  • Flaring

    FlaringFlaring Overview Reduce flaring Go to section OverviewReduce flaring Home Search Results Gas flaring contributes significantly to upstream sector emissions. TGT’s diagnostics locate the source of unwanted gas enabling it to be sealed off, thereby reducing the need to flare.Reduce flaring At an estimated 310 MtCO2, routine and non-routine gas flaring is one of the largest and most pervasive sources of upstream CO2, accounting for ~30% of all upstream emissions globally. During oil production, associated gas is produced from the reservoir together with the oil. Much of this gas is utilised, but excess gas is flared because of technical, regulatory, or economic constraints. Understanding the source is a key step in minimising the flaring of excess gas.   If unwanted gas is produced unexpectedly from targeted or non-targeted formation layers, it may be possible to shut this off if the source can be precisely located. Conventional well diagnostics can locate where gas is entering the wellbore, but not always the true source. TGT’s True Flow and Seal Integrity products can identify the primary source and pathways of unwanted gas from formations beyond the wellbore, even behind casing. This can lead the way to stopping the gas and its associated flaring. Flaring is responsible for more than 30% of all upstream CO2 emissions.

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.

  • Energy and resource efficiency

    Energy and resource efficiencyEnergy and resource efficiency Overview Infrastructure performance Intervention efficiency Improve injection performance Reduce water production Go to section OverviewInfrastructure performanceIntervention efficiencyImprove injection performance Reduce water production Home Search Results Producing hydrocarbons requires energy. Turbines and diesel generators account for 70% of upstream CO2 emissions. Our diagnostics can help you become more energy efficient and reduce your carbon overhead.Improve infrastructure performance Building and operating hydrocarbon extraction infrastructure represents a huge investment in energy, capital, time, materials and people resources. Maximising the return on that resource must be achieved, while protecting people and the planet. If a well or reservoir is not producing to its full potential during its life then the resource that built or operates it is not being fully leveraged and some is being wasted. Equally, if maintenance and workover resources are being utilised, they should operate efficiently and contribute to overall asset performance with the goal of keeping wells safe, clean and productive.   All TGT diagnostic products are adept at revealing inefficiencies and guiding measures that enable existing infrastructure and resources to operate at maximum efficiency. For example, if a well is producing at high water cut, our Total Flow product will reveal the exact sources of water to enable targeted remediation. True Integrity products can be used proactively to identify casing weakness before the casing fails, helping to maintain asset performance and preventing more costly scenarios. Equally, because workover and rig resources are better targeted, time and energy is saved in getting the job done right first time. TOTAL FLOW CASE STUDYPRIMARY SEAL INTEGRITY CASE STUDY Drilling a single deepwater well can produce more than 20 ktCO2 Improve intervention efficiency Well delivery and intervention operations such as drilling, fracking, workovers, decommissioning [P&A] and diagnostic surveys require energy intensive surface equipment. Rigs, trucks, and pumps derive power from diesel engines or gas turbines that emit CO2 when the fuel is burned. A typical semi-submersible drilling rig emits roughly ~130 tCO2 per day and a Light Well Intervention vessel around 30 tCO2 per day. Improving efficiency and minimising the time to perform operations is a key factor in reducing energy consumption and emissions.   All TGT diagnostic products deliver insights that enable all types of operations to be carefully planned and precisely targeted so they can be executed efficiently with precision. Also, by enabling ‘lighter’ or ‘rigless’ interventions, our diagnostics can be deployed with minimal carbon footprint before heavier equipment is mobilised. Lastly, because through-barrier diagnostics provide a more complete picture, we provide maximum information in the minimum amount of time. Time savings translate to both cost and carbon savings and our aim is make every hour count. MULTI TUBE INTEGRITY CASE STUDY A typical Jack-up rig emits 70 tCO2 per day.

  • Enabling cleaner energy

    Enabling cleaner energyEnabling cleaner energy Overview Secure gas storage Go to section OverviewSecure gas storage Home Search Results To reduce carbon emissions, society needs to switch from fossil fuel energy to alternatives. However, non-fossil sources only satisfy 17% of the world’s energy demands. As a transition fuel, gas offers a cleaner alternative to coal, provided it doesn’t leak from infrastructure.Secure gas storage To reduce greenhouse gas emissions, society needs to switch from fossil fuel energy to alternative forms. In 2020, only 17% of the world’s energy came from non-fossil sources, 31% came from oil, 25% from gas, and 27% from coal. At 56% of the energy mix, oil and gas are still essential. Whilst oil and coal use are in decline, gas use is trending up.   Gas is the cleanest burning fossil fuel, but with the increase in use comes the risk of methane leaks in production and storage wells. Since methane is 85x more potent as a greenhouse gas than CO2, the integrity of producing and storage wells is essential in enabling cleaner energy solutions. Used proactively, TGT’s True Integrity diagnostics can be used routinely to validate seals in gas producing and storage wells, and assure methane containment. Burning 1kg methane produces twice the energy and half the CO2 than 1kg coal

    #TechTalk Series 1 – Watch again

    Did you miss out? In our first series of #TechTalks, we revealed a range of powerful well system diagnostics that would help you to maintain safe, clean and productive well operations.   They were 40-minute sessions, with Q&A sessions interspersed.  The sessions were free to attend.   If you missed the sessions, they are available to watch again by clicking the links below. The series was a resounding success, so have planned a second series covering different topics. To find out more click here. #TechTalk No.1 – Well decommissioning Improving P&A economics and performance, featuring True Integrity   The industry is expected to spend more than $40-billion on oil & gas decommissioning projects between now and 2024 according to a study by Rystad Energy. It is expected that if low oil prices don’t bounce back soon, aging wells that are no longer commercially viable could be decommissioned.   Operators are bound by strict regulations, to ensure the integrity of the well prior to abandonment. In this #techtalk we discussed a new approach to P&A. An approach that uses powerful diagnostics to significantly improve the economics and performance of P&A projects. #TechTalk No.1 - Well decommissioningDOWNLOAD PRESENTATION #TechTalk No.2 – Seal integrity Ensuring your well is safe, clean and productive, featuring Multi Seal Integrity   Well integrity and productivity depend on the performance of many barriers and seals, and a single breach can undermine the entire system. Some breaches can be easy to spot but others are more challenging. In the current economic climate, targeted remediation is essential to reduce intervention time and costs; this is only possible with accurate and comprehensive diagnostics.   In this #techtalk, we delved into four challenging scenarios: unwanted flowpaths, unknown cause of Sustained Annulus Pressure, micro-leaks and a gas storage reservoir flowing into other formations. We revealed how our through-barrier diagnostics can be applied to validate seal performance for better remediation decisions. #TechTalk No.2 - Seal IntegrityDOWNLOAD PRESENTATION #TechTalk No.3 – Sand production New diagnostics for sand management, featuring Sand Flow   Sand production is a serious issue that can impact productivity and asset integrity. For many years, the industry has searched for a reliable technique to locate and quantify sand entry to the wellbore, but with mixed results. Until now.   In this #techtalk we uncover a new robust diagnostic product that precisely locates and quantifies the dynamics of sand production downhole. #TechTalk No.3 - Sand productionDOWNLOAD PRESENTATION
