Paper Number: SPE-209994-MS
... to accelerate early compressive strength development. This technique is made possible through a novel stabbed-in inner string cementing technology which also reduces operational risk for the cement job and saves rig time by eliminating conventional cement shoe tracks. The pre-project planning included...
