Next Meeting :

Date: Thursday February 11th, 2009

Speaker: Sami Eyuboglu, PhD., Principal Scientist Sperry Drilling Services

Dr. Sami Eyuboglu is a principal scientist for Halliburton Energy Services in the Formation Evaluation group. He received a PhD degree from University of Arkansas at Little Rock and worked for the Ohio State University as a research professor. He joined Halliburton in 2008.

Topic: "NEW NON-INVASIVE SAMPLE CHAMBER TESTING METHODS CONFIRM DOWNHOLE SENSOR MEASUREMENTS AND VERIFY SAMPLE QUALITY"

While much attention has been given to the downhole determination of the quality and contamination levels of samples obtained using wireline pumpout formation testers, this paper addresses sample quality verification when samples are brought to the surface. It also presents new, non-invasive measurements of samples after their extraction from their carrier. This technology enables fluid identification and verification of the sample quality to ensure that the sample integrity has been maintained. It also enables wellsite decisions to be made regarding which samples are the most representative before they are shipped for additional PVT lab testing. This paper discusses a new sample chamber design that enables the precise measurement of the sample volume in the chamber while applying pressure to the sample. From these measurements, an accurate determination of sample density and compressibility can be made without opening the sample bottles. These measurements can be performed on standard sample chambers, as well as on nitrogen-compensated chambers. They can be compared with downhole fluid ID sensor measurements to verify that the sample properties and contamination are as expected. To demonstrate the utility of these new measurements, a range of field examples are presented that include water, oil, and gas samples in the presence of varying oil- and water-based mud contamination. In addition to comparisons with downhole measurements, the new surface measurements can be compared to subsequent laboratory measurements.

President's Message:

Welcome to the February edition of the Lafayette Logger! I hope everyone’s Mardi Gras preparations are well underway. Don’t forget Valentine’s Day on February 14! One way to get some gift shopping done is to attend our monthly meeting and win the door prize. It is time to start considering candidates for our annual scholarship award. Our annual Golf Tournament generated enough funds for at least two scholarships this year. Applications are available on the Scholarship link below. Bob Peatross of Halliburton is the Chairman of the Scholarship Committee. The other members of the Scholarship Committee are Joe Beck of Halliburton and Dr. A. Hayatdavoudi of ULL. Completed application packages should be sent to the address on the application by April 1. Our talk this month will be delivered by Sami Eyuboglu who is with Halliburton. His topic will be “Non Invasive Testing of Downhole Fluid Samples.” Thanks to Baker Atlas for sponsoring the door prizes in January. Lauri Hardwick will be out for a couple of months for a surgery. We all wish her a complete and speedy recovery. Donna Adams with PathFinder has graciously agreed to fill in during Lauri’s absence. Please be sure to make a reservation with Donna Adams before noon on February 10th by email email Donna Adams .
