Hydraulic well fracturing has been an important practice for well stimulation along the history of the hydrocarbon industry. Therefore, accurate and practical assessment of the fracturing job should be of importance. Interpretation of well pressure and rate test data in vertical finite-conductivity fractured hydrocarbon wells by the TDS methodology and conventional analysis are presented in this paper. The accuracy and practicality of the developed equations are successfully tested with synthetical examples and a field case.

“…As commented by Escobar et al (2018), there exists four ways of well pressure and rate data interpretation: (1) Type curve-matching, (2) Conventional straight-line, (3) Nonlinear regression analysis (computer assisted) and (4) TDS Technique. The last one can be found with detail in the books by Escobar (2015Escobar ( , 2019. This method uses characteristic points and lines found on the pressure derivative or reciprocal rate derivative versus time log-log plot from which analytical and direct-forward expressions are employed to find reservoir parameters.…”

et al. 2021

This paper presents a well test interpretation methodology using characteristic points and lines found on the pressure and pressure derivative versus time log–log plot for the characterization of a finite-conductivity fractured vertical hydrocarbon well in a double-porosity (heterogeneous) formation considering a new and practical analytical Laplacian model which require less computational time and have more accuracy than semi-analytical models. Some existing equations are found to work well for the new model, and new expressions are developed. The accuracy of the developed equations is successfully tested with synthetical examples.

Interpretation of pressure interference tests for wells connected by a large hydraulic fracture

Shale formations are being exploited in several places around the world. Thus, an adequate characterization of such formations is recommended. In this work, two interpretation methodologies—TDS technique and conventional analysis—are implemented for determining the fracture permeability, from interference tests, between two wells connected by a large hydraulic fracture. Therefore, equations have been developed for both interpretation techniques and tested with synthetic examples. The estimated fracture permeabilities closely match the values initially used for the simulation of the tests.
