Mud Logging Quality Control

Mud logging is an integral aspect of the modern drilling process and is often the first and possibly earliest opportunity to detect hydrocarbon shows. As a result, it is crucial that the mud logging equipment used to monitor drilling is carefully calibrated and in proper working order. Ellington & Associates, Inc. therefore offers our services as a third party quality control analyst of the mud logging operations. Typically, our experienced staff of professional geologists and engineers actively participate from the pre-spud meetings through completion and evaluation.

At your request, our auditors will: Mudlogging

Ellington Receives ExxonMobil Production Company - US Production organization's Outstanding Service Award
"I am very pleased to take this opportunity to present you with ExxonMobil Production Company - US Production organization's Outstanding Service Award. This award is in recognition of your long record of excellent support of ExxonMobil's Mud Logging Audit program. Dr. Gorody's help in this effort is also being recognized and is likewise, deeply appreciated. This award was recently recreated to recognize significant contributions by various crews operating in our producing areas in the United States - both onshore and offshore. The award also includes wireline and LWD crews on occasion so it's for a pretty small and prestigious group of people. Ellington & Associates has been instrumental in ensuring that our mud logging units have been operating efficiently and most importantly, safely. Without your diligent and consistent effort to inspect our gas detection equipment, we would have less confidence in one of our simplest but most important formation-evaluation tools, the mud log."
