Cement composition comprising mixture of organic and inorganic fibres for curing severe losses especially in the reservoir section |
| abstract |
Disclosed is a method for controlling loss circulation and simultaneously strengthening a weakened formation when drilling for oil. This invention relates to the permeable subterranean formation and natural and induced fractured formations that encounter severe losses and their treatment with a composition composed of long rigid organic fibre with different type of fibres selected from a category of organic or inorganic fibres along with different particle sizes that orientation of fibres and packing of the solids shows a good blockage effect to resist the loss and later the final set material develop required compressive strength to cure those losses and strengthening the structure. |
