After casing is run, one of the most critical stages of well construction begins: Cementing Operation.
Cement slurry is pumped into the annulus between the casing and the wellbore to provide zonal isolation and long-term well integrity.
Main Objectives:
✅ Secure the casing
✅ Prevent fluid migration
✅ Protect groundwater zones
✅ Create zonal isolation
✅ Improve well integrity
Main Steps:
1️⃣ Spacer Pumping
2️⃣ Cement Slurry Pumping
3️⃣ Top Plug Launch
4️⃣ Displacement
5️⃣ Plug Landing
6️⃣ Waiting on Cement (WOC)
Poor Cementing Can Lead To:
❌ Gas Migration
❌ Channeling
❌ Sustained Casing Pressure
❌ Corrosion Issues
❌ Well Integrity Failure
Industry Quote:
“A Well Is Only As Good As Its Cement.”
