Faults are so irregular and numerous in some fields that they become important factors in choosing well sites.

Such a sketch is valuable to the man who wants to know why oil is not found in certain localities. Wells at 1 would and did prove barren, while those toward the right were productive. Fig. 60.--Illustrates how the upthrow side of a fault acts as an anticline; the downthrow side, as a syncline. Again, in Fig. 60, there is a normal fault, showing the influence of such a fault on the oil strata. In this case the upthrow side of the fault on the west acts as an anticline, the down Fig. 61.--Illustrates how normal faulting may leave barren spaces. throw side, as a syncline. Wells 1 and 3 obtained oil; 2 and 4 did not. In Fig. 61 a fault is shown that illustrates how a drill hole might pass between productive oil strata and fail to strike oil in commercial quantities. The shale on the hanging-wall side abuts against the oil sands on the footwall side, and confines the oil to the sands below. Faults do not necessarily affect oil formations adversely, as shown in Figs. 27 and 296, Chapter IV. Careful study will show that in many cases faults are beneficial rather than detrimental. Minor Folds.--Minor folds have a very decided effect in some regions. Fig. 62 shows a number of minor folds on the flank of a monocline. These folds must be taken into consideration in drilling. Thus wells placed at various points, as at 1, 3, and 5, would strike oil and gas at much less depths than the major slope indicates. In such cases, too, one might strike wate...
