... environments include low bottomhole circulating temperatures (BHCTs), temperature variance, narrow pressure margins, annular pressure buildup (APB), etc. Cementing operations in these conditions should be engineered such that the equivalent circulating density (ECD) does not exceed the fracture gradient during...

... Abstract The problem of lost circulation occurs almost permanently during drilling operations. When drilling highly permeable, highly fractured, and depleted zones, large drilling fluid losses lead to increased operational expenses. Lost circulation may have several consequences, including...

... circulation event occurs, it is recommended to apply the appropriate fluid solution as quickly as possible to help minimize NPT and maximize wellbore value. Using an engineering model to estimate large fracture widths, a major drilling fluids company has designed new equipment to simulate sizeable fractures...
