Abstract:A major challenge that is faced during the well construction phase is to cement the formations holding narrow pressure margins between the pore and fracture gradients without inducing losses that could compromise the integrity of the cement barrier. The paper will review two case studies for deploying an engineered loss circulation (LC) spacer system as an important solution for primary cementing operations in the case study wells with such narrow pressure margins.
One of the case studies well i… Show more
