| Résumé: | Cementing of oil and gas wells can be a very delicate operation. Among the
concerns of service companies, during this operation are the nature and conditions of the
formations in well. This is the case of cementing operations in southern Algeria, specifically
on the fields of In-Amen, where the formations in lost zones are naturally weak and highly
permeable. In these areas, drilling fluids (muds and cements) pumped will be, completely or
partially lost, what we call" lost circulation". Thixotropic cements are useful to overcome lost
circulation problems. They are characterized by a special rheological behavior, allowing it to
plug lost zones when they are pumped |
