Abstract
A downhole oilfield completion method is provided. The method comprises determining a surge profile for a wellbore and assembling a downhole completion tool having an interior surge volume and comprising a surge attenuation system operable to reduce a surge of the downhole completion tool based at least in part on the surge profile. The method also comprises running the downhole completion tool into the wellbore and surging the wellbore by admitting wellbore fluid into the interior surge volume, the surge reduced at least in part by the surge attenuation system.
Claims20
A downhole oilfield completion method, comprising:
- determining a surge profile for a wellbore;
- assembling a downhole completion tool having an interior surge volume and comprising a surge attenuation system operable to reduce a surge of the downhole completion tool based at least in part on the surge profile;
- running the downhole completion tool into the wellbore;
- and
- surging the wellbore by admitting wellbore fluid into the interior surge volume, the surge reduced at least in part by the surge attenuation system.
An oilfield downhole completion tool, comprising:
- a surge chamber sub-assembly containing at least one constrictor plate to reduce the in-flow of wellbore fluid within the surge chamber when a well is surged.
A downhole oilfield tool, comprising:
- a first perforation gun;
- a surge chamber sub-assembly comprising a pre-determined volume of filler material and a surge volume at approximately atmospheric pressure;
- and
- a surge vent sub-assembly coupled to the first perforation gun and coupled to the surge chamber sub-assembly, wherein the surge vent sub-assembly is operable to open a surge vent in association with detonating the first perforation gun, thereby admitting a surge of a fluid in the wellbore into the surge chamber sub-assembly.
