... demonstrated and discussed. While saturation garners more attention, well integrity is another main usage of pulsed neutron logging tool, which unfortunately is less explored when compared to saturation. In ACG, Pulsed neutron logging tool is also widely used for Gravel Pack Evaluation (GPE), water flow...

... energy has emerged as a significant focus in recent years. Geothermal well testing, akin to well testing in the oil and gas industry, is crucial for evaluating the economic viability of geothermal projects. Despite the similarities, there are fundamental differences in the hardware used for geothermal...

... to better evaluate low-resistivity pay zones in highly laminated shaly sand sequences. Although the results from this method are volumetrically almost correct, they are quite insufficient to deal with the distinctions between finely laminated sand, silt and shale. In order to calculate volumetric...

... Abstract The South Caspian Basin is known for its significant hydrocarbon reserves, particularly in sandstone reservoirs. Accurate reservoir characterization and evaluation are crucial for this region's successful exploration and production activities. Choosing the appropriate well logging...

... Abstract The Tengiz reservoir is known for its substantial bitumen content, requiring careful differentiation during formation evaluation processes. To accurately estimate the effective porosity, wireline nuclear magnetic resonance (NMR) tools were used in conjunction with other logging tools...

.... The conventional approach of a single-regime production logging may be ineffective due to the complex geometry of fluid flow in the near-wellbore zone around the well. The paper describes the experience of the multi-rate through barrier diagnostics as a method of improving hydraulic fracturing evaluation...

... Abstract Reserve/Resource estimation plays a crucial role in a feasible oil and gas business. Tendency of producing more from unconventional reservoirs and their relatively new as well as different structure brought on a learning curve for the applications of new reservoir evaluation methods...

... of fracture geometry is very important for optimal reservoir management and development. This paper describes the application of an advanced logging system to evaluate near-wellbore vertical fracture properties. Conventional production logging focusing primarily on wellbore flow geometry such as perforation...

... ppg) cement slurries. Two separate logging runs were performed to assess performance of standard and new generation transducer in 17.9ppg mud. Comparison of the results in 9.875-inch casing are presented in Figure 7 . Abstract Cement evaluation with wireline tools across two different casing...

... to evaluate the contribution of each interval to well operation. In case of water or oil flow along the surface of the proppant, only markers corresponding to their phase are released. Upon completion of all the works in the well, the well is put in the planned operation mode, then formation fluid samples...

The last is integration research of hard-to-recover reserve development and rolling exploration through conducting oil reservoir optimum selection. This research further...

..., where the level of instrumentation is low, production models might not be available, and the local expertise might be limited. In such situation, the principles of digital oilfield need to be adapted. This paper presents a staged implementation methodology, where the benefits and costs can be evaluated...

... Pressure Abstract Proper design, installation and evaluation of sand control completions is vital for ensuring sand control integrity and mitigating against production deferrals due to sanding events. This is becoming increasingly important in the ACG Field, located offshore Azerbaijan, where...

... and deployed to address specific well and reservoir challenges. The topics will include: – Evaluate the quality of the initial fill and subsequent changes to various types of proppant with stand-alone and time lapse logging for Open Hole Gravel Pack completions – Identification of scale depositing...

.... In addition, the field life will be extended from 2009 to 2025, and this will contribute to lifetime extension of the attached satellite fields. The main purpose of this paper is to provide a description of the multidisciplinary approach used for evaluation and planning of the Statfjord Late Life (SFLL...
