Agenda Horizontal Completion Methods – Plug and Perf Completion – RapidSuite™ Technologies • Ball Dropper • RapidStage™ System • RapidFrac™ System • Isolation Methods2
Plug and Perf Completion Production string is run and cemented in place Flow path is established at the toe – RapidStart™ Initiator sleeve – TCP – Wireline tractor Toe is stimulated Frac plug and guns run to depth on wireline Multiple points perforated within the stage All entry points stimulated simultaneously Repeat
Plug and Perf Completion Multiple controlled entry points Maximized reservoir coverage Customizable (# of cluster, interval size, perforations) No rate limit Specific wellbore sections can be targeted Composite frac plugs are milled for full open ID
RapidStart™ Initiator Sleeve Interventionless opening of completion string toe Eliminates perforating gun run for initial treatment in plug & perf applications Provides flow path to pump first Plug and Perf assemblyApplication: Interventionless stimulation treatment and toe opening sleeve in a RapidSuite completion.Current Capability: Shear Pinned Single Pressure ActivatedRun History: > 500 Through December 2011Future Capability: Multi Pressure Cycle RS Initiator for Cemented Application
RapidSuite Technology Efficiencies Reduces stimulation time as much as 50% Reduces water usage and over- displacement Reduces disturbance of proppant pack Multiple or single entry points available7

RapidStage System Completion Single entry points Requires no intervention Specific wellbore sections can be targeted Stimulation cycle time is reduced up to 50% Little or no over displacement of the frac Frac balls and baffle can be milled for full open ID DTS can be included
RapidFrac System Completion Alternative to “plug and perf” process Enables continuous pumping of multi-zone treatments Allows for multiple entry points in a single stage Eliminates wireline intervention and associated risks Reduces water usage and over displacement RapidFrac Sleeves RapidStage Sleeve
The Pros and Cons of Different Fracturing TechniquesPerf and Plug Sliding Sleeve Systems Proven technique preferred by Time between stages is reduced many operators helping improve efficiency Time required between frac Screen outs will result in stages to set the bridge plug significant delays to clean out and perforate is significant wellbore. Screen outs result in significant Limited number of stages due to delays to clean out the wellbore ball sizes. (being addressed by (Frac designs become over opening multiple valves per ball) conservative) Over displacement is reduced to Over displacement is required to place balls or plugs and activate get guns and plugs placed. valves.
Identifying the best completion method A keen understanding of the reservoir, geology, tectonics, etc. is required The well must be placed to take advantage of the most productive reservoir characteristics Well must be drilled & constructed to accommodate the most rigorous anticipated treating conditions and maximize designed treatment placement success Preplanning, interdisciplinary teamwork & close, open collaboration with contractor(s) is essential Expectations need to be realistic & managed Gather as much data early on as possible, and use it! A well established baseline is priceless Technical Advisory Team Presentation 23
