150 ksi nickel alloy materials among new innovations for sour service

Other advances include adoption of compressive stress relaxation evaluation method and capability to use 3D printing for corrosion-resistant nickel alloys By Linda Hsieh, Editor & Publisher To reduce well completion costs in environments with H2S, Baker Hughes is working to develop innovations that span materials, manufacturing, evaluation and testing. DC recently spoke with Darren Bane, Product Line Director, about recent and upcoming technical advances for sour service. High-yield sour-service nickel alloy materials As operators continue to drill and complete wells in sour-gas environments with increasingly higher pressures and higher temperatures, the demand is also increasing for materials with higher minimum yield strengths. Over the past few decades, the highest available yield for nickel alloy materials had risen from 120 ksi ...

High-density survey data allows for capture of live inclination, azimuth, delivers clearer downhole picture

By enabling rapid assessment of wellbore trajectory, directional drillers can construct smoother well path, optimize sliding time By Chris Hartley, Gyrodata The evolution of drilling technology continues to play an important role in improving drilling efficiencies and well placement. Directional drilling providers use specialized sensors that can operate in harsh downhole environments, where temperatures reach 300°F or higher. These sensors are used to compute the orientation relative to vertical and north directions. The orientation is then used to calculate the wellbore position from the surface location to a known point along a well path, which is defined by a series of survey stations. Operators need accurate and precise measurements from drilling surveys so they can drill into the target reservoir ...
