The Effects of Dependence on Brazilian Third-Party Logistics Satisfaction

ABSTRACT Context: studies argue that similar levels of dependence are essential for supplier satisfaction in buyer-supplier relationships. However, asymmetric relationships can also lead to supplier satisfaction. Objective: this paper investigates the effects of benefit-based dependence (positive motivations for maintaining relationships) between buyer and supplier and supplier satisfaction. Methods: response surface analysis (RSA) was used to test the relationship between third-party logistics (3PL) dependence and satisfaction dimensions in 174 dyads. Results: the results demonstrated that about supplier satisfaction, instead of dependence asymmetry what really matters is the degree of dependence between the parties. The more dependent one part is on the other, usually, the greater the supplier’s satisfaction. In many circumstances, a degree of dependence is acceptable and necessary to access resources and opportunities. Conclusions: the interaction between buyer and supplier dependence and supplier satisfaction is complex. Situations of dependence asymmetry in which the supplier is highly dependent on the buyer may still be satisfactory.

Using Response Surface Analysis to Estimate Time of The Gas-Water Contact Lift in Yamburg Gas Field Conditions

Like many of the fields in northwest Siberia, the Yamburg oil and gas condensate field is in the final production stages. This, therefore, results in an accumulation of a large amount of formation water in the inflow at the bottom of the well. Response surface analysis is used as a new technique to gain a detailed understanding of the relationships between combinations of two predictor variables and an outcome variable. This approach was applied to the Yamburg field to estimate the time of the gas-water contact, considered as the result variable, by taking into account two groups of predictive variables which correspond to the reservoirs grouped by their lithological characteristics. The results of the predicted gas-water contact time were compared to the expected gas-water contact time, the data of which were taken into account for the study. Using the model parameters as well as the three-dimensional response surface, which was constructed to facilitate and improve the interpretation of the results, it was then possible to predict the gas-water contact time under certain conditions.
