Drones for Surveys, Methane Detection, Reservoir Characterization, More

Drones are becoming an almost indispensable tool in the oil industry, especially when it is necessary to inspect land, equipment and infrastructure in hazardous or hard-to-access conditions. Drones are also important for safety and security because the information is quick, accurate, and can be easily archived. But, those applications tend to be in the mid-stream (transportation and processing) and downstream (refining and distribution) segments of the industry. But what about upstream, in the exploration and development phase of the industry? Drones are used extensively there as well; they are just more subtle, and they do not create such a ubiquitous presence. This presentation reviews the main applications of drones and UAV-derived information in upstream oil and gas, which includes drilling and operations, as well as using drones for outcrop studies that are then used to create more accurate geological models, and better reservoir characterization. Be sure to watch the video which also includes a review of quadcopters with the best flight time

This presentation covers some of the most quickly growing uses of drone / unmanned aerial vehicle (UAV) uses in oil and gas exploration and development:

Site surveys in tricky terrain: Building locations, determining the best places to put the equipment and all the trucks during hydraulic fracturing, as well as positioning gates, fences, and cattle guards can be significantly expedited by using drone surveys. Seismic surveys require an evaluation of the land ahead of time. Archeological and endangered species surveys are required on many federal lands.

Oil and Gas Exploration: Direct Hydrocarbon Indicators
Surface geochemistry has been used since the very beginning: the methane seeps around the Caspian Sea in Baku, Azerbaijan, were indicators of vast reserves in the subsurface; in Tulsa “Creekology” usually meant going up the creek from where you saw an oil seep.
Now, a combination of methane seep detection and airborne gravity magnetics can be used to find “pinpoint play” reservoirs, such as pinnacle reefs in Michigan or serpentine plugs in South Texas.

Fugitive Methane Emissions
Methane detection is also used to detect fugitive emissions, which create safety hazards in pipelines and facilities.

In addition, EPA and BLM regulations require monitoring and reduction of methane emissions in oil and gas operations. While it is possible to mount static methane detectors or sniffers in compressors, gas gathering systems, and pipelines, they need to be maintained each year, and also installation can be slow. If it is necessary to install several thousand of them, the time sink can be significant. So, having airborne surveys has become a popular option. In the past, helicopters were used, because the sensors were heavy. Today, there are a number of quadcopters that have methane sensors onboard. There are different types of methane sensors, which range from sniffers, laser detectors, thermal (FLIR) with infrared, to hyperspectral.

Environmental Applications
Upstream operations must concern themselves water management, site restoration, archaeological surveys, rare / endangered species surveys, floodplain management, offshore / coastal erosion, flooding, spills, fires, and monitoring. In addition, drone surveys are useful in determining volumetrics, such as the amount of water in a pond.

Constantly Evolving Technology
Quadcopters are increasing in capacity, with longer flight times and better payloads (high-definition cameras, thermal cameras (FLIR), methane sensors, and more).  The weak link continues to be the issue of battery life: the lithium batteries average 25 minutes of flight time, and then must be recharged.

Sensors are evolving rapidly, and in the case of methane sensors, there is a rivalry among them, with spectroscopy, sniffers, optical sensors, infrared, hyperspectral, laser, and more.

Drones for Better Reservoir Characterization
Digital outcrop studies are useful in and of themselves, but when integrated with subsurface data of the same formations, the resulting models are truly surprising. They can be used to characterize reservoirs, and thus predict and depict heterogeneity, facies changes, lithology, fracture networks, and faults. The information can be used to calculate porosity and permeability, as well as to predict fluid flow and reservoir conditions.

While custom drones are used, many studies use off-the-shelf quadcopters, which are surprisingly affordable and have up to 30 minutes of flight time (bring extra batteries into the field).  

The key to developing an integrated reservoir model that includes digital outcrops and other information is developing a flexible and appropriate workflow.

  • Collect traditional information (outcrop data)
  • Digitize and georeference the conventional outcrop data
  • Collect satellite and drone-derived digital images of the same location (process and georeferenced)
  • Incorporate LIDAR (process and georeferenced)
  • Incorporate still photography (process and georeferenced)
  • Integrate all the surface data
Build a model using geocellular modeling with a program such as Schlumberger’s Petrel
After the surface digital outcrop 3D model has been created, it can be possible to find the corresponding sections and sequences in the subsurface, and then to create a cross section that reflects the seismic (synthetic seismogram) that has been correlated with the petrophysical and lithological data.  Relating the digital outcrop to the digital subsurface model can result in highly detailed seismic geomorphological models that reflect structure as well as subtle stratigraphic sequences and facies changes.

Loving Canvas LMS!: New Training Courses - Collaboration & Quick-Start Guide

Many colleges, universities, and training organizations are moving away from the learning management system they have used for years and are adopting Canvas.

Canvas, which is a learning management system, can also be considered a virtual learning environment (VLE) because offers cloud-based hosting and can integrate with a number of cloud applications, such as Google applications (Docs, Drive, Sheets, Slides), Microsoft 365 applications, and media hosting (YouTube, for example). In addition, Canvas encourages webinars (live and archived) by building in Big Blue Button.

Also, Canvas offers free hosting to instructors who can create their own courses (which are, in effect, MOOCs if they catch on) and offer them through Canvas’s portal.

Canvas is not as flexible as Moodle, and it does not have as many built-in templates as Moodle’s Virtual Learning Environment competitor, MoodleCloud, but it does offer remarkable simplicity.
In addition to making collaboration very easy, the SpeedGrader function in Canvas is a huge hit with students and instructors alike.

That said, changing to a new LMS can be daunting, even if you are very familiar with Blackboard, D2L, Moodle, as well as the commercial solutions.

Easing the pain of transition was one of my main goals of putting together training courses.  I also really wanted to help unlock the joy of discovery, unleashed creativity, and productive collaboration which is possible with Canvas.

Rather counter-intuitively, I started with Collaboration with Canvas.  I wanted to help students, instructors, and administrators jump in and explore the many ways in which Canvas facilitates collaboration.

People learn from each other. Moodle has long made a discussion / forum-focused approach the cornerstone of connectivist / connectionist learning theory.  Canvas embraces this approach, as people can easily share and collaborate on documents and presentations in order to create group projects and portfolios.  Also, Canvas makes it possible to use the discussion board as a blog and to subscribe to it via RSS feed.

Canvas for Collatoration
Canvas for Collaboraiton
 At any rate, I explored these and many other ways to collaborate in Canvas for Collaboration, which is a 6-unit, 30 module course:
  • How Canvas works for many different applications
  • Canvas and collaborative activities for academic applications
  • Group editing best practices
  • Using Canvas for event planning
  • Using Canvas for building a product with distributed team members
  • How to collaborate to demonstrate learning goals and compliance
  • How to assess the end products of collaborations
  • Collaborating using different types of media
  • Compliance training
Quick Start Guide for Collaboration
Quick-Start Guide for Canvas
Then, I backed up a bit and created a 6-unit, 30 module course on getting started in Canvas. Entitled Quick Start Guide for Courses in Canvas,, the objective is to provide all you need to create great courses in Canvas.

This course is a practical guide filled with examples. It covers the basic and advanced concepts of Canvas. Every recipe is as simple as possible without compromising creativity.

In this course, you can
  • See the best way to plan and design an online course
  • Discover the unique features of Canvas and how to use them
  • Get to know the best way to organize content
  • Understand how to incorporate multimedia
  • Know how to use Canvas’ social media features
  • Make sure that students achieve their learning goals and objectives
  • See different forms of assessment in Canvas
  • Use Canvas’ features to motivate and encourage students
I truly enjoyed creating the courses, and I hope that taking them and participating in them is as enjoyable for the learner.

Some of Today’s Most Profitable Quadcopter Drone Uses

Drones, in particular, quadcopters, are quickly becoming the standard way to obtain high-quality images and other data for areas that have been hard or expensive to access. There are many quadcopter on the market, and their capabilities are unfolding rapidly, and companies such as WingsLand offer a wide array of capabilities, ranging from a mini-quadcopter that can fold up and fit in one's pocket, to larger drones capable of longer flight times (check out Drones for Sale).

Small drone services providers maintain at least four drones to assure there are sufficient back-ups and also redundancy in order to cover more than one job at the same time.  Technology is changing so quickly that it’s a good idea to have a plan for quick payout of the drone (along with the cameras and sensors), along with software licenses and cloud-based storage so that you can plan to upgrade your equipment and maintain a high-quality product.

It is important to keep in mind that FAA regulations still involve a number of restrictions, and it is illegal to fly near airports, over stadiums, and in cities. There are also a number of privacy and security issues which must be considered when developing the flight plan and workflow.

You also need to have a good idea of the flight time for your drone. Which are the drones that have the longest flight time, and what payload can they carry? You must investigate this aspect very carefully. Here is a link to the longest flight time drone and others.

Photography and 3D Imaging

Real Estate:  Drone photography is used in many ways in real estate, including surveys, sales and in evaluation of projects.  In addition, drone photography is used in conducting inspections of the structures as well as the grounds.
Sales and Surveys
High-end residential
Commercial buildings, especially for planning renovations
Reconnaissance / Opportunities assessment, especially in rural or coastal areas
Acreage / ranches / development
Commercial buildings: fa├žade, windows, roof

DJI Phantom 5:  Built-in camera, easy to get started.

Events:  Drones are often used at weddings, festivals, sporting events, but the usage must be carefully planned in order to avoid legal issues. First and foremost are safety and privacy issues.  It is important to obtain signed releases from the people who will be photographed.

Natural Disasters:  Drones are extremely useful in determining the scope and impact of a natural disaster, and can be extremely helpful in identifying impassible infrastructure. They are also used in search and rescue operations, and can help identify the direction of quickly moving wildfires. Drones used are often equipped with infrared / FLIR sensors as well as high-resolution cameras.

Inspections: Equipment / Operations:  In addition to real estate inspections, drones are being used to inspect inaccessible locations and ones requiring 3D visualization.
Insurance companies: Buildings, infrastructure
Solar panel inspections
Wind turbine inspections

Infrared / FLIR / Multispectral Sensors

In addition to high-resolution photography, using sensors that allow you to detect thermal variations can help you generate false color composites from which you can extract a great deal of very useful information. Here are some of the most popular uses. It is usually a good idea to combine multispectral images with photogrammetry. 

The FLIR Duo is a new product that combines thermal and visible light imaging and has been designed for drones.  FLIR is a leader in thermal imaging, both for professional and personal use. 

Watch video:

  • Agricultural: Precision agriculture; monitoring crop health and irrigation needs.
  • Security and Surveillance:  These sensors pick up heat sources, which include bodies – human, animal, or otherwise.
  • Environmental:  Determining coastal erosion, chemical spills, the depth of water bodies, and distressed vegetation.    
  • Herd Tracking (Commercial and Feral): Have a feral hog problem? Are deer eating your favorite bushes? Drones, combined with fixed surveillance cameras / sensors can help you identify the nature of your intruders.  
  • Leak detection in buildings: Thermal signatures are used to pinpoint leaks in roofs and other structures.
  • Hydrothermal resources / hot springs (and possible affiliated mineralization): Thermal anomalies are used in identifying geothermal resources and also places with possible mineralization due to the action of hot, mineral-saturated waters. 
  • Search and Rescue:  Heat signatures can help identify individuals needing to be rescued, especially at night. 
Fugitive Gas Emissions / Hyperspectral
Hyperspectral and multispectral sensors are being used to detect fugitive methane from operations and also natural gas seeps. The process is used for methane leak detection as well as identifying possible areas where oil and gas may be found in commercial quantities.

The Future
As the equipment and sensors improve, the cloud-based 3D imaging will also improve. The spoils are for the innovative, creative, and those who clearly identify the problems that are best solved by means of drones. Of course, drones will generate their own unintended issues -- but a problem is always another opportunity.
