//// 6. Kőrösszegapáti. The structure Kőrösszegapáti represents an oblong well-developed elevation, the striking trend of which is in the southern part SW— NE, in the northern part WSW—ENE (Fig. 19). The seismic and gravimetric measurements coincide well and the wells proved the results in every respect (Fig. 20). The SE flank of the structure is steeper the NW flank (Fig. 21—22). The Pannonian transgressed on the crystalline basement rock on the SE flank. On the other hand, an outpinching Tortonian conglomerate deposit, which most probably passes into Sarmatian, is found on the NW flank (Fig. 22). Rich gas and weaker oil accumulations are found in these conglomerates. The well Körösszegapáti 1. encountered gas only; the well Körösszegapáti 3. w 7ent to water. The w Tell Körösszegapáti 5. which had been staked out above the edge water zone could not be completed because of the political events. 7. Kismarja. The structure of Kismarja represents also a very w rell-developed elevation of the basement of a more round shape with a SW — NE striking trend (Fig. 23). The highest point reaches up to approximately 2,950 ft, and the flanks are rather steep (Fig. 24). The seismic and gravimetric measurements, as well as the results of the wells, coincide very well. The wells Kismarja 1. and 2. both reached the crystalline basement rock. The Lower Pannonian clay beds pinch out toward the top, the same may be said of the weak Tortonian conglomerate deposits, which have been encountered in the well Kismarja 2. As neither gas nor oil traces were encountered in this conglomerate, it is not to be expected that in its southwestern continuation, where the thickness most probably increases, such accumulations could be expected (Fig. 25). VI. Technical Completion of Wells. Table IV shows the drilling outfits used; Figure 26 give a summary of the casing used. (a) Tótkomlós 1. Drilling time: 23 May 1941 to 4 August 1941. On 4 August 1941 the well encountered at a depth of 5,311.4 ft, strong gas shows, at
