herein may include an aqueous fluid, a crosslinked polyvinylpyrrolidone (PVP), and a betaine-based polymer. The methods described herein may include pumping a selected quantity of a fluid-loss pill into a formation, the fluid-loss pill including a crosslinked PVP and a betaine-based polymer and the betaine-based polymer being a copolymer of 2-(methacryloxy)ethyl)dimethyl-(3-sulfopropyl )ammonium and polyacrylamide and the betaine-based polymer has a 2-(methacryloxy)ethyl)dimethyl-(3-sulfopropyl)ammonium content in the range of from about 8% to about 12%. |
