... laboratory testing, an integrated engineering approach to fracture modeling, operational considerations, and post-fracturing production analysis. The workflow evolved during the technology implementation cycle in a specific oil field, particularly the modeling step, which used a new high precision...

... Abstract After long-time water injection, thief zones (TZ) tend to form and reduce the effectiveness of water flooding in mature oil fields. Several profile control techniques have been developed to resolve this problem. The effect of profile control depends on quantitative calculation of pore...

... The characteristics of the oil field can be summarized as fluvial facies, strong heterogeneity, heavy oil, loose formation, high chance of sand production, strong edge-bottom water energy, strong production capacity, wide use of horizontal wells, and high water cut. The fluid type...

... acquisition system. The fibre optic sensor configuration is shown in Figure 4 . Abstract The advent of Digital Oil Fields (DOF), Data Analytics and Artificial Intelligence has led to an increase in the number of instruments installed at wellheads and also an increase in the reliance...

... fractured horizontal wells to improve resources in this mature conventional oil field with ongoing pressure support and tertiary recovery operations. The modeling techniques used in this method can be extended to other mature oil fields to unlock bypassed oil setting a precedent to re-evaluate mature oil...

... examined in the study. The research was carried out for the log data from Williston Basin, USA and the Norwegian Lille-Frigg oil field on the North Sea. Sonic log (DT), neutron porosity log (NPHI), deep resistivity log (LLD) as well as density log (RHOB) were utilised in the study. A python program has...

.... On the other hand, CO 2 injection into commercial oil fields have several advantages and account for the majority of the current portfolio of CO 2 storage sites and likely to remain the dominate storage options for the initial phase storage projects. Oil fields are well characterized and have...

... for the NPF methods is 488.7 million USD, which is lower than that of new area productivity construction, 900-1100 million USD, that of low permeability oil fields, 1200-1400 million USD, and that of tight oil, higher than 1500 million USD. Using input to output ratio as economic evaluation method...

... unconventional heavy oil development makes more requests comparing to onshore heavy oil fields. Also, thermal stimulation is a process of depressure. Therefore, as the development time extended, reservoir pressure dropped and oil production decreased obviously. After several years of theoretical study...

...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...

.... This was addressed by developing the Reservoir Technical Limits (RTL™) process; the process and its application to oil fields was described in a 2009 SPE paper (109555). The present paper describes subsequent progress in developing RTL™, including a description of a new gas efficiency factor framework for use...

... Abstract Recently, Enhanced Oil Recovery (EOR) application in offshore oil fields is receiving significant attention. The size of targeted offshore oil fields is generally large, because their Original-Oil-In-Place (OOIP) should be sufficiently large to overcome the high cost of offshore oil...

... for geothermal exploitation of the co-produced water from wells in the Villafortuna–Trecate oil field in Italy, which has an aquifer that not only provides pressure support to the reservoir, but also represents an in-situ hydrothermal resource, without the need for external water recirculation. The study...

... and closed systems, and abandoned gas fields, as each have different storage limitations. Also, CCUS-type projects, which realistically only include abandoned oil fields, can be further subdivided to reflect the operational and commercial characteristics of different EOR schemes. It is hoped...

... Abstract Located in offshore South China, Panyu oil field has entered into mature development phase after a decade of intensive production. A new horizontal wells campaign has resumed since 2012 targeting the remaining thin oil column reserves that are being squeezed by strong bottom water...

... to identify the low-resistivity J 1   1 formation of Z oil field. First of all the common causes of the low resisitivity pay occurance were investigated using published literature sources. Then the wells where the productive J 1   1 formation was characterized by anomaly low...

... along 900 meters in a Colombian oil field. The selected well to apply this technology increases its daily oil production over 160%, well head pressure decreases 95%. Chemical dosification was optimized and BS&W values required by the control system were reached by heating technology. Additionally...

... Abstract The Peng Lai (PL) 19-3 Oil Field, located in the ConocoPhillips operated Bozhong 11/05 Block in the central southern Bohai Sea, offshore China, is currently the largest offshore oil field in China. The trap is a complex wrench anticline developed along the Tanchen-Lujiang fault system...

... are interdisciplinary full time team efforts by approx. 6-8 students over approx. 8 weeks. Since 2008 all projects are carried out on real data from real fields. The recent group projects are defined around the data for five oil fields abandoned in the 1990ies at 15 USD/bbl scenarios. The data include seismic, logs...
