Inorganic and Organic Water Quality Studies

Property Transfer Audits

Additional Services Offered:

Cuttings Gas Analysis - A low cost and simple method for detecting the relative amount of gas trapped within a low permeability rock. A measured volume of cuttings and water is placed into a commercial blender (identical to blenders used for culinary purposes) modified with a tube in the cap.  The blender is activated, and partly disaggregates the sample, releasing any gases still trapped within the cuttings.  The tube in the cap of the blender feeds any released gas to a gas detector. The cuttings gas readings are recorded, and placed on the logs at the appropriate lagged depth.  The cuttings gas readings are useful for determining the contribution of bit-liberated gas to the total gas curve.

Colorimetry - The process of grinding and measuring samples using specialized equipment to help in identifying areas rich in TOC. This data is assigned a curve column and is plotted on the mud logs with the gamma curve. These services are normally performed remotely using transported samples in a controlled laboratory environment. "Live" processing is also done on location at times when the formations are uncertain and the client is not sure of where they are at in the hole.

Calcimtry -  a calcimeter is used to determine the amount of carbonate minerals present in a sample. Calcimetry data can be useful for a variety of reasons, but it is especially useful for determining the carbonate content of shale formations and subtle 17 facies changes. A calcimeter consists of a chamber in which a weighed sample of dried and powdered cuttings is placed, along with a small vessel of hydrochloric acid. The chamber is isolated with a lid containing a pressure gauge or pressure transducer, and sealed. After confirming that no acid has spilled on the sample during the isolating and sealing process, the chamber is tilted and the acid allowed to dissolve any carbonate minerals The dissolution process results in release of carbon dioxide, and the resulting pressure is read and recorded. By normalizing the weight of the sample to one gram the pressure can be normalized. Using calibration information for the particular calcimeter the amount of carbonate minerals can be determined. If more than one carbonate type is present then they can be determined separately using the values from the multiple pressure peaks and formulas supplied by the instrument manufacturer.
