World record RLWI operations to retrieve asphaltenes in deepwater
Max. depth5,731 ft
Max. temperature100°F (38°C)
The toolstring was worked free and recovered to surface. There the bit was found packed with solid debris while the bailer sections were filled with dense, hard packed asphaltenes, which had not been expected. The operator concluded that these deposits would likely be present throughout the well. Therefore they decided that it would be best to analyze the samples recovered by the RCB and prepare a plan before attempting to mill out potentially tens of thousands of feet of deposits.
This operation was the first time asphaltenes had been recovered using e-line cleaning tools. It was also the world record for water depth, but since then we have beaten that record considerably by performing an operation at 8,087 ft water depth in the Gulf of Mexico.
The Well Tractor was regarded as a revolution in the industry when it was introduced in the 1990’s. It enables operators to extend the reach of traditional e-line deployment into highly deviated and horizontal wells.
The Well Cleaner Reverse Circulating Bit (RCB) integrates a rotary bit with a suction system to provide the combined benefits of both in one tool. This design breaks through hard packed debris and recovers the cuttings into the integrated bailers.
