Graphical Solution Of Concentration At Production Wells Of Injected Radioactive Water Tracers, George E. Vaughn Jr.

Masters Theses

"With the advent of field research in which radioactive isotopes are used as tracers for water injected in secondary-recovery operations, knowledge of the probable transit time between wells of an injected tracer, its concentration at detection points, and the resultant optimum injection concentration has become important. Both detection and, consequently, injection concentrations of radioactive tracers are at least in part functions of the loss of tracer for various reasons, flow characteristics between wells, the rate of decay of radioactive emission, and the sensitivity of the detection apparatus. A method, based on the characteristics of a homogeneous 5-spot system, has been …

A Comparison Of The Effect Of Pvt Data Application Methods On Predicted Depletion Drive Reservoir Performance, Frederick A. Klein

Masters Theses

"It is generally agreed that the evolution of gas from oil within a reservoir is most closely approximated by the differential liberation process, while gas liberation in the flow string, surface separator, and stock tank is most nearly represented by flash liberation. To conform with this assumed physical behavior, appropriate application of both flash and differential liberation data in the computation of reservoir performance by material balance methods is indicated.

In this work, simple depletion-drive oil and gas recoveries were calculated (1) using differential liberation data only, and (2) using differential liberation data adjusted to incorporate the results of flash …
