Single-trip stand-alone screens cut rig time, costs in deepwater Nigeria

Shell worked with service providers to develop new completions concept resulting in significant savings on Bonga field By Jessica Whiteside, Contributor Why do in two trips what you can do in one? That simple concept forms the foundation for a revolutionary, high-tech approach to deepwater stand-alone screens completion tested at Shell’s Bonga operations off the Nigerian coast. The project team described the evolution of the single-trip pilot in a presentation at the 2019 Offshore Technology Conference (OTC) in Houston on 9 May. The Bonga field was Nigeria’s first deepwater oil discovery and boosted the country’s capacity by 10% when it launched production in 2005. Shell’s pursuit of the world’s first single-trip completion for deepwater, open-hole, stand-alone screens (SAS) in the ...

Sales of zonal isolation packers surge with resurgence of well drilling operations

According to a recent study from Fact.MR, sales of zonal isolation packers exceeded 25,438 units in 2018 and are estimated to surpass 26,000 units in 2019. The study found an increasing need from operators to address the issue of gas migration, which continues to be one of the longstanding challenges requiring immediate attention. This, in turn, is paving favorable grounds for adoption of effective zonal isolation technologies, including zonal isolation packers. According to the study, one of the chief aspects fueling demand is rising need for effective zonal isolation technologies to prevent damage of casing and other formations in a wellbore. Moreover, zonal isolation packers are also widely used as an ideal anchor point for effective production tubing, creating untapped potential ...

Intervention equipment, planning can mitigate complexities that come with multiwell pad spacing

With high-density well spacing, additional considerations are needed around equipment placement and how one well affects other wells on the same pad By Joe Coleman and Cliff Meade, Wild Well Control An intervention operation on one well that goes poorly can affect adjacent wells and cause an even greater problem. Well spacing on multiwell pads becomes an issue that concerns equipment placement footprints. Hot Tap, Valve Drilling and Freeze services can be used for gaining well access and placing temporary mechanical barriers when circumstances do not allow for conventional intervention methods. Freeze Operations Freeze operations can be used in compact spaces and are beneficial for use on multiwell pads. Freeze services have been used for many years to place a ...

Well maintained

Automated, integrated equipment, more powerful diagnostics and wireline renaissance boost intervention efficiency By Katie Mazerov, Contributing Editor As sure as the sun rises and sets each day, all oil and gas wells will, at some point, need an intervention to maintain or boost production. From basic drill-out and cleanout operations using wireline, coiled tubing or a snubbing unit, to full-scale workovers to remove and reinstall the wellhead to replace downhole equipment, well intervention is a fact of life in the oilfield. It is also becoming more critical as operators drill deeper and longer in hotter and more pressurized environments. Equipment that is often automated and integrated, specialty services to meet the rigor of today’s well environments, new wireline applications, and ...
