Gushers like Spindletop and BP/Transocean Macondo disaster are because the reservoir is under pressure. Many fields have gas in them as well as liquids. Some of the liquids are in liquid form in the reservoirs but when the pressure is off, they turn to gas [such as propane and butane are liquids in a tank but turn to gas when released to the atmosphere]. Those volatile liquids act as excellent propellants to force liquids to the surface and into the sky. The compressed methane also acts as a propellant as the energy of compression is released.

Oil reservoirs are by definition porous so the liquid can flow, often very quickly, to any low pressure area such as the well hole. Fracking is needed when the reservoir material is not impermeable, so that the liquids can flow along the cracks that are made.

Glaciers in NZ were down at sea level a couple of centuries ago during the Little Ice Age. The subsequent warming has seen them retreat for several kilometres all through the 19th century and 20th century, starting from before any significant CO2 production by people.
