AGL: Open for Business

The AGL team is excited to be continuing its research, consulting, and publishing plans for 2020. Tim Dooley has received permission to continue operating his lab, but everyone else has made the switch to working from home thanks to the expert support supplied by the BEG IT team. Here are some of the highlights of our ongoing work:

 

Consulting

In-person visits are obviously off the table for a while, but, as a reminder, all AGL member companies are entitled to one free day of consulting each year from any of the AGL research staff. We are all also available for on-line visits and discussions upon request.

Murphy logo

Dr. Stanbrook with Murphy in Houston, visited the AGL offices in early March. He visited Frank Peel, Gillian Apps and PhD student Donald Christie (Southampton University) in his capacity as Donald's co-supervisor.  They discussed the forward modelling software Onlapse, which Donald is developing from Frank's early prototype. They discussed how Onlapse currently models the interplay between structural growth and sediment flux to a basin, and we touched on future applications of the software.
