Abstract
A method and system for drill cuttings analysis including collecting a sample, taking measurements and readings from the sample to provide data, and keeping a portion of sample for storage and/or future analysis. The sample is representative of the formation being drilled and the data may be correlated or indexed to the formation by time, gamma ray or otherwise. The data collection and analysis may be substantially continuous.

METHOD AND APPARATUS FOR ON-SITE DRILLING CUTTINGS ANALYSIS
FIELD OF THE INVENTION
[0001] The present invention relates generally to a method and system for drill cuttings analysis. More particularly, the present invention relates to a method and system for on site drill cuttings analysis while drilling.
BACKGROUND OF THE INVENTION
METHOD AND APPARATUS FOR ON-SITE DRILLING CUTTINGS ANALYSIS
FIELD OF THE INVENTION
[0001] The present invention relates generally to a method and system for drill cuttings analysis. More particularly, the present invention relates to a method and system for on site drill cuttings analysis while drilling.
BACKGROUND OF THE INVENTION
[0002] During drilling of sub-surface formations, drilling mud is circulated down the hole to flow up the drill bit cuttings. The cuttings are separated from the mud and then may be directed to an apparatus for further processing and measurements, for example as described by the author in US Patent # 6,386,026 "Cuttings Sample Catcher and Method of Use" and additionally disclosed in US Patent Application No. 10/711,333 "Drilling Cutting Analyzer System and Methods of Applications" (Published US 2005-0082468).
SUMMARY OF THE INVENTION
SUMMARY OF THE INVENTION
[0003] It is an object of the present invention to obviate or mitigate at least one disadvantage of previous systems for drilling cuttings data collection and analysis.
[0004] In general terms, in an active mud drilling system, drilling fluid (mud) is returned to surface containing drill cuttings generated at the cutting face of the drill bit. A
slipstream sample portion of the drilling mud containing drill cuttings is taken as representative of the drilling mud containing drill cuttings. The sample is conveyed to a portable analysis/collection system. The portable analysis/collection system may provide analysis and collection of the gas and the drilling cuttings. A wide range of analysis may be performed. A small representative sample is continuously or substantially continuously collected for storage and/or further analysis. The bulk of the slipstream is returned to the mud tanks for treatment/reuse/recycling/disposal. The data collected from analysis may be correlated to open hole logs, known geological markers or interfaces, and/or from the dept of the drill bit from where the drill cuttings were generated.

DETAILED DESCRIPTION
[0007] Generally, the present invention provides a method and system for drill cuttings analysis including collecting a sample, taking measurements and readings from the sample to provide data, and keeping a portion of sample for storage and/or future analysis.
The sample is representative of the formation being drilled and the data may be correlated or indexed to the formation by time, gamma ray or otherwise. The data collection and analysis may be substantially continuous.

The sample is representative of the formation being drilled and the data may be correlated or indexed to the formation by time, gamma ray or otherwise. The data collection and analysis may be substantially continuous.
1. MECHANICAL
[0008] During the drilling of a well, a portion of the drilling fluid (mud) returns containing drilling cuttings may be sampled (for example continuously, semi-continuously, or intermittently).
[0009] One particularly advantageous location for drawing the sample is at the possum belly (See Fig. 1). The sample is conveyed to a moveable analysis/collection system, for example through the use of a mud pump, for example using the methods and apparatus of US 10/907,485 CENTRIFUGAL PUMP WITH SCREW PUMP ACCELERATOR, US 11/945,095 and CA 2,612,392 CENTRIFUGAL PUMP WITH SCREW PUMP

[0010] Optionally, gases may be liberated and analyzed, for example using the methods and apparatus of US Patent No. 6,389,878 and CA 2,270,833 GAS TRAP for DRILLING MUD or otherwise.
[0011] The mechanical equipment may be conveniently housed in a portable building, vehicle mounted such as truck and/or trailer or skid mounted. Fig. 1 depicts an example of trailer mounted.
[0012] The sample stream may be analyzed to obtain a wide variety of measurements and a small sample may be retained for storage and subsequent further analysis or measurement.
[0013] The bulk of the sample stream is returned to the mud tank for processing/re-use/recycling/treatment/disposal.
