| One example of a downhole self-isolating wellbore drilling system to pulverize formation cuttings includes a cutting grinder tool and an isolation tool. The cutting grinder tool can be attached to a drill string uphole relative to a drill bit attached to a downhole end of the drill string. The cutting grinder tool can receive and pulverize formation cuttings resulting from drilling a formation using the drill bit. The isolation tool can be attached to the drill string uphole relative to the cutting grinder tool. The isolation tool can control flow of the pulverized formation cuttings mixed with a drilling mud uphole through the drill string. | ||||||

| The lower end assembly of a measurement while drilling tool is secured against shock and vibration while drilling through the use of a locking cuff, an abrasion ring and a locking nut. A mule shoe at a lower end of the assembly has a diameter sized to allow a pulser helix to pass. The locking cuff is installed on one end of the mule shoe. A poppet housing is attached to an end of the pulser helix opposite the mule shoe. An abrasion ring is received about the external diameter of the pulser helix and is received on a shoulder located between the pulser helix and the poppet housing. An externally threaded lower end of the locking nut is received within a mating threaded bore in the extended locking cuff so that a portion of the locking nut is located between the locking cuff and the poppet housing. Tightening the locking nut within the bore of the locking cuff acts to lock the lower end assembly with respect to the mule shoe. | ||||||

| A sealing system can include an annular seal comprising a resilient material, and a spring which applies a compressive force to the seal as a resilience of the material diminishes, the spring being external to the seal. A sealing method can include installing a seal in a well tool, the seal being compressed radially as a result of the installing, and a spring external to the seal exerting a compressive force on the seal. A well tool can include a seal radially compressed between seal surfaces of the well tool, due to the seal having a greater radial dimension as compared to a radial distance between the seal surfaces, and a spring which exerts a compressive force on the seal, the spring being external to the seal. | ||||||
