Accelerators - Halliburton
Accelerators speed up the time required for a cement slurry to become hardened in a reaction process that shortens WOC (Wait On Cement) time and provides faster drill out, thus saving rig time. This reaction process is known as cement hydration whereby water induces chemical reactions that ultimately lead to bonding.

Chapter 6: Well Cementing Flashcards Quizlet
1. Drilling engineer is concerned with the selection of the best cement composition and placement technique for each required application. 2. The cement composition and placement technique for each job must be chosen so that the cement will achieve adequate strength and sealing property soon after being placed in the desired location.
The early strength of the concrete can be increased if it is kept damp during the curing process. Minimizing stress prior to curing minimizes cracking. High-early-strength concrete is designed to hydrate faster, often by increased use of cement that increases shrinkage and cracking. The strength of concrete changes (increases) for up to three
