Seismic 4 289 depth below the northern part of the lake whereas they were discernibility on seismic sections and distinct velocity characteristics not detected in the south. There is also a difference along the relative to the surrounding sequences. These results, together with the bathymetric localized thickness variations of basalt and carbonate, but map, show a similar picture as in the Dead Sea, i.e., a long elastic units also show gradual velocity variations with narrow depression, whose floor tilts to the south and east, significant effects on regional time-to-depth conversion. Statistical being filled with sediment in the oldest, southern portion. In addition, the southern part well-derived velocity information provided more accurate of the graben (based on new seismic reflection data to be velocity maps.

The Dogger high is an uplifted block within this Central graben. Normal faulting along the graben margins was active during Triassic and late Jurassic. By late Cretaceous time differential subsidence had ceased and chalky limestones blanketed Synthetic Sonic Log Study of the Dan s4.1 both basins and highs. Sea subsided as a single basin. Dan field is located in the southwestern portion of the R. C. Mummery, Teknica Resource Development, Canada Danish North Sea.

The discovery well for the Dan field, seismic reflection traces by a digital computer program, The Dansk Nordsb M-1X well was drilled in May 1971 and basic concept is simple; a reversal of the procedure used to encountered a 230 m hydrocarbon column in the Danian compute synthetic seismograms from sonic logs. This process effectively transforms seismic information The stratigraphy revealed by the M-1X discovery well into the geologic domain. Vertical reflection time is converted consists of 580 m of Upper Miocene to recent sand and clay, to geologic depth, and reflection amplitude yields rock 1185 m of Lower Paleocene to Middle Miocene clay and transit time expressed in psecifoot. Transit time values were contoured and colored based on a standard stratigraphic color scheme. Rock units can be mapped, rather than the boundaries between them.

Spector, A., and Grant, F. S., 1970, Statistical models for interpret ing aeromagnetic data: Geophysics. A detailed geophysical investigation of the exposed Precambrian shield area of northeastern Alberta is currently northeastern Alberta. This information also aids in the study underway. The scope of this study includes an examination of variations in rock type and structure in the map area. of the interrelationships amongst a number of geophysical, Densities and susceptibilities of over 600 standard samples geochemical, and geologic parameters available in a variety from the exposed shield in northeastern Alberta were measured of existing data bases incorporating data from both field and by the Research Council of Alberta. Computer systems are used for storage, samples were chosen from many thousands of possible manipulation, and numerical analysis of the quantitative samples to be representative of local geology. It is anticipated that integration of these diverse data The distribution of density for all the standard samples is will lead not only to a better understanding of the geologic of interest.

On a statewide basis, elastic reservoirs gave grouping of reservoirs into families or "plays" of similar up 41 percent of the in-place oil; carbonate pools produced geology and common engineering and production attributes.

Seismic 23 589 seismic profiles recorded in deviated wells or with a variety recorded in a 3180 ft deep cased borehole (Enix 1) at Arco of source locations. Through modeling, the geometry of a Oil and Gas Co's geophysical test site in Hopkins County VSP can be designed to illuminate specific depth and otTset near Sulphur Springs, Texas. Encountered in this well are ranges. Variable source offsets can be used to cover either a Late Cretaceous shaly marls and silty clays. Furthermore, (Pecan Gap chalk) and calcareous quartz sand (Nacatoch multiple offset VSPs recorded with repeated shots from sand) deposited in shallow waters.
