Well, I would say a lot of it is, again, you know, we invested in the Tempers technology, as an example which is extended reach technology, and a lot of what you're doing is just incremental step-outs if you will or extension is of existing technology, whether it's extended reach, whether it's our isolation equipment, again, that's geared towards expanded stages, expanded producers, volumes, etcetera; all the things that we have been talking about. I think the other things that we've got to really focus on our equipment and service interfaces given the complexity of what we're doing in multiple customers on an individual rig site, just to ensure that we're all on the same page, we're working towards the same goals and that we have got good communication and efficient interfaces for our customers operations, that every single day it seems like there's incremental demand a lot of it, too, is just making sure you -- people again , we start ramping activity particularly after this extended downturn. Do I have enough people number one, number two, are they the right tenure, the right experience level. So those are all things that we work on for obviously quality, delivery of services to our customers, safety on location is critical. So a lot of this has to be as you ramp backup -- what's the experience electrical of my people, inspection testing, documentation of our equipment. Again, we have got some key, key equipment on locations so we have to really work on our QAQC as we always do just to ensure that we have got a high-quality product and service offering to our customers.
