Shale Oil Providing Growth Opportunities in NuStar’s Transportation Segment

• A key strategic objective is to grow earnings from fee-based logistics services

— Redeploying existing and/or building new pipelines and terminals in the shale oil regions

— Diversifying customer base and expanding logistics services for crude oil, condensate and natural gas liquids through asset modifications, expansions and strategic

acquisitions • Majority of internal growth capital will be spent on shale pipeline projects

• Tremendous opportunities for growth in our own backyard

• To date NuStar has completed five internal growth projects in the Eagle Ford Shale

region with additional projects forthcoming

Internal Growth Project #4: Connection of 16” Corpus to Three Rivers Pipeline

to TexStar Pipeline System • TexStar Midstream services constructed a 65-mile, 12-inch pipeline that can transport 100 thousand barrels per day of

crude and condensate from Frio, McMullen and La Salle Counties, Texas to Three Rivers, Texas • TexStar pipeline is interconnected to a new storage facility constructed at Three Rivers, Texas by NuStar

– Storage facility comprised of three 200 thousand barrel storage tanks • Storage facility connected to NuStar’s existing 16-inch pipeline that can transport up to 240 thousand barrels per day to

NuStar’s Corpus Christi North Beach storage terminal • Connection and storage facility completed in 4th quarter 2012

Internal Growth Project #5: Pawnee Pipeline Further Expands Capacity for Shipper

in Eastern Portion of Eagle Ford • NuStar completed construction on a 100 thousand barrel terminal facility, truck offloading facilities and a pipeline

connection to NuStar’s existing 12” Pettus line for ConocoPhillips – 12” Pettus line is connected to NuStar’s Three Rivers to Corpus 16” line giving shippers the ability to move Eagle

Ford production to Corpus Christi • Dock expansion at Corpus Christi North Beach Terminal will give ConocoPhillips and other customers more options to

move Eagle Ford crude – Projected completion in the 2nd quarter of 2014

December 2012 Crude Oil Pipeline Acquisition from TexStar

• In December 2012, NuStar acquired TexStar’s 140 miles of crude oil transmission and gathering lines as well as five storage terminals for $325 million

• Provides Eagle Ford Shale region crude oil producers the ability to move production to Corpus Christi – Crude oil producers have access to NuStar’s Corpus Christi storage and dock space that can be utilized for shipments to

other markets • Currently shipping around near capacity and have active open season to secure commitments to expand

the system

8

Open Season for South Texas Crude Oil Pipeline System Project • South Texas Open Season commenced July 17, 2013 and ends September 30, 2013 • Assessing shipper interest in committed space to transport Eagle Ford Shale crude oil from several terminal

locations on our South Texas Crude Oil Pipeline System to our Corpus Christi North beach facility • Proposed project includes pipeline capacity upgrades to segments of our South Texas Crude Oil Pipeline System • Total incremental capacity of 100,000 barrels per day would occur in two phases:

– First phase would add incremental throughput capacity of approximately 35,000 barrels per day and should be available for service in the third quarter of 2014

– Second phase would add incremental throughput capacity of approximately 65,000 barrels per day and should be available for service in the first quarter of 2015

NuStar’s Throughputs in the Eagle Ford Shale Expected to Increase

Eagle Ford Shale a Transformative Economic Impact for Texas but has Resulted in Transportation Challenges

• Production in the Eagle Ford Shale continues to increase and will exceed 1 million barrels per day by the end of 2013

• As producers better understand the formations in their drilling programs, efficiencies are emerging, allowing more wells to be drilled with fewer rigs

• Advantages for the Eagle Ford Shale producers is close proximity to US Gulf Coast refineries and greater infrastructure

• Most crude oil imports came to the US Gulf Coast and supplied Gulf Coast and mid-continent refineries; now flow is reversed

– Growth in U.S. light oil production, particularly from the Williston, Eagle Ford and Permian, has displaced an increasing amount of imported light oil

• Much greater volumes of shale oil have overwhelmed transportation and storage infrastructure, however, numerous large-diameter pipeline projects completed and underway

• Current takeaway capacity expected to be approximately 1.6 million barrels per day, which will equate to production estimates by 2018

• Customer interest is driving continued takeaway capacity – Customers want optionality and capacity for growth in areas served by NuStar

• Continued production growth in oil window as producers become more efficient and drill to hold acreage

Current Eagle Ford Constraints and Issues

• Competition of Eagle Ford Barrel with Cushing/Permian Barrel – Eagle Ford crude oil will compete directly with Cushing/Permian Basin barrels in the

Houston/Port Arthur Area – Additional Corpus Christi Waterborne shipments will help Eagle Ford crude avoid the

Cushing/Permian crude oil competition and reach better markets – Will crude oil distribution system build outs in Houston take some Eagle Ford off the

water

• Quality of Blended Crude – Continue to see substantial variability in quality – Producers and refineries desire to maintain quality and value of Eagle Ford Shale barrel

through segregation – How does quality drive destination choices?

• Market for High Gravity Crude Oil

– Significant amount of high gravity barrels headed our way – will condensate splitters and export capabilities as well as topping units be enough to absorb supply?

• Will the Success of the Eagle Ford Drive Midstream Companies and

Producers to View Infrastructure Commitments Differently?
