B & T Accelerator Assembly Sheets
The B & T Accelerator is used to provide spring-loaded jarring action, usually at a surface level. It stores its energy for when an overpull occurs. This will make the assembly accelerate upward to where the point of impact was, thus increasing the amount of force being generated. It may also act as a shock absorber for when assemblies are being used at shallow depths.

B & T Anti-Blow Up Tool Assembly Sheets
The B & T Anti-Blow Up Tool is installed in the tool string above the B.H.P. equipment. The weight of the B.H.P. equipment will keep the dogs retracted.
If a sudden surge of pressure were to occur below the tool string, the memory pressure gauges and other equipment would move upward, releasing the dogs outward. The dogs would then engage the inner tubing wall, thereby preventing the tool string from being blown up the tubing.

B & T Rope Socket (Multi-Strand) Specifications Sheets
The B & T Multi-Strand Rope Socket is used to attach multi-strand lines with the wireline tool string. This slip-type rope socket is used with small lines up to 7/32”. Each rope socket is able to maintain a specific weight, proportional to the nominal size. In the event that the tool string becomes stuck, the slips will break the wireline, allowing it to then be pulled up.

B & T Stem Specifications Sheets
The B & T Stem is used to add weight to the tool string to counteract upward well bore pressure. This allows easy descent of the tool string. It is also used to increase the jarring effect of Link Jars and Tubular Jars. Tungsten Stem is available upon customer request, and will add significantly more weight per square inch.
The most common lengths of Stem are 2', 3', and 5' but B & T is also able to produce any length Stem as to meet customer requirements.

B & T Tubular Jar Specifications Sheets
The B & T Tubular Jar performs the same function as the B & T Link Jar, but the holes in the body of the Tubular Jar allow fluid bypass. This gives Tubular Jars an advantage compared to Link Jars, because where a Link Jar might lock up or buckle at full stroke in a tubing with debris, a Tubular Jar could allow the debris to pass through it and still manage to jar the tool string.
By allowing fluids to flow through the holes in the body of the Tubular Jar, the harmful effects of the debris in the well fluid and even faults in the wire on jarring impact is significantly reduced.
