1.Balanced drilling allows for discovering more oil and gas formations.

2.Timely detection of overflow and prevention of blowouts, ensuring intrinsic well control safety

3.Prompt recognition of incidents such as gas contamination, well leakage, and borehole collapse enables the taking of technical measures in advance, thereby saving time for addressing complexities and providing a basis for determining an optimal mud density, which in turn reduces costs and enhances the Rate of Penetration (ROP).

4.Protect the hydrocarbon reservoir, which enables the extension of horizontal intervals, thereby increasing the production of a single well.

5.Reduces well control risks by making bottomhole equivalent mud density (ECD) easy to control while calibrating the designed three-pressure profile.

6.Provides a basis for later optimizing the wellbore structure of appraisal well and development well, and simplifies well structure and reduces technical casing in complex formation pressure zones.

7.When drilling in formations prone to blowouts and leaks, a safety measure is added, so drilling can continue. Reduces non-productive time.

8.Can be extended to professional field such as managed pressure cementing, managed pressure completion and managed pressure logging, which helps lower completion fluid costs and improve cementing quality.

Suitable for both offshore and onshore. Suitable for development of oil formations in pressure decay areas. Suitable for drilling of exploratory wells (drilling in unusually high and low pressure formations) .

Achievements:

Between 2019 and 2024, we successfully completed over 30 well services involving various types of fine pressure control operations, with a maximum well depth of 8,200 meters, including in hydrogen sulfide work environments; and we have received commendations from our clients.
