Our plug systems are industry standards for separating displacement fluid from cement, effectively wiping tubulars, and reducing cement contamination when doing a cement job. We offer the widest choice of proven plug systems for every application.
The LFC™ four-plug system consists of two unique liner wiper plugs and two pump-down plugs that isolate cement from wellbore fluids and minimize contamination for improved cement quality. It can be used in conjunction with an external casing packer and pressure-actuated cementing (PAC) valve for two-stage liner cementing.
Our pump down plug or (drillpipe dart) is used to wipe the running string behind (and sometimes in front of) the cement. The plug can be used to latch into a liner wiper plug or can be used to wipe both the running string and the liner casing in small-diameter liner applications. Multiple darts may be used to more effectively wipe tubulars and reduce cement contamination. Various wiper fin, nose and latch configurations are available to fit a wide range of applications.
The Solo Plug™ liner wiper plug system separates displacement fluid from pumped cement. Its multiple-fin arrangement wipes a wide range of casing weights. The Solo Plug is designed to be compatible with standard Type I and Type II landing collars, and will withstand high differential pressures in both directions when the plug is latched. With the nose seals landed, the plug's fins are not required to hold pressure and—most important—the cement stays where you want it. Nose seal and positive latching results in increased differential rating of 5,000 psi (345 bar) from above and below in most sizes. A ceramic pump down plug seat within the body of the Solo Plug eliminates potential erosion at high circulation rates.
The composite Solo Plug and composite landing collar increase the reliability and performance of current industry standard plugs while easing the drillability of the shoe track. The body of the new Solo Plug is molded with a high-strength composite material that can be drilled out easily, without compromising performance. Multiple wiper fins increase displacement efficiency. The composite pump down plug seats and latches inside the composite Solo Plug. A nose seal allows the plug to withstand 5,000 psi pressure differentials from above. The running tool incorporates a safety device to ensure that the cement job is displaced from the liner.
Our Type I landing collar is typically run in the liner one or two joints above a float collar or shoe. The Type I landing collar provides the seat and latch profile to catch the liner wiper plug at the completion of cement displacement. Landing collars and plugs are designed to ensure rapid and complete drill-out. Landing collar bodies are available in virtually all weight, material, and thread combinations.
Our Type II landing collar is usually run in the liner one or two joints above a float collar or shoe. Landing collars provide the seat and latch profile to catch the liner wiper plug at the completion of cement displacement and to ensure rapid and complete drill-out. The Type II Landing Collar has all of the features of the Type I Landing Collar plus an integral ball seat below the liner wiper plug seat. When a setting ball is dropped and seated, pressure may be applied to activate hydraulic devices in the liner string such as hydraulic-set liner hangers and external casing packers. A further increase in pressure shears out the ball and seat, restoring full circulation through the shoe for cementing operations. Landing collar bodies are available in virtually all weight, material, and thread combinations.
