Computer Simulation and Analysis
At SCL, we offer not only qualification testing but also expertise in computer numerical modeling and analysis of downhole completion systems. By constructing numerical models, we can analyze the performance of downhole equipment under fluid flow conditions. This service can be characterized as an analytical study of physical and chemical processes in the near-wellbore space. Such studies provide additional insights into the potential use of downhole equipment and complement qualification testing studies. In some cases, analytical studies are necessary to properly set up the physical testing of equipment. For instance, to test the wire screen’s erosion resistance and durability, we need to create an erosion model of the screen surface, calculate it, and set the erosion test parameters accordingly. Thus, computer modeling is an essential component of equipment qualification testing.
Our Laboratory Offers Numerical Computer Simulation Services in the Following Areas:
- Numerical calculation of the fluid inflow;profile along the well;
Fluid inflow model is built according to formation permeability data near the well. The model allows predicting the inflow profile, identifying areas of unproductive sections of the well, and determining the characteristics of fittings when using the ICD. The simulation result can be represented in the form of fluid flow profile diagrams along the well.
- CFD fluid flow simulation in downhole equipment units;
This service includes fluid flow computer simulation through downhole equipment. This modeling allows to analyze equipment performance in different reservoir conditions and fluid flow regimes.
Numerical equipment erosion model;
It is necessary to simulate this process to assess the impact of erosion over the long term. The model is verified based on physical tests of erosion impact. The computational model can be effectively used to select the wire profile of the slot screen.- Determining the position of a liner as it reaches the bottomhole during its descent into the wellbore;
This calculation evaluates the likelihood of a liner reaching the bottomhole point based on data about the well trajectory.
- Risk analysis of an unproductive fluid breakthrough into the well (water and gas);
The well flow zone model is a useful tool for analyzing potential water and gas breakthrough threats to a well. To accomplish this, the model must be supplied with information about the boundaries of the gas cap and the surface of the water-oil contact. Utilizing this model can effectively reduce the risk of unproductive fluid breakthrough. - Calculation of the mechanical strength of the screen structure under axial, bending, and torsional forces;
The finite element method is employed to evaluate the strength of the screen structure, assessing the impact of critical loads on the integrity of the screen configuration and its slot clearances. This analysis identifies the most vulnerable components of the structure with respect to various force loads.
