Abstract |
|
Acid |
A material with a pH less than 7. Used in either an acidizing job or an acid frac job. Usually either HCl (hydrochloric acid) or HF (hydrofluoric acid). |
X |
|
|
Acidizing_Additive |
An additive used in the formulation of an acidizing fluid to be used in an acidizing job. |
X |
|
|
Gravel |
A uniform graded commercial silica sand that is placed in the wellbore and perforation tunnels for the purpose of mechanically retaining formation sands. (SPE Petroleum Eng Handbook). |
X |
|
|
Gravel_Pack_Fluid |
Fluids used for a gravel pack job. |
X |
|
|
Gravel_Pack_Fluid_Pty |
Properties of gravel pack fluid. |

|
|
Gravel_Pack_Screen |
A screen placed opposite perforations in sand control. A metal filter assembly used to support and retain the sand placed during gravel pack operations. A range of sizes and screen configurations is available to suit the characteristics of the well bore, production fluid and the formation sand. |
X |
|
|
Gravel_Packing |
A sand-control method used to prevent production of formation sand. In gravel pack operations, a steel screen is placed in the well bore and the surrounding annulus packed with prepared gravel of a specific size designed to prevent the passage of formation sand. The primary objective is to stabilize the formation while causing minimal impairment to well productivity. |

Gravel_Packing_Stage |
A section or portion of the gravel packing activity. For example lower circulation, squeeze stage, upper circulation stage, etc. |
X |
|
|
Proppant |
A granular substance (sand grains, aluminum pellets, or other material) that is carried in suspension by the fracturing fluid and that serves to keep the cracks open when fracturing fluid is withdrawn after a fracture treatment. (MMS). |

|
|
R_Diversion_Method |
The diversion method used to ensure placement of the stimulation fluid. For example Ball Sealers, Bridge Plug and Packer, Chemical Particulate, etc. |
X |
|
|
R_Gravel |
The type of gravel used in the fluid formulation. |

R_Stimulation |
A classification of Stimulation activities like Acidizing, Acid Fracturing, Hydraulic Fracturing etc. |
X |
|
|
R_Stimulation_Stage |
A classification of Stimulation Stage activities like Clean, Flush, Circulate, etc. |
X |
|
|
Stimulation |
Any process undertaken to enlarge old channels or to create new ones in the producing formation of a well (e.g., acidizing or formation fracturing). |
X |
|
|
Stimulation_Evaluation |
The results of tests performed after the stimulation or stimulation stage activity is completed. |
X |
|
|
Stimulation_Fluid |
The fluid used in the stimulation of production from a borehole. Ex gravel pack fluid, acidizing fluid, frac fluid, etc. |
X |
|
|
Stimulation_Stage |
A section or portion of the stimulation activity. |
X |
|
|
Wash_Pipe |
In the context of gravel packing, it is a tubular that extends from the crossover tool, inside the blank pipe and screen, to the bottom of the screen. (SPE). |
