Title: Innovations of James J Dunlap in Downhole Technology

Introduction

James J Dunlap is a notable inventor based in Sugar Land, TX (US). He has made significant contributions to the field of downhole technology, holding a total of 2 patents. His work focuses on methods and apparatuses that enhance the efficiency and effectiveness of sampling formation fluids.

Latest Patents

Dunlap's latest patents include a "Downhole sampling apparatus and method for using same." This invention involves a method and apparatus for sampling formation fluid by drawing it from a subterranean formation into a downhole tool and collecting it in a sample chamber. An exit flow line is connected to the sample chamber, allowing for the selective removal of either contaminated or clean portions of the formation fluid. This innovation ensures that contamination is effectively managed during the sampling process.

Another significant patent is "Determining phase transition pressure of downhole retrograde condensate." This invention provides a method for determining the phase transition pressure of downhole retrograde condensate. It involves producing an OBM-contamination value from a time-series of fluorescence values, which are measured from a single-phase flow of OBM-contaminated formation fluid in a downhole cell. The process includes incrementing drawdown pressure and monitoring phase transitions, ultimately allowing for the determination of phase transition pressure values.
