None of the wells is dist antmore than 200 or 300 feet from the plane of fracture, while one or twoare especially close to it, appearing, indeed, to have been sunk incrushed rock of the Modelo formation; however, in view of the uncer-tainty as to the dip of the fault plane it may be that they pass at slightdepth from the fragmental Modelo into the more solid strata of theolder formations north of the fault. The maximum depth attained is a little over 1,000 feet. The wellsare all small, 12 barrels per day being the largest individual yield atthe present time. The gravity of the oil varies somewhat from well towell, but the average is approximately 19° B. The color of the oil isgreen. The only flowing wells are those of the Ojai Company, whichlie west of the others, with their collars at a considerably lower eleva-tion; they are also very shallow and are, moreover, located directlyin the line of seepage of the region.
