... was to formulate RDF Breaker. These wellbore productive fluids are designed to attack specific RDF mudcake components; an enzyme and a chelant with the functionality to consume the starch and calcium carbonate components, respectively, minimizing reservoir damage. The results show that the temperature stabilizer...

..., stabilizers are commonly applied along with the foaming agent. This paper describes the comparison testing and several offshore applications of a new liquid foam stabilizer that improves logistics and flexibility on the rig, and prevents excessive viscosity and foaming during mixing. The new liquid foam...

... Abstract Deepwater drilling and cementing have been a challenge due to the low temperature at seabed, low fracture gradients, shallow water flow, gas hydrates, etc . Foamed cementing is one of the best practices that have been used for deep water wells. Dry foam stabilizers have been used...

... of the condensate into the gas pipeline and a full crude stabilizer. It was determined that a hybrid (a Condensate Stabilization System) of the two options was the most economical option due to the ability to recombine the stabilized condensate with the crude oil for sales. This paper addresses the reasons...

... directional casing while drilling (CwD) performance. The combination of rotary steerable systems and CwD is a natural solution to directional wellbore stability problems. It capitalizes on the pinpoint control of RSS s while rotating the casing to heal wellbore wall problems. This paper presents a comparison...

... was required to hit each of these sands within the closure. In addition to difficulties such as target tolerance, torque and drag, hole cleaning, and wellbore stability, normally expected in extended reach wells, this well presented a number of unique problems. Among the unique problems were the relatively...
