PRIME is a set of Production Performance Indicators in PolyPrime software based on primary production history data (such as flow rates, formation and bottom-hole pressure, pressure tests, production logs) with zoom on wells and field areas which are dragging behind the expected recovery or pressure support targets due to integrity issues, poor connectivity or inaccurate understanding of the reservoir around these wells. This is a primary tool to select the candidates for additional data acquisition.
Multiwell Retrospective Testing is a PolyGon software aided workflow based on correlation between bottomhole pressure and flowrates history using multi-well pressure deconvolution technique and aiming to understand the potential drainage volumes, boundary type and its proximity, reservoir transmissibility, cross-well connectivity and reconstruct the history of formation pressure and productivity index. It gives a lot of constraints for future reservoir modeling. It also helps to identify wells with suboptimal performance and propose an adequate surveillance.
Multi-Scenario Field Development Planning is a specific workflow based on multiple iterations performed by professional asset teams or corporate individuals by means of PolyPlan web-facility which automatically translates the field activities (drilling, workover, conversions, surveillance) into the model runs and reverting back with production/surveillance results in conventional reporting formats. This exposes a newly built models to a wider range of corporate specialists and improves the chances of finding the best field development solution.
Reservoir Geology and Flow Modelling is a conventional 2D/3D full-field modelling workflow. In case the results of XPM exercises are available the RGFM takes the latter as input and the rest of the process simplifies to adjusting the facies distribution and their permeability/displacement properties to achieve well-by-well match to oil/gas/water cut history and available OH/CH saturation profiles.
Pulse Code Testing is specific implementation of pressure interference testing based on PolyGon software and bottomhole pressure/rate readings which can be executed in working wells without punishing production delays caused by responding wells shut-down. It provides estimation of reservoir permeability and thickness separately and in case of contrast fluids mobilities it shows a fair sensitivity to displacement efficiency. Although PCT can be performed over the existing PDG and surface flowrate data but the scanning accuracy can be substantially improved when using the zFlux downhole pressure/rate measuring facility.
Vertical Flow Profile is a combination of multi-rate production logging and bottom-hole pressure deconvolution in Polygon software which translates the flowrates and pressure readings into vertical pressure and productivity index profile in multilayer formation.
Cross-Well Pressure Modelling in Polygon software is important element of full-field Reservoir Simulations with a focus on few large-scale model properties (drainage volumes, boundaries, barriers, lateral permeabilities and effective thickness) which have a stronger impact on bottom-hole pressure response comparing to reservoir saturation and vertical permeability profile.
