Hello! I need help with these questions please. Should I send the readings as well or is it fine?

FINDING AN OIL DEPOSIT ACTIVITY You’vejust graduated with your 35. in petroleum geology, and been hired by a prospecting oil company. They have great faith in you as ageologist, so they’ve dropped you off in the field to do a survey of an area. It’s an area of sedimentary rock layers which might contain oildeposits. Your first task is make observations and measurements of the rock outcrops that you can see at the surface, across a transect linethat has been mapped out for you. Your transect line runs east-west across the field area and is 1 km (1000 m) long. Your observation of the geology along this transect line is thatthe area has conglomerate rock at the surface, and that the conglomerate layer is dipping (not horizontal) along the line. From the western endof the transect to about 600 m, the conglomerate layer is dipping down to the west; around 600 m the conglomerate layer is horizontal; andfrom about 600 m to the eastern end of the transect, the conglomerate layer is dipping down to the east. Given these observations, the oil company decides to drill five boreholes along the transect. They give you the well log observations at the fiveboreholes. Use the grid on the last page to make a cross-section of the transect. Draw a very thin rectangle at the locations of the five boreholes, listedbelow, and indicate (make a mark) in the rectangle the depth and orientation of all the rock layers observed in the boreholes. Your marksshould be at the appropriate depth, and should be angled in the direction (west or east) of the dip of the rock layer. You should assume that allof the rock layers follow the conglomerate layer in their dip, i.e. where the conglomerate clips west, the shale under it also dips west. BOREHOLE 1: 100 meters from the western end of the transect From surface to 230 meters deep conglomerate 230 — 275 meters shale275 — 400 meters sandstone
