... Abstract At present, the Bohai Oilfield has entered the late stage of high water cut, with a high degree of flooding and an average water cut of more than 80%. Horizontal wells were widely used in tapping the potentials of high water-cut oilfields with avoiding local water flooding, accurately...

...Production characteristics of the horizontal wells in Q oilfield Figure 2 is the main downhole structure of the new developed water control technology. It is mainly composed of ICD/AICD screen and continuous-barrier built by the fine particles in the annulus between the wellbore...

... in a few hours [ 15 - 19 ]. As a result, in almost 50% cases at Yugomashevskoe and Abdylovskoe oilfields, a water break-through leads to higher water cut than it was before stimulation job. In the ESN technology for reservoir stimulation, the ESN combines two vital functions for stimulation of wells...

... screens or gravel packing. The effect of gravel packing is better than using only high-quality sand screens. The oil field is a river facies with strong heterogeneity ( figure 1 ). H oilfield has a complex oil-water system and multiple reservoir types which include edge water and bottom aquifer...

... time drilling parameters within a sliding 4-hour window. For each measurement, the model calculates the probability of an accident and warns about anomaly of particular type, if the probability exceeds the selected threshold. Our training sample comes from 20+ oilfields and consists of sections...

... Abstract An optical fiber has been utilized to continuously acquire liquid production profiles in horizontal well in X oilfield. The results obtained from the dynamical monitoring system confirm the time-varying law of the physical property under the condition of high-water flooding, which can...

... In this paper, based on the study of sedimentary microfacies in J oilfield, northern Albert Basin, Uganda, Rocktypes were divided by core analysis, log interpretation, thin section identification, analysis and laboratory data, and then established microfacies model, Rocktype model and physical...

... on the productive capacity of different pay intervals. However, due to the high operational cost, these measurements are typically quite scarce, particularly in offshore oilfields. In complicated reservoirs where hydrocarbon viscosity shows vertical variation, the net pay cutoffs change as well and hence even more...

... sequentially and place it in the simulation space constrained by predefined rule and conditioning property. We applied this method to construct the stacked point bar model of M oilfield. Multiple equal probable architecture models were built and were compared with each other through history matching...

... Abstract CFD11-X is an offshore oilfield in Bohai Bay Basin. Since the drilling data is less and the resolution of seismic data is not high in the deep, our knowledge to the fault system and sand bodies is not sufficient. During the implementation of overall development plan (ODP), it gradually...

...Fine characterization of reservoir configuration at high water-cut stage Abstract Qin Huang Dao 32-6 (QHD32-6) oil field located at Bohai Bay of China is a large fluvial heavy oil field discovered by CNOOC. This oilfield has come into high water-cut (88.6%) &low annual recovery rate...

... Abstract The architecture of sandy braided rivers, especially the mid-channel bars and the internal intercalations, plays a key role in the enhancement of remaining oil. Based on ancient outcrops, modern deposits and geological models, taken P oilfield as an example, this paper studies...
