Lex – Solution to efficiently produce oil in wells having fluid temperatures up to 392 °F (200 °C)

Solution to efficiently produce oil in wells having fluid temperatures up to 392 °F (200 °C)

We have developed the improved pumping equipment adapted to high temperatures, which ensures steady operation in the harsh conditions of geothermal wells with temperatures up to 392 °F (200 °С).

Solution to efficiently produce oil in wells having fluid temperatures up to 392 °F (200 °C)

The operation of wells with fluid temperatures exceeding 302-392 °F (150-200 °С) using standard pumping equipment not adapted to high temperatures is impossible: each unit is incredibly overheated, which leads to the destruction of pump components and melting of motor and seal components.

In our solution, we use high-temperature elastomers and mechanical seals in the hydraulic protection unit. Lex high-efficiency PM motors have no electrical or magnetic losses and are less heated. In addition, they use a high-temperature-resistant synthetic oil and a special wire compound. 

All these improvements have provided reliable, stable operation of submersible equipment with a comprehensive delivery range, with internal engine temperatures reaching 482 °F (250 °С) in wells with extreme fluid temperatures up to 392 °F (200 °С).
