Abstract
In the following paper a report of both surface and subsurface geology of the Montebello oil field is given. First a general survey of this area was made and then a geologic map with all field data plotted was prepared. Subsurface correlations were made by use of the electrical logs (Schlumberger) and the subsurface structure was studied. Also data from previous publications and from the core samples of the older drilled oil wells in this area was utilized in preparing a structure contour map. This area, because of its large oil fields, has been of economical importance for the last twenty years. Recently two new fields were brought in and it is estimated that these fields are going to make a new record for oil production in the state of California. One of these new fields is on the east and somewhat to the south of the old field and the second new field is located on the southwest corner of the old field. Both of those fields are of different horizones and much deeper than the older pool. The older field known as Montebello field is an anticline, with its axis running in an east and westerly direction. There is a major unconformity below this anticline beneath which appears the oil sands of the lower horizons of the newly discovered pools. The nature of rocks is highly complicated and shoreline deposits ore well recognized in this area. Most of these sediments are sandstones of different characters. These sandstones get coarser and grade into conglomerates from one side and chance to silt and at some instances to a thin layer of shale. There is a big fault in this area which cuts the upper most sediments and for which there are some surface evidences. It is shown (by use of Schlumberger methods) also that there exists another fault which cuts the axis of the new eastern field and of which there is no surface evidences.
