Prediction of coalbed methane reservoir performance with type curves
This study presents a set of production type curves for CBM reservoirs that would help the producers to predict the production from their CBM wells. As a consequence, the producers would be able to make better, more informed decisions regarding the CBM resources in the region. A reservoir model …

Development of gas production type curves for coalbed methane reservoirs
… were performed. A unique set of gas production type curves for coalbed methane was developed as a simple and economical tool for small producer to evaluate economic feasibility, increase recovery, and maximize efficiency. A correlation for peak gas rate estimation was also proposed as an …

Automatic type curve matching for predicting gas wells production
The determination of gas wells production using type curve matching is one of the methods used in evaluating gas reservoirs. Matching curves manually is time consuming and exposed to human error. Aminian type curves unlike the other type curves accounts the pressure dependency of gas properties and …

Single- and cross-hole pneumatic injection tests in unsaturated fractured tuffs at the Apache Leap Research Site near Superior, Arizona
… (1998) employ pressure and pressure-derivative type-curves to analyze transient data. Air permeabilities determined from transient analyses agree well with those derived from steady-state analyses. Cross-hole pneumatic tests were analyzed by means of a graphical matching procedure using …

Analysis of Slug Tests to Determine Hydraulic Conductivity of Vertical Cutoff Walls
… One of the new methods involves a series of type curves that takes into account the compressibility of the backfill, overall effect of narrow wall boundaries, and eccentricity of the well intake section. The second new method is a modified curve fitting method, which employs a linear curve …

Evaluation of a Fractional Theis Equation
… The new fractional Theis equation solution type curves (drawdown and radius of influence) are evaluated for relationships between aquifer properties and a fractional Theis solution. The fractional Theis solution is then used to reanalyze the aquifer test data used by Cloot and Botha (2006) …

Problems of fluid flow in a deformable reservoir
This research is focused on development and enhancement of the model of fluid flow in a formation with stress-dependent permeability. Several typical axi-symmetrical problems of fluid flow in a multi-layered reservoir with account for wellbore storage and skin have been solved numerically. The …

Chemomechanical modeling of hydrogen-induced degradation at high temperatures
… HTHA is primarily based on the use of the Nelson curves published by the American Petroleum Institute (API) which are empirical and do not account for the underlying failure mechanisms, the material microstructure, and the operating conditions, e.g., applied stress level and time. The API …
