AI-Based Decline-Curve Analysis Manages Reservoir Performance
Decline-curve analysis is one of the more widely used forms of data analysis that evaluates well behavior and forecasts production and reserves. This paper presents technologies that apply DCA methods to wells in an unbiased, systematic, intelligent, and automated fashion.
Stress Dependence of Sandstone Electrical Properties and Deviations From Archie’s Law
The resistivity index (RI) of Fontainebleau and Bentheimer sandstones was investigated at ambient and reservoir pressures down to low water saturations. The RI measurements show that both sandstones display Archie behavior at elevated pressure.
Removing Fines-Migration Formation Damage in the Putumayo Basin in Colombia
This paper summarizes a wide variety of sandstone-acid-stimulation case histories, highlighting aspects such as mechanical conditions and operational practices.
Sandstone-Acidizing System Eliminates Need for Preflush and Post-Flush Stages
This paper presents experimental and field-case studies with a sandstone-acidizing treatment designed to retard the hydrofluoric acid reaction rate and enable single-stage treatment.
Acidizing a Sandstone Formation Successfully in the Gulf of Cambay
This paper describes a matrix-acidizing campaign executed successfully in the Gulf of Cambay on the west coast of India.
