Abstract In developing heavy oil from thin bottom water reservoirs, horizontal wells are mostly used in Bohai Bay, China. To maximize production and avoid early coning/cresting, usually placed near the top of pay sands initially produced with small pressure drawdown. However, responses different display significant variations even though they operated under similar conditions. Some show premature coning rapid cut rising although high quality targeted, while others much delayed breakthrough...
Summary BZ25-1s field in Bohai Bay, China, is characterized as a complex channelized fluvial reservoir which small meandering channels were deposited at different geological times stacking and cross cutting each other. There are many isolated systems following channel distributions. Early production showed steep pressure decline. Quick implementation of water injection was needed to arrest the fast decline stabilize pressure. While designing water-injection plan, we faced number challenges,...
Abstract This paper presents the findings from study and application of profile modification in offshore fields discusses how to select proper agents manage operation for reservoirs with different geological characteristics. China inner sea-Bohai is one most important oil-producing areas China. The are complex a great variety geology properties rock oil. Most them medium high permeability heavy oil reservoirs. Because viscosity ratio water strong heterogeneity formations, injected break...
Abstract JZ25-1S oil field located in Bohai bay which has a thin rim with gas cap on top and aquifer below, this to supply fuel gases the residents. To achieve maximum recovery, force balance between drive, expansion, viscous withdrawal shall be carefully studied for type of reservoir at various stages production lifecycle. Available methodologies including analytical, simulation are used optimize development strategies, well type, location, drawdown so on. Using horizontal wells develop...
New oil discoveries in the southwest area of Bohai Bay by CNOOC Limited-Tianjin and other international companies are mostly found Middle Miocene Minghuazhen Formation. The reservoirs dominated fluvial channels shallow lacustrine deltaic systems. On seismic, often difficult to follow, a terrestrial succession such as Formation typically lacks continuous reflections trace on seismic data. These depositional facies, along with complex postdepositional faulting, makes interpretation reservoir...
Abstract QHD32-6 is typical offshore heavy oil filed with about 1.1 BSTB of OOIP and a very complex fluvial reservoir in Bohai Bay, China. The field was developed by CNOOC, Texaco Arco 1998. Based on the Original Field Overall Development Plan, forecasted waterflooding recovery 17.4% due to sand OOWC, high crude viscosity active bottom edge water. After starting production, water almost broke through immediately many producers production disastrously declined. two years operation practice,...
The geological reservoir conditions of fluvial oilfields offshore in Bohai are complex, with thin layer reservoirs, significant horizontal changes, poor connectivity, so these face the challenges production well deployment, fine description, optimum resource allocation, and on. To realize efficient development oilfields, this research has formed technique description quantitative characterization a sparse network, regional sedimentation single river recognition, network optimization sand...
Abstract In this paper we detail the work done in rearch for horizontal well reasonable drawdown pressure of heavy oil reservoir with bottom water based on detailed analysis geological, reservoir, production history, data and conditions intent to enhance rate recovery efficiency a water. We study history relate optimizing water, like thickness, standoff over contact, honrizontal section length, barriers distribution viscosity in-place oil. This breaks up past development idea controlling...
The Liaodong Bay sub-basin is a classic non-marine rift in the Bohai Bay, northeastern China. study area located on east side of Liaoxi uplift west slope sub-basin. It sits draped anticline zone above paleo-uplift and contains second biggest offshore hydrocarbon field found China to date. bound by TanLu fault zone, most active largest eastern China, has been from Mesozoic present. spatial distribution temporal evolution depositional systems lacustrine basin were significantly controlled...
Abstract Qin Huang Dao 32–6 (QHD32–6) oil field located at Bohai Bay of China is a large heavy (74–260mPa.s) with flat structure, multi-pay zone, complex and water contact system discovered by CNOOC (Fig. 1). The development plan drilling vertical wells to penetrate multi zones well space (350-400m) in 3 blocks (North, South, West). Due comingle production pattern quickly coning the bottom water, became mainly producer faced be shut-down after short period first oil. Measurement like zone...
Abstract BZ25-1s field in Bohai Bay, China is characterized as a complex fluvial channelized reservoir where small meandering channels (100-300m wide and 500 - >1000m long) were deposited at different geological times cross-cutting each other. There are many isolated systems following channel distributions. Early production showed steep pressure decline. Quick implementation of water injection needed to arrest the fast decline stabilize pressure. While designing plan, we faced number...

Abstract Fault reactivation induced by excessive reservoir water pressure in oil fields is suspected as one of the possible perpetrators that caused crude eruption to surface. This can lead significant financial losses related environment cleanup and curtailed production. During fluid production injection, changes stress have a influence on behavior. sealing ability key factors control hydrocarbon preservation. If these faults are reactivated, their permeabilities will likely increase,...
