  • Mechanical coupling of tubulars
    Patent number: 11428054
    Abstract: A tubular for use in the creation or completion of, or production from, an oil and/or gas well. The tubular comprises; an elongate main body; a stab-in connector element located at an end of the main body; and a rotatable connection sleeve disposed coaxially around a first end portion of the main body at or near said end of the main body. The connection sleeve is configured to provide a mechanical coupling between the tubular and another tubular without requiring rotation of the main body, to thereby provide a stab-in connection between the stab-in connector element of the tubular and a complementary stab-in connector element of the other tubular for electrical power and/or data transmission.
    Type: Grant
