Application of RF ‐ Safe Technology in Marcellus Shale ll h l • How to How to implement RP 67, and RP ‐ 67 and more specifically specifically Radio Silence on Silence on location? The answer was to show the cost benefits to the client

Rf ‐ Safe Unintended Consequences Rf Safe Unintended Consequences A little bit of a wiring issue – not hard, just not that easy Components like PX ‐ 1 and RED introduce one more point for failure Thus, even though there was a safety and economic gain, some (or all at times) of the gain (or all at times) of the gain could be absorbed by the dreaded misrun Plugs not RF ‐ Safe l f
What about RF ‐ Safe Addressables What about RF Safe Addressables • Wire complexity • RF Safe guns and plug • RF ‐ Safe guns and plug, yes • System can be checked y on surface with test box • Case study data shows • Case study data shows far lower failure rates than other RF ‐ Safe systems • SQ improved along with Safety with Safety

RF ‐ Safe Addressables cost $ How can we pass that $ in a downturn h $ d • It is easy if – operating company understands the total cost of operations including impacts for SQ and HSE • Client quote from last month “ …with the last project (34 stages)…calculated a savings with the last project (34 stages) calculated a savings of 59.5 hours” $25,000 per day spread ($61,975 – savings) $34,000 additional cost (Net savings $27,975) Safer Operations / Better SQ (less misruns, less fishing, etc) What is the real cost then? etc). What is the real cost then? The Results: Those companies that are running “Addressables” in the Marcellus are still growing despite the market despite the market.
