Site Preparation
To stake a well, a surveyor accurately determines the well location and elevation. A plat
(map) of the site is prepared and registered with the appropriate government agency. A bulldozer
can be used to grade an access road to the site and make a turnaround. The bulldozer then clears

and levels the site (drilling pad). A drilling pad is commonly 0.016 to 0.024 km in area and is
often covered with gravel. Boards might be laid if the ground is wet. A matting can be spread on
the surface to support the rig and improve drainage. A large pit, the reserve pit, is dug and lined
with plastic next to the drilling rig. It will hold unneeded drilling mud, cuttings, and other
materials from the well. Provisions are made for a water supply at the drilling site by drilling a
water well or laying a water pipeline.
The deeper the well, the larger and stronger the rig has to be to support the drillpipe on
the drill floor as the pipe is being pulled out of the well. Each drilling rig is rated for maximum
depth.
The rig is assembled during rig up and disassembled during rig down. The start of
drilling a well is called spudding in. Spudding in a medium or deep well usually begins with a
small truck-mounted rig that drills a large diameter but shallow hole (7 to 30 m) called the
conductor hole. Large-diameter pipe (50 cm), called conductor casing or pipe, is then run and
cemented into the conductor hole. In soft ground, the conductor casing can be pile-driven
without drilling. The conductor casing stabilizes the top of the well and provides an attachment
for the blowout preventers in areas where shallow gas could be encountered.

Types of Wells
A well drilled to discover a new oil or gas reservoir is called a wildcat or exploratory
well. It can be drilled in an area that has no production (new-field exploratory well) or to test a
new reservoir rock that has no current production in a producing area (new-pool exploratory
well) that is either shallower (shallower pool test) or deeper (deeper pool test) than current
production. An exploratory well can also be drilled to significantly extend the limits of a
discovered field or to significantly extend the limits of a discovered reservoir (outpost or step-out
well). A rank wildcat is drilled at least 3 km away from any known production. If the well does
discover a new field, it is called the discovery well for that field. As soon as possible after a
discovery, the size of the field must be determined.
Field size is determined by stepout or appraisal wells that are drilled to the sides of the
discovery well. If the oil-water or gas-water contact can be located on all four sides of the
