Interpretable Machine Learning for Estimated Ultimate Recovery (EUR) Prediction for the Bakken Tight Oil Play, Williston Basin, USA

Journal of Petroleum Geology, EarlyView.
ABSTRACT Estimated Ultimate Recovery (EUR), often calculated from production decline curve analysis (DCA), is a key indicator of long‐term well performance in petroleum reservoirs, including unconventional plays such as the Bakken Formation in the Williston Basin in the northern United States, which is the objective of this study.

Combination of In Ovo Nutritional Components Improves Embryonic Development, Growth Performance, and Gut Health in Broiler Chickens

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT This study evaluated the effects of intra‐amniotic administration of combined energy, amino acid, and vitamin sources on embryonic development, post‐hatch growth performance, and intestinal health in broiler chickens. On Day 18 of incubation, 460 fertile Ross 308 eggs were allocated to four groups: non‐injected negative control (NC), saline ...

Trait‐based plant ecology: some history and some future

New Phytologist, EarlyView.
Schematic of plant species range boundaries, some mechanisms that might set them, and some traits that might explain them. Summary Since around the year 2000, trait‐based ecology has become self‐aware as a strand of research within ecology. How did this happen? What is trait‐based ecology now? And where might it go in future?

Mystery and misery of locally‐delivered drug therapy in periodontics. Historical concepts and current state

Periodontology 2000, EarlyView.
Abstract The primary objective is to critically analyze approaches to local therapy for periodontal disease, particularly in light of its well‐established systemic implications. We specifically address common misconceptions and overestimations regarding the potential of local treatments in contrast to their actual clinical effectiveness.

Alternative approaches to dryland reclamation enhance vegetation cover and soil stability at a former uranium mine

Restoration Ecology, EarlyView.
Abstract Introduction Conventional reclamation methods to recover dryland ecosystems after mineral extraction often have low success. Alternative reclamation techniques may help overcome the many challenges to establishing persistent native vegetation and stable soils.

Comparing the role of ‘security’ in EU energy and agri‐food law

Review of European, Comparative &International Environmental Law, EarlyView.
Abstract In EU energy and agri‐food law, ‘security’ is constantly invoked to justify legal action and to guide the adoption and interpretation of law. This article compares the concepts of energy security and food security, focusing on their relationship to sustainability, and asks whether invoking security enables or obstructs each sector's ...

Cement Slurry Contamination With Oil-Based Drilling Fluids

Journal of Petroleum Science and Engineering, 2017
Abstract Primary cementing constitutes the displacement of a cement slurry in an annular oil well. In the event of an unwanted mixture of drilling fluid and cement slurry during this operation, cement properties may be compromised. The aim of this study was to investigate the contamination in cement slurries caused by oil base drilling fluids ...

Diffusion Of Gas In Oil Based Drilling Fluids

SPE Production Operations Symposium, 1997
Abstract Background gas has been observed in oil based drilling fluids in contact with gas bearing formations. It has been postulated that such background gas is caused by diffusion. The objective of this study was to quantify the transport of gas by diffusion.

MANAGEMENT OF DRILL CUTTINGS WITH OIL-BASED DRILLING FLUIDS

News of the Tula state university. Sciences of Earth, 2019
Petroleum is one of the main sources of energy in the world. Oil production is associated with generation a huge amount of drilling waste, which impacts the environment negatively. Oil-based drilling fluids are widely used nowadays, but they are more dangerous than waster-based drilling fluids.
