Methods Available
• | Ehlig-Economides and Joseph (1987) requires

| in individual zones and two rates. |
• | Methods were also developed by Kucuk et al. |
| 1986 (multi-rate analysis, early transient |
| state). Implication is bottomhole |
| measurements. |
• | Flow rate and pressure survey with depth for |
| each rate |
• | Similar concept presented by Nelson and |
