The gravity method was the first geophysical technique to be used in oil and gas exploration. Despite being eclipsed by seismology, it has continued to be an important and sometimes crucial constraint in a number of exploration areas. In oil explorat

On Talwani’s 'Errors in the total Bouguer reduction'
Autor: T. R. LaFehr
Publikováno v: GEOPHYSICS. 63:1131-1136
Talwani (1998) shows that the differences between the values for the Bullard B correction published in Swick (1942) and those I calculated (LaFehr, 1991b) owe their existence to the fact that we now use a different gravitational constant. I am gratef

Errors in the total Bouguer reduction
Autor: T. R. LaFehr, Manik Talwani
Publikováno v: GEOPHYSICS. 63:1125-1130
This short note discusses various errors in the Bouguer reduction that have been discussed recently in the literature. It also discusses two other errors arising out of the “indirect effect” and the uncertainty in the value of the universal const

Standardization in gravity reduction
Autor: T. R. LaFehr
Publikováno v: GEOPHYSICS. 56:1170-1178
Gravity reduction standards are needed to improve anomaly quality for interpretation and to facilitate the joining together of different data sets. To the extent possible, data reduction should be quantitative, objective, and comprehensive, leaving a

An exact solution for the gravity curvature (Bullard B) correction
Autor: T. R. LaFehr
Publikováno v: GEOPHYSICS. 56:1179-1184
The complete Bouguer reduction includes, in addition to the simple Bouguer slab correction (Bullard A), both curvature (Bullard B) and terrain (Bullard C) corrections. A new closed‐form formula for the curvature correction is derived for which the

Improvement of 3D seismic processing parameters using an old dog and new tricks
Autor: T. R. LaFehr, J. E. Brain, T. R. Horscroft
Publikováno v: 56th EAEG Meeting.
Many of the new and extremely promising seismic processing techniques have an inherent structural model as the starting premise. Tuning of this model is then performed and used as a refinement on the seismic processing parameter selection. Other inde
