A loose term used to described oil fields that produce at nearly the same rate form day to day.

To place stands of drill pipe and drill collars in a vertical position to one side of the rotary table in the derrick or mast of a drilling or workover rig.

Compare lay down pipe.

See spontaneous potential.

A well drilled or completed for the purpose of supporting production in an existing field.

A fine-grained sedimentary rock composed mostly of consolidated clay or mud.

Shale is the most frequently occurring sedimentary rock.

Abbreviation: static bottomhole temperature

Any one of several methods by which the loose, unconsolidated grains of a producing formation are made to adhere to prevent a well from producing sand but to permit it to produce oil and gas.

1.

The well cuttings obtained at designated footage intervals during drilling.

From an examination of these cuttings, the geologist determines the type of rock and formations being drilled and estimates oil and gas content.

2.

Small quantities of well fluids obtained for analysis.

Sandstone, shale, and limestone are sedimentary rocks.
