Evolution of H&P’s Global Rig Fleet * Estimates include existing rigs and announced new build commitments.

U.S. Land Market Trends Today Stronger than expected oil and gas prices for 2014 Increasing proportion of horizontal wells with longer laterals and pad drilling requirements Increasing market demand for AC drive rigs Slightly improving spot market pricing Continued customer focus on drilling efficiency, technology and safety Conversations with customers for additional new build orders continue

H&P’s U.S. Land Fleet Activity (1) (1) Includes completed new builds pending delivery and not generating revenue days.

Delivering Safety – H&P vs. Industry (IADC) U.S. Land Safety Performance (2005 – 2013) OSHA Recordable Injury Incidence Rates H&P = 0.84 IADC w/o H&P = 1.81 Injuries per 200,000 Man Hours

Unconventional Plays Shaping Landscape Well Complexity is increasing: Horizontal and directional wells make up over 75% of wells drilled in the U.S. Extended reach laterals progressively longer Multi-well pad drilling gaining acceptance in more areas This all creates an expanding level of demand for FlexRigs

Increasing International FlexRig Presence Deploying ten existing FlexRig3s from the U.S. to Argentina Five-year term contracts with YPF to work in the Vaca Muerta play in the Neuquén Province All ten rigs expected to be operating by the second quarter of fiscal 2015 Expecting a total of 19 H&P land rigs in Argentina by this time next year, including 15 FlexRigs

As of May 2014 (~1,780 Active Rigs in U.S. Land By Power Type) The Replacement Cycle Continues As of October 2008 (Peak) (~1,900 Active Rigs in U.S. Land By Power Type) Note: The above estimates corresponding to rig activity are derived from multiple sources including Rig Data, Smith Bits, and corporate filings. Additionally, the drawworks capacity of each land rig included in the above analysis was greater than 600 horsepower. Certain assumptions were made on approximately 5% of the active rigs that were not readily identified.

AC Rigs Continue to Gain Market Share Note: The above estimates corresponding to rig activity are derived from multiple sources including Rig Data, Smith Bits, and corporate filings. Additionally, the drawworks capacity of each land rig included in the above analysis was greater than 600 horsepower. Certain assumptions were made on approximately 5% of the active rigs that were not readily identified.

H&P’s Lead in U.S. Land AC Drive Rigs * The above estimates corresponding to U.S. lower 48 AC Drive fleets are derived from Rig Data and corporate filings. **Estimated number of all other available AC Drive rigs not including those owned by HP, NBR, PTEN and PDS.

H&P’s Pad Capable Fleet Roughly half of H&P’s U.S. Land active rigs are equipped with hydraulic skid systems. Our pad capable fleet is fully utilized. Customers continue to contract/add skid systems to existing FlexRigs.

H&P Continues to Capture Market Share As of October 2008 (Peak) (~1,900 Active Rigs in U.S. Land) As of May 2014 (~1,780 Active Rigs in U.S. Land) Note: The above estimates corresponding to market share are derived from Rig Data. PDS’ market share includes both PDS and Grey Wolf rigs. Additionally, the drawworks capacity of each land rig included in the above analysis was greater than 600 horsepower.

Leading U.S. Unconventional Driller * Includes 17 announced new FlexRigs with customer commitments scheduled for delivery in fiscal 2014 and fiscal 2015. (306 H&P Contracted Land Rigs as of 5/13/14*)

Unconventional Drilling Growth in Permian Note: The above estimates are derived from Rig Data. Additionally, the drawworks capacity of each land rig included in the above analysis was greater than 600 horsepower.

H&P’s New Build Program Continues Plan to build three rigs per month through at least the remainder of the fiscal year. Flexibility to increase our production cadence and our capital spares capacity. This approach has allowed us to quickly respond to increased FlexRig demand.

Performance is Not Only About Better Rigs Our competitive advantage is also about: People Safety Experience Training Culture Support Structure Processes Organizational Network Maintenance Supply Chain
