Workover and completion operations use fluids that must control the well without damaging the reservoir. Gilsonite can play…
Kontrola filtrata HPHT i stabilizator šejlova za isplake na bazi ulja i vode.
Ključne prednosti
- Smanjuje filtrat HPHT
- Stabilizira šejlove i mikropukotine
- Smanjuje zakretni moment, trenje i prihvat
- Stabilan iznad 150 °C
Opis proizvoda
Gilsonit za bušenje melje se na oko 200 mesha i nudi u nekoliko raspona točke razmekšanja. Na temperaturi dna bušotine čestice omekšaju i začepe pore i mikropukotine, smanjujući filtrat HPHT, stabilizirajući šejlove i poboljšavajući podmazivanje.
Primjena
- Isplake na bazi ulja i sintetike
- Isplake na bazi vode (s disperzantom)
- Čepovi protiv gubitaka
- Horizontalne i HPHT bušotine
