When oil and gas operators need to carry out workovers or plug and abandon a deepwater well, a primary concern is how much fatigue life remains in the wellhead.Wells from two decades ago were drilled and completed with rigs that may have been decommissioned…
Even with the best seismic data and reservoir modeling available, drillers have remained in the dark about what’s in front of the drill bit. A new sensing tool has been designed to “see” ahead of the bit and can transmit data in real time to shift drilling operations from reactive to proactive…
While operators are in the business of producing oil and gas, their wells eventually produce sand. In addition to constricting the well’s oil and gas output, sand that reaches the topsides can damage critical equipment.Preventing sand production through completions is critical…
The oil industry has a host of methods for keeping hydrocarbons moving smoothly through flowlines, depending on what might restrict production.Hydrates, or ice-like solids resulting from the combination of free water and natural gas at high pressure and low temperature…
As oil and gas wellbores age, owners need new and better ways to gather – and understand – intelligence about the condition of their assets.Downhole cameras can be useful for finding restrictions in a wellbore during completions, and they can…
Halliburton leveraged technology from the mining industry to reveal subsurface structures in a way that improves geosteering, geomapping and geostopping in complex reservoirs.The service company has introduced EarthStar 3D Inversion, a 3D reservoir mapping process that…
In an industry with infrastructure well beyond its design life, stock sharing for replacement parts can help keep equipment running smoothly.Because maintenance is critical for safe and continued operations, asset owners tend to keep plenty of spare parts on hand…
A technology used in security and drug enforcement was modified to solve the age-old problem of how to use radiography for non-destructive testing of pipelines on rigs without affecting nucleonic measurement associated with pressure vessels…
Expandable liner hanger designs are advancing to meet the ever-increasing demands of deepwater well construction.A new expandable liner hanger design provides an effective liner top seal for high-pressure, high-temperature (HPHT) well conditions…
Changing environmental regulations around the world will have an impact on how the offshore industry handles produced water.Typically, offshore operators treat their produced water so it can be discharged back into the ocean, although there…
An industry that operates in some of the harshest environments in the world sometimes needs to call on the toughest material for wear parts.Enter the industrial diamond, discovered in the 1950s. Synthetic diamondcan tolerate abrasive, high-temperature…
Chevron is combining technology and streamlined work processes to maximize production efficiencies in its mature offshore fields. Continued investments in the fields, reservoir surveillance, analytics and portfolio optimization are some of the…
After a tough handful of years with an oversupplied offshore supply vessel (OSV) market, OSV companies may be finding the tide is finally turning.At the peak of the last upturn, OSV companies were ordering newbuilds to meet projected demand…
Deepwater drilling activities require contingencies for temporary abandonment of the well, sometimes necessitated by wellhead change outs or riser work, and sometimes by Mother Nature.Existing mechanical solutions can struggle with restrictions inside the riser or seabed structure…
IBM’s The Weather Company has predicted a slight decrease in the 2019 Atlantic hurricane season compared to 2018, but el Niño’s delayed advance could increase this year’s storm potential.The Atlantic hurricane season starts June 1 and runs through November 30…
