Across
  1. 5. The working platform approximately halfway up the derrick or mast in which the derrickman stores drillpipe and drill collars in an orderly fashion during trips out of the hole.
  2. 6. The inventor of the earliest form of the ESP was Armais ...
  3. 10. The stratigraphic principle that, in the case of undeformed, flat-lying strata, younger layers are deposited atop older ones, such that the top layer is youngest and underlying layers increase in age with depth
  4. 12. A descriptive term for a fluid with shear-thinning characteristics that does not exhibit thixotropy
  5. 13. A measure of deviation from a straight line.
  6. 14. The permanently frozen subsoil that lies below the upper layer (the upper several inches to feet) of soil in arctic regions
  7. 15. A series of alcohols with general formula C2nH4n+2On+1, widely used as antifreeze. It may be used in drilling fluids as gas hydrate inhibitors.
Down
  1. 1. An injection pattern in which four input or injection wells are located at the corners of a square and the production well sits in the center.
  2. 2. A crystalline solid consisting of water with gas molecules in an ice-like cage structure. The general term for this type of solid is
  3. 3. The top part of a valve, attached to the body that guides the stem and adapts to extensions or operators.
  4. 4. A compound, typically a metallic salt, mixed with a base-gel fluid, such as a guar-gel system, to create a viscous gel used in some stimulation or pipeline cleaning treatments.
  5. 7. A percentage share of production, or the value derived from production, paid from a producing well
  6. 8. In sucker-rod pumping, a situation that occurs when the stroke length at the downhole pump is shorter than the surface stroke length.
  7. 9. The loss of energy or amplitude of waves as they pass through media. Seismic waves lose energy through absorption, reflection and refraction at interfaces, mode conversion and spherical divergence, or spreading of the wave.
  8. 11. A type of geochemical analysis in which a rock sample is subject to controlled heating in an inert gas to or past the point of generating hydrocarbons in order to assess its quality as a source rock, the abundance of organic material in it, its thermal maturity, and the quality of hydrocarbons it might generate or have generated.
