Biogeography and Diversity of Multi-Trophic Root Zone Microbiomes in Michigan Apple Orchards: Analysis of Rootstock, Scion, and Local Growing Region

Autor: A. F. Bintarti, J. K. Wilson, M. A. Quintanilla-Tornel, A. Shade

Publikováno v: Phytobiomes Journal, Vol 4, Iss 2, Pp 122-132 (2020)

Soil is a highly heterogeneous environment with many physical and chemical factors that are expected to vary within and across fruit orchards, and many of these factors also drive changes in the soil microbiome. To understand how biogeography influen

Warming autumns, fewer butterfliesMany recent studies have revealed sweeping declines in insects over the past few decades. Butterflies are no exception. Foristeret al.used three different datasets, collected by both experts and community scientists,

HFTO Solved: Proven Mitigation of High Frequency Torsional Oscillations in Motor-Assisted Rotary Steerable Applications

Autor: J. K. Wilson, G. Heisig, C. Freyer

Publikováno v: Day 1 Tue, March 08, 2022.

High frequency torsional oscillation (HFTO) has gained considerable attention over the past several years due, in large part, to the continued use of motor-assisted Rotary-Steerable Systems. The consequences of such vibration events can be increased

Evidence from galactic cosmic rays that the sun has likely entered a secular minimum in solar activity

Autor: F. Rahmanifard, A. P. Jordan, W. C. Wet, N. A. Schwadron, J. K. Wilson, M. J. Owens, H. E. Spence, P. Riley

Since the beginning of the space age, the Sun has been in a multi-cycle period of elevated activity (secular maximum). This secular maximum is the longest in the last 9300 years. Since the end of solar cycle 21 (SC21), however, the Sun has shown a de

High-Frequency At-Bit Measurements Provide New Insights Into Torsional Dynamics When Drilling With Steerable Mud Motors in Unconventional Horizontal Wells

Autor: Tim Whitacre, Gerald Heisig, J. K. Wilson

Publikováno v: SPE Drilling & Completion. 34:414-425

Summary New insights into torsional bottomhole-assembly (BHA) dynamics have been gained from high–frequency at–bit measurements when drilling with steerable mud motors in horizontal wells. Steerable mud motors are traditionally thought to decoupl

Field Validation of a New Bottomhole-Assembly Model for Unconventional Shale Plays

Autor: J. K. Wilson

Publikováno v: SPE Drilling & Completion. 34:189-206

Summary A new drillstring model has been developed that determines the static and dynamic behavior of bottomhole assemblies (BHAs) in 3D wellbores. An attempt at validating this model with field data is presented, and it shows a close agreement betwe
