A new method for survey design overcomes repeatability issues.
Always on the lookout for new technology that improves efficiency, increases safety and lower costs, one Chinese oilfield operator found a solution by drillling the top section of wells with a casing drilling system.
A new generation of solid tubular expandable liners provides dependable results even when conditions are deemed high risk.
Expandable technology enables improved efficiency and economics in well remediation and sidetrack projects.
Solid expandable technology, expandable casing patch systems, and expandable liner hangers enable many new techniques for drilling and completion operations.
Low-frequency passive seismic can go where conventional seismic often can’t and can provide a clearer indication of hydrocarbon
Offshore opportunities abound from Benin to Sierra Leone.
Chevron overcomes file size limitations to deploy satellite images in mobile field mapping projects.
A new dilute chemical method can recover more than half of the oil left in depleted, fractured, oil-wet carbonate reservoirs at a chemical cost of less than US $1/bbl of oil. The process depends on compressing the gas in depleted reservoirs by injecting dilute (< 0.1 wt%) surfactant alkaline solutions, altering the wettability, and producing the oil by wettability alteration.
The current price regime of crude makes it imperative that CO2 flooding scoping models account for the extra gas processing expense that comes with increased gas handling volumes and the additional revenue that comes from the highly profitable natural gas liquid (NGL) stream.
Optimizing reservoir management, re-building surface facilities, and infill drilling result in a substantial increase in the value of a field producing for almost 60 years.
Although contaminated gas makes up a small amount of the world’s reserves, those reserves are becoming increasingly important to international oil companies (IOCs). National oil companies (NOCs) are capitalizing on easier-to-produce sweet gas reserves and leaving the more difficult contaminated reservoirs for the IOCs.
The Cherokee Basin is emerging as a significant coalbed methane (CBM) play.
A proposed method reduces total dissolved solids in produced water.
Complete metal fatigue or even wear before complete failure can be continuously measured using the technology of harmonic footprinting.
Joints make the system react to the applied environmental loads in a fundamentally different manner compared to the performance of single hull floaters.
Shell applies a suite of advanced technologies to develop a challenging project offshore Brazil.
Increased oil recovery (IOR) screening of the fractured Mogollón Formation in northwestern Peru has led to a plan that will increase recovery and has targeted areas for additional study.
Faced with developing a tough, multizone reservoir in Ecuador, an innovative combination of real-time images was used to make proactive geosteering decisions.
Dr. Armando Zamora, director general of Agencia Nacional de Hidrocarburos (ANH), Colombia’s national hydrocarbons agency, outlined the country’s plans for the upcoming bidding round and the efforts being made to differentiate Colombia as a favorable place for international investors.
