Formation Tester Interval Pressure Transient Test And Apparatus |
| 摘要 |
A methodology for IPTT (interval pressure transient testing) design which allows estimation of the reliability of the transient tests. A normally distributed random noise is superimposed on analytical pressure profile computed for a given formation, PVT, and gauge metrology. The IPTT success in a particular environment is estimated based on the theoretical pressure derivative and noise superimposed pressure derivative. This approach is repeated for a range of rock, fluid properties, and practical limits, for a successful IPTT. |

1. A method to obtain a reliability of an interval pressure transient test, comprising:
obtaining an analytical pressure profile for a given formation; generating a random noise profile; superimposing the random noise profile on the analytical pressure profile for the given formation; generating a derivative of the analytical pressure profile for the given formation; generating a noise superimposed pressure derivative from the superimposed random noise profile; and estimating the reliability of the interval pressure transient test based on the derivative of the analytical pressure profile and the noise superimposed pressure derivative. |
