A well has been drilled through a target zone but has not yielded significant hydrocarbon quantities (condensate, oil, or gas). On one side, it may imply zero percent hydrocarbons, i.e., none discovered at all. It could also mean that no commercially valuable hydrocarbons are available. A dry well analysis investigates if a well would succeed at producing commercial quantities of hydrocarbons.

The unavailability of Hydrocarbons can be caused by various factors, including the absence of seal, defective cap rock, and structural closure. It is possible to detect structural closure with a seismic method, but determining the exact structure of cap rock can only be achieved with a more effective method that evaluates the logs and density, among other things. It is critical to determine whether or not the caprock has been fractured or not, and check to see that the analysis is valid and that the horizons have been marked correctly.

Analyzing non-productive wells is complicated since every well has its unique characteristics and set of causes for not possessing hydrocarbons. The absence of a stratigraphic trap HC charge, reservoir, and an ineffective seal are the most common reasons for a dry well. It may be necessary to analyze the structure and seal competency, which is easily accomplished with TVT.

One of the most commonly used ways of analysis is the application of 2D or 3D seismic data analysis. Still, this method may not be as effective for checking the seal and structural soundness as other methods. Structure trap seals and closures may be three-dimensional, necessitating a more accurate analysis by Thermovision Tomography.

You want to get to the bottom of these major issues as quickly as possible. TVT collects this information and analyzes them promptly. A TVT analysis would concentrate on the primary risk aspects of reservoir, seal, trap, structure, and hydrocarbon charge. Testing the reservoir using TVT techniques will reveal the presence of hydrocarbons in it. If the reservoir contains hydrocarbons, the thermal signature will be different than if the reservoir is void of hydrocarbons. Using this information, one may create a map of the hydrocarbon-carrying horizon in the underlying strata. Organizations that conduct reservoir tests with seismic methods can apply and overlay TVT results to corroborate their information and deliver better results.

A geological model supports many well-drilling plans based on seismic, pressure production, and wireline logging data from neighboring wells. While these methods are good, adopting a TVT solution is more accurate and efficient. The result of the analysis will aid in the correction and fine-tuning of the geological model and prevent time wastage in the drilling of dry wells. OilDynamix can use the TVT solution to identify the root causes of subsurface challenges and make recommendations for resolving such.
