If you mean drill horizontally through the dirt,, I'm no engineer but fitting a length of pipe with a water tap then extend the pipe as the water washes away the dirt from the working end under the slab and flushes out the sediment seems like it would work.
The drilling pipe comes in sections and they periodically stop drilling to add another section. This way they can drill to almost any depth desired. The physical drilling head on the tip of this pipe is rarely more than a couple of feet long.

No...what in the world would possess a man to think that explosives would be safe to use on an oil well. The proper way to drill an oil well would be to use a "Drill Bit" followed by a series of tools and special pipe to make up the "Bottom hole assembly" or the BHA. As the bit drills deeper a series of pipe are added to the top of the drilling pipe, these are call "Drill Pipe"
basically you need a pipe and a 1mm drill and you drill holes half an inch apart and place and plug up the end with something. make a hole on the end of your rubber cork and attach a gas pipe and fill it with the gas of your choice i suggest propane and light it
