Schlumberger was recognized for two new technologies this year. One award was for the company's FUTUR active-set cement technology, which has the unique ability to automatically self-heal in the presence of hydrocarbon leaks through cracks or microannuli created by post-completion changes in the regional stress field. Cyclical pressure or temperature regimes can cause changes in casing stress that damage the hydraulic integrity of well cement, often years into production or even after abandonment. But if the well has been treated with the active-set cement, any resulting leaks will be repaired automatically, without any need for intervention from surface.
