On the Martin Linge field in the Norwegian North Sea, Total had been experiencing multiple challenges, including severe losses, unstable formations and excessive downhole shock and vibrations. To address these challenges, the operator turned to National Oilwell Varco (NOV) and its IntelliServ wired drill pipe, Saskia Schils, Head of Engineering - Exploration Drilling at Total E&P Angola, explained. In this video from 1 March, Ms Schils explains the results that were achieved. Reina Teelken, Senior Technical Advisor at NOV, also shares the company’s plans for taking the technology forward. More information about this project can also be found in IADC/SPE 178863, “The Use of Wired Drillpipe Technology in a Complex Drilling Environment Increased Drilling Efficiency and Reduced Well Times.”

Weatherford has developed the SwageHammer integrated liner hanger system to reduce leak potential and improve reliability in high-angle, high-pressure and high-temperature wells in deepwater. The company introduced the liner hanger system at the 2016 IADC/SPE Drilling Conference in Fort Worth, Texas. In this video from the conference on 3 March, Sean Yakeley, Product Champion-Well Construction Products for Weatherford, explains how the SwageHammer combines the features of conventional and expandable liner-hangers to reduce uncertainty during liner installation.

Next-gen microchip plots cracks, pores through frac fluids

The size of this newly developed microchip, including the on-chip camera and the pads, is only 0.55 mm by 0.85 mm.

Rice University’s Integrated Systems and Circuits (RISC) laboratory has developed a new generation of microchips, approximately the size of a grain of sand, that travels downhole through fracturing fluids to plot the cracks and pores through which oil and gas move to the surface. Activated by electromagnetic signals sent from an aboveground transceiver, the microchips return real-time data to create high-resolution maps of reservoirs and formations formed by hydraulic fracturing.

Dissolvable tools, plug-less and wave fracturing among innovations delivering more efficient multistage completions

The Infinity dissolvable plug-and-perf system uses degradable fracturing balls and seats instead of plugs to isolate zones during stimulation. The ball and seat disintegrate into a fine powder, eliminating the need for milling and enabling full-bore production. The system is suitable for multistage stimulation in various well geometries, including extended-reach wells and underpressured reservoirs.

The past 12 months have been marked by market volatility, pressures to cut costs and a drastic reduction in the number of onshore wells drilled. In the unconventional sector, however, innovation for multistage completion technology has not diminished. R&D efforts are pressing on in response to operator demands to drive down costs and boost recovery.
