The drilling system withstands downhole conditions at the bottom of the borehole and drilling conditions due to the constant movement and vibration. The drilling system includes a drill bit and a sensor system with a system housing, a primary power supply and interior sensor. The primary power supply includes piezoelectric panels for converting radial vibration into energy. The interior sensor is locally powered by the primary power supply at the remote downhole location at the bottom of the borehole. The interior sensor collects data related to a downhole condition and is in communication with the primary power supply to generate confirmed data based on the amount of energy generated by the primary power supply. The confirmed data is more accurate and reliable than the data collected by the interior sensor and can be used to guide the path of the drill bit through the rock formation in drilling operations.

A packer module with selective control and fluid bypass can be interactive with other packer modules in a system for isolating and evaluating. The packer module includes a motor section, a conversion section, a control section, a sealing member, and an isolated flow path section. The control section includes a ramp sleeve cooperative with the sealing member to set a retracted configuration, an initial sealed configuration, and an isolated sealed configuration of the sealing member. The isolated flow path section includes an isolated flow path channel. The isolated flow path channel can only be opened with the sealing member in the isolated sealed configuration so that a zone formed by the packer module can be isolated and evaluated. Measuring and detecting instruments along the different flow paths through packer module evaluate the fluid properties of the bypass fluids and isolated fluids through the different flow paths.

The invention relates to a connecting assembly to be plugged into a mating receptacle in a wellbore, comprising a first sleeve including a second sleeve and having a top connecting end and a bottom connecting end, characterized in that: &#x2014;the first sleeve comprises the bottom end and has a top end opposite to said bottom connecting end, said bottom connecting end being provided with an end cap for preventing entrance of materials and capable of being opened; &#x2014;said second sleeve comprises said top connecting end located outside of the first sleeve and has a bottom end opposed to said top connecting end; &#x2014;said connecting assembly comprises a locking mechanism adapted to lock said second sleeve in a position relative to said first sleeve such that the bottom end of the second sleeve is inside said first sleeve, and &#x2014;the dimensions of the first sleeve and second sleeve are adapted such that when said locking mechanism is unlocked, said second sleeve is allowed to move relative to said first sleeve to impinge and open said end cap.

A steering assembly includes a housing having a longitudinal axis, a mandrel having a front connecting extremity and a rear connecting extremity, the mandrel passing through the housing and arranged in a first position coaxially to the longitudinal axis of the housing, a deflector device configured to exert a side force on the mandrel to offset the front connecting extremity of the mandrel from the longitudinal axis, and a tool face assembly configured to rotate the front connecting extremity of the mandrel in a desired direction.
