BHF, HDF, TCF, SBS firing systems oil

[Enote]

Уважаемые, пришлось таки переводить скважинное оборудование. В результате намертво застрял на фразе
The SXAR is compatible with the BHF Bar Hydrostatic, HDF Hydraulic Delay, TCF Trigger-Charge and SBS Side-by-Side firing systems.
Как правильно называются эти системы стреляющих головок?
Речь идёт об устойстве сброса перфораторов, весь текст лежит здесь: http://www.slb.com/content/services/perforating/tcp/gunrelease/sxar.asp
Спасибо

Вот здесь уже смотрели?
In a permanent completion, the completion string, including all downhole hardware and guns, is conveyed into the well on the production tubing spaced so that the guns are opposite multiple zones of interest after the packers are set. The underbalance is created by swabbing; then, the guns are fired by pressuring up the string with nitrogen to fire the hydraulic delay firing heads. The other heads may then be fired with the drop bar or the trigger charge head.
