Specialty Foam Wiper Ball For Drilling & Tubing String

Specialty Foam Wiper Ball of Merit

Specialty foam wiper ball of Merit is developed to wipe drill pipe or tubing string wiping of cement, fluids, or debris, and can be used to separate fluids. Over 18,000 Merit’s foam wiper balls have been used successfully in the past two years. Their ability to effectively wipe tubular drill pipe has been documented in the following case histories.

We are only and unique genuine and original procurer of certified 11 ” specialty foam wiper ball to wipe 8 5/8″ casing in Canada, Thailand, China and other offshore oilfields.

Specialty Foam Wiper Ball of Merit

The MERITs brand new specialty foam wiper ball (FWB) is made of natural rubber and can be used in a temperature range of -40°F (-40°C) to 302°F (150°C).

The foam ball has a parting stretch of 380 to 440%, which means it can pass through small restrictions without being damaged.

Thousands of FWB have been utilised to wiper tubulars and drill tubing, as well as isolate fluids during cementing operations, with great success.

The wiper balls can be loaded into drill pipe or tubing connections. It easily passes through internal upset restrictions such as mechanical setting tools, diverters, and liner running tools and multiple balls can be pumped if necessary.

MERIT’s wiper foam ball has been used with all types of drilling and displacement fluids.

By the way our wiper foam balls the best match one and only output with oil & gas industry specific cementing wiper foam balls launcher. There is no an other profitable alternative to our products offshore and onshore.

Multiple sizes of drill-pipe needed to be wiped while spotting the cement plug. This would eliminate the need to send the pipe onshore for cleaning and the risk of the cement sheath falling on top of MWD tools and plugging them. On a previous well, 37 joints of drill pipe were sent for cleaning due to concerns of cement scale buildup on the inside of the drill pipe. We provided a wiper ball that was pumped after each plug, and it successfully wiped clean 6-5/8-in., 5-in. and 3-1/2-in. drill pipe that was in the hole while setting each of these plugs.

On a North Sea well, a wiper ball was pumped through 3051 meters of 5-in. drill pipe and 258 meters of 3-1/2-in. drill pipe. The foam ball removed cement scale from the drill pipe ID after a cement plug was set. The customer was pleased with the results and no leftover cement was reported in the drill pipe.

Casing, tubing, and drill pipe IDs are wiped with open cell foam balls for 2 7/8 inch tubing drill pipe. Wiping balls made of foam can separate fluids, chase a wiper dart to increase wiping efficiency, or wipe drill pipe during a bit trip. The working temperatures are 40°F to 4°C to 300°F (150°C) and are made of natural foam rubber.

Wiper ball, WP10007 (7″, actual size 6.89″, typical wiping range 5.50″ to 2.38″, minimal restriction 1.00″, temperature range 40℉ (4℃) to 302℉ (150℃), parting stretch of 380 to 440%).
