.... Evaluation of cement jobs continues to be an important topic, and paper SPE 199578 validates ultrasonic evaluation techniques in simulated downhole well conditions. Extra reading includes lost circulation, expanding cements, and plug and abandonment operations.I am pleased to note that each...

... and response time, total influx volume, and reservoir drawdown. Furthermore, after the SSBOP is closed, the conventional well-control response is subject to significant residual risks in the form of stuck pipe, lost circulation from chokeline friction, and the exceeding of kick tolerance. Finally, closing...

... cement isolation. Estimation of Channel Size Fluid-flow calculations and a hydraulic simulator were used to estimate the size of channels in the cement. The calculations were based on the real data of treated-water circulation. The circulation was established between the production tubing...

The Red region defines the conditions in which it is deemed that some limits of the primary barrier would be exceeded during...

The one-trip OBC ICD completion does not allow an inner-string application. Therefore, circulation while running...

A rheology-control unit uses electric variable-frequency-drive pumps to add FR and other chemicals to the fluid and to provide the ability to change dosage on the fly. These pumps...

...-trip string down, it was decided to pull out with the BHA and cement back the hole and prepare for a sidetrack. A considerable amount of cuttings and 10% mechanical cavings were circulated out during this wiper trip. An 8½-in. sidetrack was performed immediately below the 9?-in.-casing shoe...

..., and they can be added to both oil- and water-based fluids. A density reduction of up to 2.086 lbm/gal is possible when using HGSs. HGS addition helps reduce density and, consequently, the effective circulating density (ECD). Addition of HGSs to a lightweight drilling fluid allows consistent, stable properties...

... Annular-pressure-while-drilling (PWD) data are commonly available through measurement-while-drilling (MWD) services and have the potential for fluid-level detection. But until recently, mud-pulse technology could provide data only during dynamic conditions when the circulation rate exceeded a minimum...

... excessive equivalent circulating densi- ty (ECD) on the wellbore while in mo- tion. It was also decided that the mud cap should be separated from the drilling fluid by a high-viscosity pill of predeter- mined length. The viscous pill was made by adding viscosifier to the mud samples taken from the rig...

In deeper water, pressure on exposed formations created by a tall column of annulus returns in marine risers grossly overbalances many reservoirs, resulting in a higher proportion of undrillable prospects...

These included low rates of penetration and fracture-induced losses because of the equivalent-circulating-density (ECD) effect. Managing the ECD became the main driver...

Another problem discussed in this paper is severe lost circulation while drilling. Uncontrolled losses to the formation...
