Climate science tells us that if global average temperatures rise more than 1.5°C above pre-industrial levels, the impact could become catastrophic and irreversible.   In the oil and gas industry, we are all aware of the very real impact the climate crisis is having on society and the planet. Whilst we provide energy for the world to prosper, the way most of this energy is produced as well as consumed, is ultimately leading to climate change.   Whilst we continue to develop clean energy solutions, the reality is that ~56% of the global energy mix continues to come from hydrocarbons, and it will take years, if not decades, before the balance shifts to cleaner sources.

Water managementWater management Overview Resource management Improve injection performance Reduce water production Go to section OverviewResource managementImprove injection performanceReduce water production Home Search Results Water is a precious natural resource that is used prolifically by the industry for a wide range of purposes, such as drilling, reservoir injection, cementing and hydraulic fracturing.Improve natural resource management Water is a precious natural resource that is used prolifically by the industry for a wide range of purposes, such as drilling, reservoir injection, cementing and hydraulic fracturing. Water can come from recycled sources, but in some areas it is sourced from natural aquifers or the oceans, and this can cause an ecological imbalance. It’s important that water is used sparingly and efficiently.   Apart from the large amounts of water used for injection, hydraulic fracturing and chemical also needs huge amounts of water to be effective. TGT has developed two specific answer products in our True Flow range that help operators assess the effectiveness of fracturing and stimulation operations—Fracture Flow and Stimulate Flow. These surveys can be deployed pre- and post-operations to help optimise fracturing and stimulation programmes, and potentially reduce associated water usage. RESERVOIR FLOW CASE STUDY A typical hydraulic fracturing job uses 5-10 million gallons of water per well. Improve injection performance Most oil reservoirs will inevitably require additional pressure support to maintain production and improve oil recovery. Water injection is used widely for this purpose and many oilfields are injected with tens to hundreds of thousands of barrels per day. Pumping water is energy intensive and the resulting CO2 emissions can range from 1-2 kgCO2 per barrel. In fact, water injection is responsible for ~40% of total CO2 emissions for a typical oilfield.   Making matters worse, well completion and formation integrity issues can lead to water being diverted away from the target reservoir. This can result in abnormally high injection rates, reduced field production performance, and high water cut in producer wells. TGT’s True Flow products are being used globally by operators to ensure that all injected water is reaching the target and revealing where it is not. In many cases, these diagnostics lead to a significant reduction in water volumes and CO2 emissions, and increased field production. RESERVOIR FLOW CASE STUDYFIBRE FLOW CASE STUDY Pumping 10,000 barrels of water per day produces 5.4 ktCO2 annually. Reduce water production High water cut is a persistent industry challenge responsible for unnecessarily high CO2 emissions and higher carbon per barrel. Excess water needs to be managed at surface, treated then reinjected or disposed of, and this requires energy. Also, excess water often means less oil, reduced recovery and longer production times, increasing emissions even further. And complicating the issue, produced water may be channeling from several elusive sources hidden behind the casing.   In many cases, excess water cut can be minimised or cured. If the operator can identify the true source of water downhole, measures can be taken to shut-off the water and restore oil production to lower carbon and economic levels. TGT’s True Flow products are used widely for this purpose. Unlike conventional diagnostics that can only detect water entering the wellbore, TGT’s through-barrier diagnostics can reveal the true source behind casing, enabling effective remediation, improved recovery rates and reduced carbon emissions.

Methane emissionsMethane emissions Overview Stop methane venting Secure abandoned wells Emissions Go to section OverviewStop methane ventingSecure abandoned wellsEmissions Home Search Results Oil and gas producers vent leaked methane from casing cavities to reduce pressure. TGT’s diagnostics can locate the source and flowpaths of rogue gas leaks, ensuring they can be sealed, thereby reducing the need to vent.Stop methane venting Sustained annulus pressure (SAP/SCP) is caused by a build-up of fugitive fluids such as gas in the annular spaces surrounding well system casings. The casings are designed to withstand high pressure but if this pressure is reached, the gas is diverted to the production stream or vented to atmosphere. The global warming potential of methane is ~80x that of CO2, so even small amounts are damaging and must be contained.   These rogue fluids reach the annulus via seal failures and flowpaths that begin at hydrocarbon-charged formations and continue towards surface causing a build-up of annulus pressure. TGT’s True Flow and Seal Integrity products can locate the source of annular fluids and trace the flowpaths, enabling well operators to target effective repairs and eliminate SAP-related methane venting. Methane has 85x higher global warming potential than CO2. Secure orphan and abandoned wells Orphan wells typically have no legal owner and may have been abandoned without undergoing a proper decommissioning or plugging process. Methane or liquid emissions from orphan wells can be significant contaminants, especially when the number of orphan or incorrectly decommissioned wells is thought to be in the millions globally. The burden of responsibility for these wells typically falls with operators, regulators or local government, and permanently sealing them is a top priority.   Validating well barrier status and revealing emission sources downhole inside the well system is the first step in sealing these wells properly. TGT’s Seal Integrity and Tube Integrity surveys are used to achieve exactly that. Precision diagnostic insights inform and guide the decommissioning agent to design and execute an effective plugging programme. This approach is equally applicable for any well decommissioning operation, not just for orphan wells, helping operators to secure them efficiently and cost effectively. Regulators estimate >3.5 million abandoned wells in US emit 7.1 mtCO2e annually. Reduce fugitive emissions Well systems are designed to connect high-pressure oil or gas in deep underground reservoirs to surface flowlines securely with full containment. Rigorous industry standards necessitate the presence of at least two ‘integrity barriers’ between produced fluids and the environment outside of the well system. Occasionally, one or more barriers can fail allowing fluids to escape, sometimes with dire consequences.   Apart from the major oil leaks that make headlines, some smaller oil and gas leaks can continue undetected for years, especially if they are hidden underground or migrate far from the well system. TGT’s Seal Integrity products are designed to locate even the smallest seal failure anywhere within the well system, enabling precise targeted repair. Used proactively, the same diagnostics can be used routinely to ensure well barriers are intact at all times, reducing fugitive emissions.
