A large increase in drilling and production costs in the USA Shale Oil sector will likely slow the growth of production from the Permian Basins. To just maintain production hundreds of new wells must be drilled each year due largely to the rapid decline in tight wells. In the Permian »
Siem Reap has 98km of new roads and new sidewalks much of which has been paved with interesting felsic intrusive rocks from quarries in Shandong Province in China. The composition ranges from granodiorite to tonalite and is locally granophyric and pegmatitic. The intrusive consists dominantly of plagioclase, quartz, pyroxene and »
I recently had a chat with the Artificial Intelligence application, ChatGPT. ChatGPT (Generative Pre-trained Transformer) is a chatbot launched by OpenAI in November 2022. It is built on top of OpenAI’s GPT-3 family of large language models, and is fine-tuned (an approach to transfer learning) with both supervised and reinforcement learning techniques. »
