EFFECTS OF DRILLING MUD CONTAMINATION ON THE PROPERTIES OF WAXY CRUDE OIL

Platform, a Journal of Engineering, 2018
Contamination of crude oil with drilling mud normally occurs during drilling process. The contamination may change the properties of crude oil leading to inaccurate assessment of the first extracted crude oil. Incorrect prediction of crude oil properties

Biodiversity Strategies in Action—Empirical Evidence From the Food Value Chain

Business Strategy and the Environment, EarlyView.
ABSTRACT There is an increasing need for better understanding of firm activities that contribute to biodiversity preservation. Panwar, Ober, and Pinkse offer a valuable typology of corporate biodiversity protection strategies based on temporal and spatial dimensions, namely, the preloss (proactive) strategies of conservation and compensation, and the ...

Enhancing Oil Recovery and CO₂ Sequestration Efficiency in Ultra-Deep Heterogeneous Waxy Reservoirs: A Comparative Experimental Study

Energies
Ultra-deep high-pour-point oil (waxy crude oil) reservoirs under high-temperature and high-pressure conditions are characterized by severe heterogeneity and poor displacement efficiency, with the crude oil exhibiting a pour point of approximately 47 °C ...

Differential Scanning Calorimetry contribution to a better understanding of the aging of gelled waxy crude oils

Oil & Gas Science and Technology, 2019
Below Wax Appearance Temperature (WAT), waxy crystals appear within the crude oil and make it viscous with yield stress and shear thinning properties. Particular attention has been paid during the past works on different parameters such as temperature ...

Greenwashing Across Industries: A Scoping Review of Explanatory Factors, Reporting Tactics, and Disclosure‐Action Decoupling

Business Strategy and the Environment, EarlyView.
ABSTRACT This scoping review provides an industry‐comparative synthesis of greenwashing and disclosure‐action decoupling in sustainability‐related reporting. Guided by PRISMA, it reviews 73 peer‐reviewed articles published between 2016 and 2025 and organizes them into three streams: variable‐based explanatory, report analysis, and disclosure‐action ...

Gasoline and crude oil prices: why the asymmetry? [PDF]

Many consumers complain that gasoline and crude oil prices have an asymmetric relationship in which gasoline prices raise more quickly when crude oil prices are rising than they fall when crude oil prices are falling.

Flow characteristics of waxy crude oils in laboratory experimental loops

Mathematical and Computer Modelling, 1997
On the basis of experimental data, we develop a physical model which tries to describe the low temperature behavior of waxy crudes in laboratory experimental loops. The correspondent mathematical problem is investigated by performing a quasisteady approximation which is shown to be physically consistent.

Decomposing Crude Price Differentials: Domestic Shipping Constraints or the Crude Oil Export Ban?

, 2017
Over the past five years the U.S. domestic crude benchmark, WTI, diverged considerably from its foreign counterpart, Brent. Some studies pointed to the crude oil export ban as the main culprit for this divergence, but pipeline capacity was also scarce ...
