... flooding technologies, polymer flooding has entered into industrialized applications stage in sandstone reservoirs. Polymer flooding has been applied in Daqing oilfield and 13% incremental oil recovery on average has been obtained over the past few decades. Polymer flooding has been also successfully...

.... And then, the influence factors of the miscible volumetric coefficient and the compositional sweep efficiency in CO2 flooding for low permeability reservoirs were obtained through reservoir simulation. Furthermore, the concepts mentioned above were applied in oilfields of SINOPEC, which can reasonably illustrate...

... rising increasingly. Therefore, it is an inevitable trend to develop improved oil recovery (IOR) technology for the matured oilfields. In this paper, the essential procedures and results of the second potential assessment for IOR in China are presented, and the IOR pilots in recent years are summarized...

... has been used to lower the viscosity and freezing point of heavy oil for the goal to improve physical and chemical characters of heavy oils. Several experiments of microbial enhancing oil recovery (MEOR) have been carried out in Qinghai Oilfield and Xinjiang Oilfield, China. 1 Samples and experimental...

This paper briefly introduces physical properties of waxy crudes in the major oilfields of China. With exploitation of Daqing, Shengli...

... Abstract. The Bohai Bay Basin which has been exploited for nearly 40 years is a composite basin consisting of the early Proterozoic-Paleozoic and Meso-Cenozoic formations. Since the discovery of the first oilfield the exploration course can be divided into 4 stages. In each stage there was its...

... Abstract. Technical and economic results of the horizontal drilling operations in the Palmar Largo PL-21 well confirm that horizontal wells are a valid, valuable production technique that can improve oil production economics. Located in the Palmar Largo oilfield, Northwest Sedimentary Basin...

INTRODUCTION The prospects of discovering new oilfields throughout the world are more and more associated with the difficult-access areas (deep shelf, permafrost zones, etc.) where oil production costs are many times higher than in the areas with favourable conditions...

... Abstract Over a period of 15 years an industrial experiment was carried out in the Devonian pool of the Bavly oilfield to determine the effect of well spacing pattern on the oil losses in the reservoir. The pool was drilled with 20 hectares distance between the wells. In 1958 each second well...
