Drilling packers are used in drilling operations to isolate certain zones in the well, control pressure, and increase drilling efficiency.
| GVF Range | Measurements | Uncertainty |
| 0~95% | WLR | 2% Abs. |
| 95~100% | WVF (water volume fraction) | 0.5% Abs. |
The production packer is designed to seal the annulus between the tubing and casing in production wells, helping to control fluid flow and improve oil and gas production efficiency.
