Drilling & Completion Tech Digest

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.

Technology champions build up business case for MPD adoption while advancing automation, training

Although managed pressure drilling (MPD) continues to gain traction across the industry, it remains incumbent upon service providers and technology champions to build and prove a business case for MPD. This remains challenging due to the nature of the technology. One of its key benefits is minimizing or eliminating kicks and losses. However, proving that something didn’t happen can be difficult. “How do you quantify non-events? How do you quantify something that didn’t happen?” asked Per Christian Stenshorne, EC-Drill Product Line Manager for Enhanced Drilling.

Cloud-computing, sophisticated models enhance meaning of downhole drilling data

Collaborative use of real-time telemetry to more effectively utilize the massive amount of data that is now available at the wellsite has been instrumental in taking drilling optimization to a new level in the past five years, according to David Johnson, VP, Research and Innovation for Petrolink. The company provides real-time data infrastructures that help operators and service companies manage and correctly use relevant information to analyze various drilling parameters, such as well hydraulics, torque and drag, vibration, bit selection and drilling fluids and rheology.

VisiTrak services may eliminate need for pilot wells in wellbore placement

As operators continue to target increasingly complex geological formations in deepwater reservoirs, accurate and efficient horizontal wellbore placement has become essential to productivity. Conventional methods for mapping out wellbore placement involve drilling pilot wells, which can cost millions of dollars to drill. Baker Hughes aims to remove the need for such pilot wells, while also improving recovery, with the VisiTrak Geospatial Navigation and Analysis Service, commercially launched in July 2015. “This represents the combination of two decades developing reservoir navigation,” said Jon Skillings, Product Line Manager, Reservoir Navigation Services, Baker Hughes.

Perspectives: Erin Welsh, Seadrill: Offshore work is not a career stepping stone but provides valuable opportunities for hands-on work, making real changes

For Erin Welsh, Technical Superintendent-Well Control Equipment at Seadrill, what started as a stepping stone became the foundation for a career. She attended the Colorado School of Mines starting in 1992 and majored in engineering, with a specialty in mechanical engineering. Her intention was to design equipment.

Data acquisition capabilities, durability enhanced in new crop of coiled-tubing, intervention tools

The need to keep pace with the increasingly long laterals that operators are drilling remains a driver for R&D efforts around well intervention and coiled tubing (CT). However, in the current price environment, that innovation must be coupled with the ability to lower costs. New CT and intervention technologies appear to be achieving such cost reductions by increasing equipment durability, which results in fewer trips out for replacement. In addition, more real-time data collection is being used to make real-time adjustments to maximize efficiency.
