The invention relates to oil wells and/or gas wells and more particularly a device and a method for acquiring and transmitting data in the wells based on an equipped tubular component (1) which comprises an internal surface (2), an external surface (3) and a main axis (X), an internal antenna (4) which is located on the side of the internal surface (2), an external antenna (5) which is located on the side of the external surface (3), which may comprise an opening (6) which extends from the external surface (3) and opens onto the internal surface (2), an electrical conductor extending in said opening (6).

A method to manipulate a well, comprising running an apparatus (60a) having a container (68a) with a volume of gas at a higher pressure than a surrounding portion of the well. The well is isolated, and a wireless control signal, such as an electromagnetic or acoustic signal, is sent to operate a valve assembly (62a) to selectively allow or resist fluid exit from a portion of the container (68a), via a port (61a). Some of the pressurised gas may itself be expelled in to the surrounding portion of the well, or it may be used to drive a fluid out of the container, such as an acid.

A method of forming a high temperature sensor includes preparing a substrate having a surface from an electrically insulative material having a first coefficient of thermal expansion (CTE), preparing an electrical conductor from a metal material having a second CTE that is different from the first CTE, and creating an interface between the electrical conductor and the substrate with a CTE blending medium that is provided between the substrate and the electrical conductor. The CTE blending medium accommodates differing thermal expansion rates of the substrate and the electrical conductor at temperatures of at least 700° C.

Planning a wellbore includes determining drillability values from surface drilling parameters for an offset wellbore. The drillability values are used to prepare a protein code sequence of protein codes assigned to a range of drillability values. The protein code sequence from the offset wellbore is used to develop a protein code sequence for a planned wellbore. A machine learning model analyzes the offset surface drilling parameters and protein code sequence, and provides target surface drilling parameters for the planned wellbore.
