...) exceed 100 million cubic meters in the Guantao Formation, Bohai Basin. These LRP reservoirs are a crucial component in increasing both reserves and production in this oilfield. In general, LRP can be defined as reservoirs with a resistivity ratio of less than 2 between oil-bearing and adjacent water...

... Abstract The exploration and development of Bohai Oilfield is gradually moving to the deep stratum. However, it is difficult to drill in the deep stratum due to complex pressure system and multi-layer buried hill. This paper analyzes the lithologic characteristics of the deep buried hill strata...

... Abstract The CN oilfield is the main block of the X oilfield to increase reserves and production. However, the wells in this area are ultra-deep, and many sets of complex and difficult-to-drill formations are encountered in top-down drilling, which brings significant challenges to the drilling...

... of hot water and heat-resistant foam plugging, obvious effect of precipitation and oil increase was achieved in two horizontal wells of LD2 bottom heavy oilfield. After the measures, the daily oil rate increase from 10 m 3 to 40 ~ 70 m 3 , the water cut reduced from 74% ~ 92% to 1% ~ 10%. LD2...

... Abstract CFD oilfield is an offshore structural bottom water reservoir located in the Bohai Bay basin. The oilfield is developed by horizontal wells. After the high water cut of the oil wells, all oil producing wells are converted into reinjection wells to meet the needs of the production...

... generators will be removed after PFS modification. The first reason is it is necessary to reserve a certain number of generator sets for waste heat utilization to meet the platform heat demand when electrical heating modification is not economical enough. At the same time, some oilfields do not have...

... reservoirs remains a challenging topic. This study proposes the use of Production Profile Logging (PLT)Logging in exploration wells in JZ oilfield characterized by fractured granite reservoirs, where DST could not characterize the sub-layers’ PLTs with in the thick layer of the combined test. With the use...

... production rate rises rapidly and begins to decrease.There are 48 wells with a proportion of 31.8%. Capacitance Resistance Modeling (CRM) Abstract M oilfield is complex carbonate reservoirs in the Middle East, with strong heterogeneity, high permeability zones, local dissolution fracture area, high...

.... Abstract For water-flooding oilfields, both indoor experiments and mine field practices have confirmed that long-term water flooding can change physical properties, wettability, and fluid parameters. The comprehensive performance of these changes is that the relative permeability curve of oil and water...

... Abstract A oilfield, located in Iraq, is a large multi-layer oil field dominated by carbonate reservoirs of cretaceous Mishrif formation and Tertiary Asmari Formation. A oilfield is located in the transition zone between Zagros orogenic belt and the eastern edge of Arabian platform, mainly...

... recovery factor, and lack of experience of development adjustment in high water cut period, which result in oilfields in low level development stage for a long time. Taking Qinhuangdao 32-6 oilfield as the target area, the study of stratigraphic subdivision and well pattern adjustment in high water-cut...

... Abstract There is large amount of heavy oil resources whose oil viscosity over 350 mPa·s in Bohai Oilfield and their producing degree and production performance are relative low for lacking of effective exploitation technology. For seeking effective production technology for heavy oil...

... Abstract With most oilfields at Bohai Bay enters into middle and late waterflood development stage, the oilfields have high water cut but low recovery degree. Chemical methods of enhanced oil recovery (CEOR) such as polymer are applied. However, the degradation and retention of polymer inside...

... The development challenges of this oilfield mainly include: 1. The scale of reserves is small. the threshold of offshore oilfield development cannot be less than 2000×10 4 m 3 , while the proved reserves of B oilfield are only 1600×10 4 m 3 . 2. The quality of reserves is poor, characters as thin...
