treated sea water is the most significant source of water and surfactant floods. the various chemicals employed in treatment plants should be compatible with surfactant systems. based on surface tension experiments, the activity of these chemicals is examined over a wide range of concentrations in different solutions, including distillated water, sea water by using three types of surfactant mix...

The paper presents a new optimization model and solution approach for the investment and operations planning of offshore oil and gas field infrastructure. As compared to previous models where fiscal rules and uncertainty in the field parameters are considered separately, the proposed model is the first one in the literature that includes both of these complexities in an efficient manner. In par...

Abstract Affected by the surrounding injection and production wells, formation near infill adjustment well is in an abnormal pressure state, drilling completion operations are prone to complex situations accidents such as leakage overflow. The conventional shut-in method close all water wells around ensure safety of operation, but at same time reduce oil field production. This paper proposes a ...

With the development of oilfield exploitation in China, in-depth understanding change polymer flooding injection-production index can effectively alleviate contradiction and improve production efficiency. Based on this, taking Daqing as an example, this paper makes a detailed analysis classification stages prediction methods indicators for first second oil layers, mainly discusses variation rul...

The flexible drilling method of ultra-short radius sidetrack horizontal wells is an effective to utilize the remaining oil at top thick reservoirs. By analyzing current status SZ oilfield well network, development stage and sand body characteristics, combined with characteristics lateral technology, areas formations suitable for tapping are identified, criteria selecting established, which a gu...
