Frequency Modulation of 0S2-D

Authors: Herbert Weidner
Comments: 5 Pages.

Precision measurements of the 0S2 quintet after the 2004-12-26 earthquake show that the spectral line near 313.8 µHz is frequency modulated with a remarkably large frequency deviation of 0.15 µHz. By proper choice of the integration length, the center frequency can be determined with high precision.

Frequency Modulation of 0S2-C

Authors: Herbert Weidner
Comments: 4 Pages.

Precision measurements of the 0S2 quintet after the 2004-12-26 earthquake show that the middle spectral line near 309.3 µHz is frequency modulated. The strongest modulation frequencies are phase-locked and depend on the geographic location. By proper choice of the integration length the center frequency can be determined with high precision.

Frequency Modulation of 0S2-A

Authors: Herbert Weidner
Comments: 4 Pages.

Precision measurements of the 0S2 quintet after the 2004-12-26 earthquake show that the lowest spectral line near 299.9 µHz is frequency modulated. The different modulation frequencies are phase-locked and depend on the geographic location. By proper choice of the integration length the center frequency can be determined with high precision.

Frequency Modulation of 0S2-E

Authors: Herbert Weidner
Comments: 5 Pages.

Precision measurements of the 0S2 quintet after the 2004-12-26 earthquake show that the highest spectral line near 318.4 µHz is frequency modulated. The different modulation frequencies are phase-locked and depend on the geographic location. By proper choice of the integration length the center frequency can be determined with high precision.

Implementation of Hagedorn-Brown Correlation Method in Single Fluid Volume Element (SFVE) Method for Predicting Flow of Geothermal Well based on Pressure-Depth and Temperature-Depth Measurement Data at Static Condition

Authors: Sparisoma Viridi, Windra Yusman, Sudjati Rachmat
Comments: 6 Pages. 4 figures, 10 tables

Advancement of implementation of single fluid volume element (SFVE) method in geothermal well application is presented in this work. Static pressure-depth profile is changed to dynamic one by implementing Hagedorn-Brown correlation method, which takes into account effects of acceleration, elevation, and friction in pressure depth calculation. Two-phase flow influences in mass flow, velocity, enthalpy, and density of flow are also considered.
