Short Course summary:

Surface Logging evolution in the 21st century- what data acquisition and analysis is now possible and what you should expect in terms of quality control. Three key facets of current surface logging practices will be illustrated and discussed with relevance to today’s oilfield. Case histories will be presented to show some practical application of these techniques.

Workshop outline:

Surface Logging Technology – Improvements and Quality Control.

Surface data is obtained as a by-product of drilling operations, with only a total loss of returns removing the data source. We will describe an overview of the technology improvements in drilling and formation evaluation technologies that have occurred in recent years. We have moved on from wheat-stone bridge circuits to newer technologies. What constitutes “good data”? What steps need to be taken to ensure the maximum amount of reliable information can be successfully gleaned from this “free” data source? Analysis and Interpretation are affected immensely by not performing the basics correctly.

Fluid Phase identification.

One of the primary formation evaluation uses of surface logging data has been the interpretation of downhole fluids from surface gas analyses. This subject that has been a focus for many operators to help reduce costs and “fill in the gaps” between direct physical measurements. We will review a range of techniques, highlight the steps needed to ensure the validity of the data and demonstrate some new technologies that now provide better answers at the wellsite. From gases (non-hydrocarbon and hydrocarbon) to liquids, including a new take on a very old technique.

Integrated Applications

We will finish the session with some real-world examples where multiple data sets have been integrated to provide valuable answers in a variety of different applications, that include open and drilling induced fracture identification, identification of reservoir compartmentalization and their connectivity and some useful seal effectiveness indicators. Not all solutions are needed for all wells, but by careful review, a significant amount of detail can be added to geological models. We can even apply some of these techniques to help drillers improve their performance.
