1 MegaBits per Second and Dollars per Day: Defining the Most Cost-Effective Communications Solutions for Oil & Gas May 2013 Mike Gold VP Sales, Europe, Russia and Israel Comtech EF Data

2 Oil & Gas business environment is in a period of rapid change Depletion of older reserves Exploration & Production relies on demanding methods, such as deepwater, tight oil, and shale gas. More expensive, more complex. Alternatively, industry pursuing enhanced oil recovery from existing wells. Takes advantage of new techniques, technology, and awareness of geology of field and production history More information required and produced than ever More sophisticated technologies are producing more seismic drilling and production data These approaches depend on access to data Comtech EF Data Proprietary IDC October

4 More Data and New Technology Digital Oilfields: development and production generate large volumes of data: Acquisition, Processing and storage Chevron is growing at 2 terabytes per day; in 1997, there were only 5 terabytes for the entire company." Jay R. Pryor, VP bus. devt, Chevron Corp., 2011 Exploration uses sophisticated analytics: Seismic processing & reservoir modeling and simulation 3D used to identify new resources, 4D used to understand changes in a reservoir over time. More sophisticated technologies are producing even more data. Wide azimuth (WAZ) involves multiple ships making multiple passes to capture richer picture Produces 3x to 4x more traces per square kilometer than narrow-azimuth towed streamer (NATS) 6x to 8x data volume (IDC October 2012) Comtech EF Data Proprietary 4

7 O&G Satellite Market Oilfields, Offshore and Mobile platforms have typically relied on satellite communications Only way to reach out to remote areas and have suitable availability Energy markets are in the midst of a bandwidth revolution requiring over 25 Gbps of bandwidth by With over 461,000 In-service satellite units and $2.6B in revenues by 2022, Energy markets remain a critical consumer of satellite communications for the foreseeable future. They are key vertical across all sectors of the satellite communications industry NSR Energy Markets, 2013 Comtech EF Data Proprietary 7

8 Communications, Big Data and O&G Many of the challenges of accessing data have been overcome with faster networking technologies, but there are still input/output storage challenges such as insufficient capacity, limited upload bandwidth, and multiple access patterns IDC, Oct 2012 Several recent breakthrough in satellite communications Big Data Volume Velocity Variety Value Satellite Increased transport capacity, High Throughput Satellites, Dynamic bandwidth Low jitter/low latency, Transport of real time streaming content, Quality of user experience, Acceleration, Mobility platforms, Reliability, Guaranteed bandwidth Content agnostic QoS, application aware Comtech EF Data Proprietary 8

9 What Does it All Mean? Scotty, I need a lot more throughput but I need to minimize bandwidth! 9

10 Captain, I think I have the solution and ain t more dilithium chrystals! The Answer 10

11 TDMA Systems Won t Cut it Anymore Big Data means less opportunity to share TDMA systems have inherent overheads and latencies. The required efficiencies rely on new features that aren t available/cost effective in TDMA. 11

12 Four Pillars of Optimizing Throughput Coding Gain WAN Optimization Physical Layer Enhancements Adaptive Coding and Modulation 12

13 Coding / FEC (Forward Error Correction) Does not change your Signal to Noise ratio Does nothing to improve your signal quality FEC s simply correct errors lost in transmission But not all FECs are created equally 13

14 Coding / FEC (Forward Error Correction) Shannon-Hartley Bound: There is a maximum bound on the amount of error free data that can be transmitted though a noisy transmission medium Coding Type Sequential or Viterbi Turbo Product Codes Versa FEC DVB-S2 / DVB-S2-EB1 Vs. Shannon Bound db db db db 14

17 Four Pillars of Optimizing Throughput Coding Gain WAN Optimization Physical Layer Enhancements Adaptive Coding and Modulation 17

18 Carrier Manipulation Carrier in Carrier Use cancellation techniques in duplex circuits to take advantage of BW re-use and balance PEB Reduced Roll Off Figures (ROF) DVB-S2-EB1 Allows carriers to use more symbols in a given amount of allocated BW dscpc (Dynamic SCPC) Allows carriers to be dynamically created and sized to the remote site data demand 18

19 DoubleTalk Carrier-in-Carrier Based on patented Adaptive Cancellation, Carrierin-Carrier (CnC) allows carriers in a Duplex satellite link to occupy the same transponder space Without DoubleTalk Carrier-in-Carrier With DoubleTalk Carrier-in-Carrier Carrier-in-Carrier is a Registered Trademark of Comtech EF Data DoubleTalk is a Registered Trademark of Applied Signal Technology, Inc. 19

20 Carrier in Carrier (CnC) Advantage What type of advantage is CnC? CnC is a calculable and definitive advantage CnC is a static, unchanging advantage The advantage due to CnC will not change as conditions change Throughput increases and BW/Power savings are guaranteed for the life of the circuit What are the restrictions? Both ends of the link must be able to see their own uplink Asymmetric circuit ratios (3:1) based on Symbol Rate Power ratio limitations on TX vs. RX (+/-7 db PSD)

21 Extreme Spectral Efficiency Carrier-in-Carrier can be used to achieve extreme spectral utilization that would not otherwise be possible Best DVB-S2 Spec Efficiency = 4.45 b/hz Asia: 16APSK ¾ FEC Mbps DPLX in 15.5MHz Spectral Eff = 5.78 b/hz = 64QAM US: 32APSK ¾ FEC Mbps DPLX in 30MHz Spectral Eff = 7.24 b/hz = 256QAM THESE ARE CABLE MODEM FIGURES 21

22 Additional Roll Off Figures Roll off Figures (ROF) also referred to as alpha or α change the spectral shape of a carrier New Roll Off Figures 15%, 10%, 5% 22

23 Lower ROF Advantages What is the advantage to lower ROF figures? ROF can be used to calculate occupied BW by some satellite operators Reducing your ROF may reduce your occupied BW and thus reduce your BW payment Alternatively you can keep your occupied BW and increase your Symbol Rate What are the restrictions / drawbacks? Reducing occupied BW will reduce your available Power Equivalent BW (PEB) which reduces Es/No by about the same % as your savings in BW Keeping occupied BW and power fixed while increasing your symbol rate will lower the Es/No by about the same % as your increase in Symbol Rate Many operators may not let you use SR+ROF as occupied BW 23

24 Dynamic SCPC (dscpc) VMS provides dynamic bandwidth and carrier management Share pool(s) of bandwidth with other terminals Bandwidth can be increased or decreased on demand Lossless switching Shared Outbound BW Pools Entry Channel Comtech EF Data Proprietary 24

25 Four Pillars of Optimizing Throughput Coding Gain WAN Optimization Physical Layer Enhancements Adaptive Coding and Modulation 25

26 Adaptive Coding & Modulation (ACM) Adaptive Coding & Modulation (ACM) converts the link margin into increased capacity average throughput gain of 100% (or more) is possible, compared to traditional CCM Most of the year, the link operates at significantly increased throughput For the worst few hours of the year, the link may be available with lower throughput 26

27 ACM Concept is Simple (ACM) allows for automatic change in Modulation and Coding in response to current link conditions Symbol Rate and Transmit Power are fixed and the data rate changes as the modulation and code rate are changed ACM carriers use fixed bandwidth and power on the transponder The receiving modem in a link, provides signal quality updates to the transmit modem The transmit modem changes the Modulation and/or Code Rate to the most spectrally efficient Mod/Cod for the current conditions 27

28 Overall Link Margin ACM s value is in the conversion of Link Margin Greater the Link Margin the greater the value of ACM Most Link Margin boils down to two main factors: Link availability (99.8% vs. 99.6%) Effects of Rain Fade (Ku-Band vs. C-Band) 28
