Coastal Gas Link Pipeline (Canada)
The Coastal GasLink pipeline is a 670-kilometer (416-mile) natural gas pipeline project in British Columbia, Canada. It is being developed by TC Energy Corporation (formerly known as TransCanada Corporation). The pipeline is designed to transport natural gas from the Montney gas-producing region near Dawson Creek to the LNG Canada liquefied natural gas export facility near Kitimat on the coast of BC. The pipeline is designed to have a capacity to transport up to 2.1 billion cubic feet of natural gas per day.
Interestingly, the Montney formation is recently estimated to produce several billion cubic feet of natural gas per day, making it one of the largest and most prolific natural gas resources in Canada. In general, Montney wells are typically drilled to depths ranging from approximately 1,500 meters (4,900 feet) to 4,000 meters (13,000 feet) or more. Some wells may be drilled even deeper, particularly in areas where the formation is thicker or where operators are targeting specific zones for natural gas, oil, or natural gas liquids (NGLs) extraction.
The cost of the Coastal GasLink pipeline is expected to be around $14.5 billion — and could cost a further $1.2 billion if construction is extended into 2024, the company said in a release February 2023. TC Energy recently noted that the Coastal GasLink project safely reached mechanical completion on November 6, 2023, ahead of schedule. Mechanical completion represents another major milestone following the recent achievement of 100% pipeline installation.
Notably, the project has created 25,700 jobs, generated $3.2 billion for BC’s GDP, and $331 million in tax revenue in addition to spending $3.95 billion with B.C. businesses and suppliers, according to TC Energy’s figures. The Coastal GasLink pipeline has been subject to both support and opposition. Proponents argue that it will bring economic benefits such as job creation and revenue generation, while also providing a cleaner alternative to coal for international markets. It is also seen as a crucial component of BC's energy strategy and the broader Canadian natural gas industry.
The project has faced significant opposition from Indigenous groups, environmental activists, and some local communities. Concerns have been raised about the potential environmental impacts of the pipeline, its impact on Indigenous lands and sovereignty, and its contribution to climate change. There have been protests, legal challenges, and blockades against the project. Despite the opposition, the pipeline project is currently operational.

Directional Drilling
Directional drilling is a specialized drilling technique used in the oil and gas industry, as well as in other fields such as environmental drilling and mining. The primary purpose of directional drilling is to deviate the wellbore from the vertical position to reach specific subsurface targets or to navigate around obstacles. This technique allows for more efficient extraction of oil and gas resources and enhances the overall productivity of a well. Here are some key aspects of directional drilling:
Directional drilling has become a standard practice in the oil and gas industry, offering solutions to various drilling challenges and optimizing resource recovery. The technology and techniques involved in directional drilling continue to evolve, contributing to more efficient and sustainable energy extraction practices.
- Steering the Drill Bit:
Directional drilling involves manipulating the direction of the drill bit while drilling a well. This is achieved by using downhole tools and equipment to control the wellbore's inclination and azimuth. - Types of Directional Drilling:
Horizontal Drilling - Involves drilling horizontally once a certain depth is reached, allowing for increased contact with the reservoir and improved production rates.
Multilateral Drilling - Involves drilling multiple lateral branches from a single main wellbore. - Tools and Equipment:
Downhole Motors - These motors are placed near the drill bit and use the drilling fluid's flow to rotate the bit, allowing for directional control.
Mud Motors (Positive Displacement Motors) - These tools use the flow of drilling mud to turn a turbine, which then rotates the drill bit. - Surveying and Measurement While Drilling (MWD):
MWD Tools - Instruments are placed near the drill bit to measure parameters such as inclination, azimuth, and toolface. This data is transmitted to the surface in real-time, allowing drillers to make adjustments. - Rotary Steerable (RSS) - A rotary steerable system is a technology used in directional drilling to steer the drill bit while rotating, providing a more precise and controlled directional path. Unlike traditional methods that rely on changes in the orientation of the drill string to control direction, a rotary steerable system allows continuous rotation of the drill string, improving drilling efficiency and accuracy. Rotary steerable systems have become an integral part of modern directional drilling, offering a valuable tool for operators seeking to optimize wellbore placement and maximize hydrocarbon recovery from reservoirs. The technology continues to evolve with ongoing research and development efforts.
- Applications:
Oil and Gas Exploration - Directional drilling is commonly used in the exploration and production of hydrocarbons to access reservoirs that are not directly beneath the drilling location.
Environmental Drilling - Used to reach specific depths for soil and groundwater sampling in environmental assessment and remediation projects.
Mining - Applied in mining operations to reach and extract valuable minerals or resources. - Benefits:
Increased Reservoir Contact - Horizontal drilling allows for increased exposure to the reservoir, which can enhance production rates.
Reduced Environmental Impact - Directional drilling can minimize the surface footprint by accessing multiple reservoirs from a single drilling location.
Navigating Obstacles - Useful for avoiding geological obstacles or sensitive areas.
Directional drilling has become a standard practice in the oil and gas industry, offering solutions to various drilling challenges and optimizing resource recovery. The technology and techniques involved in directional drilling continue to evolve, contributing to more efficient and sustainable energy extraction practices.

Carbon Capture (CCS)
Carbon capture, often referred to as carbon capture and storage (CCS), is a set of technologies and processes designed to capture carbon dioxide (CO2) emissions from various sources, such as industrial facilities, power plants, and other large-scale emitters of greenhouse gases, before they are released into the atmosphere. The captured carbon dioxide is then transported and stored in geological formations deep underground, typically in depleted oil and gas reservoirs, saline aquifers, or other suitable geological formations.
The primary goal of carbon capture is to mitigate climate change by reducing the amount of CO2 released into the atmosphere, as carbon dioxide is a major greenhouse gas that contributes to global warming and climate disruption. By capturing and storing CO2 emissions, carbon capture can help industries and countries reduce their carbon footprint and meet emissions reduction targets.
The process of carbon capture typically involves the following steps:
Carbon capture and storage (CCS) has several important goals and benefits:
Examples of current carbon capture projects around the world:
Carbon capture and storage can be an important part of efforts to reduce greenhouse gas emissions, especially in industries that are difficult to decarbonize, such as cement manufacturing, steel production, and some types of power generation. However, it is not a silver bullet for addressing climate change and must be combined with other mitigation strategies, such as renewable energy adoption, energy efficiency improvements, and lifestyle changes, to achieve significant reductions in greenhouse gas emissions.
Additionally, there are technical, economic, and regulatory challenges associated with carbon capture and storage that need to be addressed for its widespread adoption and effectiveness.

By capturing and storing CO2 emissions, carbon capture can help industries and countries reduce their carbon footprint and meet emissions reduction targets.
The process of carbon capture typically involves the following steps:
- Capture - CO2 is captured from the exhaust gases of industrial processes or power plants. There are various technologies for capturing CO2, including post-combustion capture (removing CO2 from flue gas after combustion), pre-combustion capture (capturing CO2 before combustion), and oxy-fuel combustion (burning fuel in an oxygen-rich environment to produce a flue gas with a higher CO2 concentration).
- Transport - Once captured, the CO2 is transported via pipelines, trucks, or ships to the storage site.
- Storage - The captured CO2 is injected into geological formations deep underground, where it is stored securely to prevent its release into the atmosphere. Storage sites must be carefully chosen and monitored to ensure the long-term integrity of the stored CO2.
Carbon capture and storage (CCS) has several important goals and benefits:
- Emission Reduction - By capturing CO2 emissions, CCS helps reduce the release of greenhouse gases into the atmosphere, thereby mitigating climate change and global warming.
- Carbon Neutrality - CCS can be integrated into certain industries and processes to achieve carbon neutrality or negative emissions, especially in sectors where complete decarbonization is challenging.
- Stabilizing Energy Systems - CCS can help stabilize energy systems that rely on fossil fuels by capturing CO2 emissions from power plants, allowing them to continue operating while reducing their environmental impact.
- Transitioning to Clean Energy - CCS can serve as a transitional technology as societies shift toward cleaner and more sustainable energy sources.
Examples of current carbon capture projects around the world:
- Boundary Dam Carbon Capture Project (Canada) - Located in Saskatchewan, Canada, this project is associated with the Boundary Dam Power Station, a coal-fired power plant. It was one of the world's first commercial-scale carbon capture and storage (CCS) facilities. The project captures CO2 emissions and transports them to nearby oil fields for enhanced oil recovery (EOR).
- Petra Nova (USA) - Petra Nova, located near Houston, Texas, is a carbon capture project associated with the WA Parish Generating Station, a coal-fired power plant. It captures CO2 emissions and uses them for EOR in nearby oilfields. Petra Nova was one of the largest post-combustion CCS projects in the world.
- Gorgon Gas Project (Australia) - The Gorgon Gas Project is a liquefied natural gas (LNG) project in Western Australia. It includes a large-scale CCS component, which captures CO2 emissions from the natural gas production process and injects the CO2 deep underground for storage.
- Sleipner Project (Norway) - The Sleipner Project, operated by Equinor (formerly Statoil), has been in operation since the 1990s. It captures CO2 from a natural gas processing plant in the North Sea and stores it in a geological formation beneath the seabed. This project is often cited as a successful example of CCS.
- Acorn Carbon Capture and Storage Project (UK) - The Acorn project in the UK aims to develop a CCS system that can capture emissions from industrial facilities in Scotland's Grangemouth area and transport them for storage in depleted North Sea oil and gas fields. It is part of the UK's efforts to develop CCS infrastructure.

Hydraulic Fracturing (Fracking)
Fracking, short for hydraulic fracturing, is a method of extracting natural gas and oil from underground rock formations. It involves the high-pressure injection of a mixture of water, sand, and chemicals into deep underground wells to create fractures or fissures in the rock. These fractures allow the trapped natural gas or oil to flow more freely to the surface for collection.
Steps in the fracking process are as follows:
Hydraulic fracturing has been instrumental in unlocking vast reserves of natural gas and oil that were previously considered uneconomical to access. This technology has had a significant impact on the energy industry, especially in regions like the United States. However, it has also been a subject of controversy due to environmental and public health concerns. These concerns include:
The regulation of fracking varies by country and region, with some areas implementing strict controls and others allowing more permissive practices. Public opinion and government policies regarding fracking have evolved over time, reflecting ongoing debates about its benefits and potential risks.
Steps in the fracking process are as follows:
- Drilling - A well is drilled vertically into the ground until it reaches the target rock formation, which may be thousands of feet below the surface.
- Horizontal Drilling - Once the vertical well is in place, it can be turned horizontally to access a larger area of the underground rock formation.
- Fracturing Fluid Injection - A mixture of water, sand (or other proppants), and chemicals is injected into the wellbore at high pressure. This fluid, known as fracking fluid, is designed to create fractures in the rock. The water and chemicals help break apart the rock, while the sand props open these fractures, preventing them from closing completely.
- Fracture Propagation - The high-pressure fluid causes the rock to fracture, creating pathways for the trapped hydrocarbons to flow more easily. The proppants (usually sand) hold the fractures open, allowing the gas or oil to escape and migrate toward the wellbore.
- Flowback and Production - After the fracturing process is complete, the pressure is reduced, and the fracking fluid, along with released hydrocarbons, flows back to the surface. This mixture is separated, and the hydrocarbons are collected for further processing and use.
- Cost - The percentage of the completions cost that hydraulic fracturing represents can range widely, but it often accounts for a substantial portion, particularly in unconventional shale plays where extensive fracturing is required to stimulate production. In such cases, fracking costs can represent a significant majority of the total completions cost. the term "completions cost" includes all expenses associated with preparing and finishing a well for production. This includes drilling, casing, cementing, hydraulic fracturing, and other activities necessary to make the well ready for hydrocarbon extraction.
Hydraulic fracturing has been instrumental in unlocking vast reserves of natural gas and oil that were previously considered uneconomical to access. This technology has had a significant impact on the energy industry, especially in regions like the United States. However, it has also been a subject of controversy due to environmental and public health concerns. These concerns include:
- Water Contamination - There have been cases of groundwater contamination as a result of fracking operations, primarily due to the potential for leaks of fracking fluids or migration of methane gas into aquifers.
- Induced Earthquakes - Fracking can induce small earthquakes in some areas due to the injection of fluids into the ground.
- Water Usage - Fracking requires large amounts of water, which can strain local water supplies, especially in arid regions.
- Air Pollution - The equipment used in fracking can release pollutants into the air, including volatile organic compounds and methane, a potent greenhouse gas.
- Habitat Disruption - Fracking operations can disrupt local ecosystems and habitats, impacting wildlife and vegetation.
The regulation of fracking varies by country and region, with some areas implementing strict controls and others allowing more permissive practices. Public opinion and government policies regarding fracking have evolved over time, reflecting ongoing debates about its benefits and potential risks.

Liquified Natural Gas (LNG)
LNG stands for "Liquefied Natural Gas." It is natural gas that has been cooled to extremely low temperatures to convert it from a gaseous state into a liquid form for easier storage and transportation. The liquefaction process involves cooling natural gas to approximately -162 degrees Celsius (-260 degrees Fahrenheit), at which point it becomes a clear, colorless, and odorless liquid.
Key Points about LNG:
Usage for LNG:
Overall, LNG has gained increasing prominence in the global energy landscape, and the LNG industry continues to expand as countries seek to meet their energy needs while managing environmental and economic considerations.
