Tuha Oilfield

Wenxi3-4*, Water lnjection Well

This is a water injection well in Tuha oilfield. It is a low porosity and extremely low permeability well. After three times of acidizing, the cumulative water injection was 15,000 cubic meters, injection pressure is 23MPa(mega pa), daily injection is 13 cubic meters. After U-TEM operation, at the same injection pressure, the daily injection volume reaches 42 cubic meters, and the daily injection increased 29 cubic meters, which far exceeded the expectation of the client.

Before

U-TEM operation: The oil laver of the well is poorly developed and generally connected with the surrounding water injection. After three times of acidizing, the cumulative water injection was 15000m3.Waterinjection pressure is 23MPadailyinjection is 13m³.

After

U-TEM operation: The injection pressure is 23Mpa the daily injection volume is 42m³, and the daily injection increased 29m³.
