The vapour cone effect is caused by pressure differences around the aircraft. A sudden drop in pressure associated with high speed allows water vapour, which is normally invisible, to condense as fog.

IV fluids are routinely administered before and during the placement of an epidural to reduce the chance of a drop in blood pressure, a common side effect of this pain relief route.

To make the development effect better, we reduce well spacing to develop the precursor experiment, infill well network appropriately, build effective producing pressure drop.
