Did you know that accountants were hesitant to adopt spreadsheet programs like excel? Or that it took us decades to fully adopt trains, automobiles and computers? Do you think these things changed our lives? Of course! How could we conceive where we are today without them? But it took a while for them to gain “steam” (pun intended).
The situation with the Digital Oilfield in North America follows these familiar lines. It is a transformation that I cannot adequately explain since I only know how to build the enabling technology. How it’s going to be used is up to each person acting individually and resulting in a collective connected effect. Sure, I can give some examples or find people who have done this or that. But that’s the tip of the iceberg. The “killer example” is going to be different for every team in an energy company.
The enabling technology for the Digital Oilfield is called a “Connected Field”. It takes the Oilfield improvement areas listed below and binds them together. It’s the enablement of seamless intercommunication and coordination that truly leverages a Digital Oilfield. Without it, it’s an Oilfield that uses new Oilfield technology – not the exciting “Digital Oilfield” that truly propels the energy business to the next level.
There are so many ways to get a Connected Field wrong for a Digital Oilfield. Even with the right telecom vendors, it’s so easy to say “we don’t need QoS (Quality of Service)” – simply because the decision maker doesn’t know what it is. The fallacy is that there is a belief we already have a Digital Oilfield. There are already real world examples of a true Digital Oilfield using a Connected Field. And they are all in the Middle East; lowering their costs and increasing their supply. I cover a real world example later, so it will be easy to see the difference.
But let’s go back to the beginning. What is a “Digital Oilfield”? The concept was first presented in the seminal study: “The Digital Oilfield of the Future: Enabling Next Generation Reservoir Performance”, IHS Cambridge Energy Research Associates, Inc., 2003.
A Digital Oilfield makes the following improvements to the Oil & Gas business – and a Connected Field enables most of them; that is, you need a connected field to truly leverage the benefit to the full extent.
So what is a “connected field”? It is a data communications system that has these characteristics:
- Completely and seamlessly covers the area of interest (like cellular data might cover all of the downtown of a city). This allows users to just turn on a device (sensor, video, etc.) reducing or eliminating the need to involve IT to justify a business case to obtain capital to expand the network. It just works. Technicians are not required to tune antennas at the user level. A rig can just move itself and still have full connectivity to all its services while it is moving and when it reaches its destination.
- It is a committed That is, it is not a “best effort” network, shared with other companies and people in the area (like cellular data).
- It allows full control – that is, it has quality of service (QoS) capabilities to prioritize business critical applications or applications requiring better service to function correctly (voice, video).
Let’s examine what is not a connected field:
- Cellular data from any major telco. The reason why it is not is that it has no QoS and is best effort (no committed bandwidth) and may not cover the entire field without boosters (which are technically illegal according to the Telecommunications Act).
- MPLS networks – in themselves, they would help if the purchaser buys QoS. If the cost of buying the right networks with QoS was used to price the rent option, it is likely that the system could be built from scratch less expensively. That is, a Digital Oilfield should consider the “rent vs buy” options like any procurement decision.
- Satellite – the price per Mbps with QoS and dedicated bandwidth is horrendously expensive. Unless the company (including all teams and phases that work in the area) only expects to operate in the area for 6 months or less, it’s frequently the case that it is cheaper to build.
- SCADA (legacy 450 & 900Mhz) – really this is only for “tin can on a string” SCADA data – that is monitoring / telemetry. There are now new SCADA radios that can supply QoS and bandwidth rates at 18Mbps or above but most Oil & Gas companies, especially in North America are not using them. Most of the SCADA radios in use today use technology that was developed during World War II and they have not been updated. We’re talking punch card era technology.
And of course, I hear all the skeptics. So what does a Digital Oilfield do in practice? Here’s an example:
Petroleum Development Oman (PDO)
- Connected field coverage: 45,000 sq. km (17,000 sq. miles)
- Increased a mature (brownfield) oilfield’s production by 100K barrels/day. At $90/barrel this is $3.2 Billion/year in additional revenue within one year. (Ok, yes, price of oil… but this was done in 2012 – even at $30 that’s $1 Billion)
- Reduced drilling & completion days to online from 39 days to 14 days ($1M per drill saved). Including completions, saved $5M per well.
- 10 month payback.
What does the Connected Field network look like for PDO?
As of the end of 2013, Petroleum Development Oman field has:
- 6600 broadband connection points
- 52 base stations
- 13 Gbps total capacity, the equivalent of 500 connected homes or the bandwidth provided to a 4000 person office building
- 130,000 end devices
Compare this to a field of that size in North America; there are maybe 10 cellular base stations covering the entire thing. Everything overloaded to the point that it does not work that well (e.g. “worse than dialup” is what I frequently hear).
Together the Connected Field collects 36 times more data enabling more accurate and improved decisions. It delivers 4 Mbps anywhere within the field of coverage (compared to less than 300kbps in some fields available today). You can drive around in a truck all day long and everything just works.
No messing with devices, changing networks, etc. Need to talk to the engineer in head office and start a video chat about a valve to show him/her the valve? Done! No problems. Want to implement an intelligent video system to monitor the flare stack, look for pipeline leaks, identify personnel not wearing PPE, etc.? Want a “mobile worker”? (Please do not confuse it with a “mobile OS” which is simply an operating system built to enable mobile workers that have a network.) With a Connected Field, you just do it! No need to price in a brand new network to enable the business case.
The cost of all this? Less than 1% of the total injected capital into a greenfield area. And if a true connected field is implemented that is multi-use and multi-team capable, the expenditure is less than what they spend today.
Despite the impressive track record how many Digital Oilfields are there in North America? None. Some are close with partial implementations but it’s localised and not well championed at the executive and board levels. How many in the Middle East? Quite a few. Middle East operations have the direct support of the board of directors/families and executives. Would this situation have any bearing on the current supply / demand and geopolitical climate? Hmm….
