A brief description of how MACS and Unlimited-Circulation Bypass Valve (UCBV) operate The operation of the two tools is basically the same, the tool enters the well with the drill string, and is closed at the beginning, when the well produces a leakage ...

Perforation density refers to the number of perforated holes per meter of length. In general, a high perforation density is required to obtain maximum capacity, but when selecting the perforation density, the density cannot be increased indefinitely, and t...

As oil and gas extraction activities move deeper into complex and challenging geological conditions, accurate downhole positioning and navigation are becoming an increasingly important part of the oil drilling industry. Gyro inclinometers can help dri...

The MMRO gyro inclinometer is a single multi-point inclinometer with self-seeking north function. The MMRO gyro inclinometer has the advantages of small size, impact resistance, high temperature resistance and high measurement accuracy. The MMRO gyro i...

Common perforating gun operations can be divided into three ways: Wireline Conveyed Perforating (WCP), Through Tubing Perforation (TTP), Tubing Conveyed Perforating (TCP).

The unlimited-cycle bypass valve is a set of short sections that can be opened and closed multiple times, generally installed in special drilling tool combinations such as orientation, acceleration, and logging while drilling, which can open and close bypass holes in time according to downhole conditions for special operations, enhance the applicability of special drilling tool combinations, help improve production efficiency, and reduce well control risks.
