Well Performance Analysis and Monitoring

The flow behaviour inside and adjacent to the wellbore has an important impact on the overall performance of the Well. We employ some of the latest technological advances and tools to model the multiphase flow inside and near the wellbore while taking into account the factors which affect such behaviour.

iOG enables the performance of nodal analysis to model Reservoir inflow and Well outflow performance. Such Well models can be useful for determining optimized well parameters. Well modeling can be applied to designing, optimizing and troubleshooting individual wells.

The use of Well modeling approaches can be categorised as below:

  • Well configuration design for maximum performance over the life of the well
  • Completion design to maximize well performance
  • Detailed reservoir inflow performance modeling
  • Modeling Multiple completion and perforations
  • Artificial lift design
  • Equation of State models for condensate and volatile oil
  • Black oil models for oil and gas
  • Detailed fluid PVT modeling
  • Prediction of flowing temperatures and pressures in wells and flow-lines and at surface equipment for optimum design calculations
  • Reservoir, well and flow-line monitoring

Similarly Nodal analysis for the wells can be used for:

  • Selecting tubing and flow line sizes
  • Optimizing the system to produce the objective flow rate
  • Recognizing ways to increase production rate
  • Determining flow rate at which an existing well will produce
  • Analysing an existing system for abnormal flow restrictions
  • Predicting the effects of depletion on production capacities
  • Selecting the most economical time for the installation of the artificial lift and assisting in the selection of optimum lift method (Artificial lift design)

Using well models, the user can visualize the response of varying amounts of injection gas and injection pressure into the wells and field. Once Well models have been built and matched to measured data, they can be combined into field models. These integrated models allow the engineer to review many different scenarios to ensure that optimum field production is achieved.

iOG is uniquely positioned to provide a comprehensive range of services to maximize well availability and productivity, whilst minimizing regulatory and HSE issues. Rather than simply providing reactive services on request, iOG provides operators with a full range of well integrity services including:

The process is structured as follows:

GAP Analysis

iOG’s well integrity management capability provides operators with a cost-effective solution to the challenges of managing an ageing field.

Well logs provide insight into the formations and conditions in the subsurface, aimed primarily at detection and evaluation of possibly productive horizons. In addition to these logs that are used to characterize the wellbore, formation, and fluids, a number of logging tools are available to provide information during production operations.

iOG Solutions provides well log analysis and interpretation services for all kinds of logs and the well log correlation studies to find out accurate depth at which Oil & Gas is present. Our experts can provide interpretation and analysis services for all kinds of Open Hole Logs, Cased Hole Logs (also known as Production Logs) and LWD Logs.

Our analysis, study and calculation of log curve responses provides key parameters such as Porosity, Lithology, Permeability, Water Saturation, Resistivity, Mineralogy, Fluid type, Estimation of Hydrocarbon Saturation, Depth and Thickness of net pay, Estimation of volume of Clay fraction, Estimation of reserves of Hydrocarbon, Detection of Fracture, Formation Tops and Identification of Depositional Environment. Our team supports provide support to our clients for both qualitative and quantitative assessment of the reservoir using well logs.

Well Log Correlation

In the exploration / development stage, Log while drilling (LWD) processes are performed for a few wells. Well Log Correlation is then used to coorelate the data and uses it for interpreting and predicting properties of other wells using Measure While Drilling (MWD) info.

A snapshot of some of our interpretation services:

  • Correlating stratigraphy (rock layers) from one well to another, when interpreting logs from multiple wells
  • Interpretation of logs to gain an insight into regional and field-scale stratigraphy
  • Utilizing log response patterns and performing datum (flatten) on the logs from different wells on a time marker to remove the effects of depositional tilting

Production Log Interpretation:

Production Logging is one of a number of cased hole services that includes cement monitoring, corrosion monitoring, monitoring of formation fluid contacts (and saturations), perforating and plug and packer setting. Cased hole logs such as Calliper Logs (also done in Open Hole) provide information on the well bore diameter, Cement Bond Log tells about cement condition of the well and Casing Collar Locator tells about the placement of casing collar in the well.

Production logs are used to allocate production on a zone by zone basis and also to diagnose production problems such as leaks or cross flow.
