CRITICAL COAL BED ANALYSES

� Borehole site Canister desorption

� Gas content analysis

� Desorbed gas composition

� Adsorption isotherm

Primary tool to quantify the volume and quality of gas to determine commercial potential.

Determines the total volume of gas present in a freshly cut reservoir sample(core)

Identifies the fractionation of gas over the life of desorption history to determine a total in situ gas composition and the need for multiple gas isotherm data.

Accurately determines the

volume of gas that can be stored in the pores through sorption at reservoir temperature and pressure.

• Global Tendering for three times and the set up could not be

procured

• Build up of AI set up suiting Indian geological conditions

through a CIL(R&D) funded project in association with IIT

Kharagpur

• Designing of the set up took time less than a year

• 70+ samples have been studied of coal/lignite fields

Shale Gas-Efforts seeded and Facilities developed

� Lab has recently created

facility for taking up Shale

Gas related studies

� A TOC test equipment has

been procured and is

working routinely for

measurement of inorganic carbon and organic carbon.

� TOC is the basic parametric

study to know the gas

potential in source rock in oil

and gas exploration

ROAD AHEAD The lab is fully geared up to take up detailed characterization

study of shale samples for shale gas potentiality

measurement.

� For the purpose, Rock Eval 6 – the most important

instrument for shale characterization is under advanced

stage of procurement.

� Porosimeter cum Permeameter for porosity and permeability measurement is in the process of

procurement.

� One instrument assembly to study shrinkage swelling

behaviour of coal/shale samples for recovery of methane from coal bed is under progress through a CIL (R&D)

funded project.

MINE AIR ANALYSIS

Page 30: CBM Laboratory Services - India CMM/CBM Clearinghousecmmclearinghouse.cmpdi.co.in/PresentationsNov13/... · CBM Lab Services: An Introduction Offers comprehensive and detailed analytical

Why is it required

� The firedamp of coal mines is chiefly methane.

Methane is combustible and mixtures of about 5-15% in air

are explosive

� Methane explosion occur when a buildup of the gas comes

into contact with a heat source.

� Hence it is desired to control the concentration of CH4 to

less than 1%.

� Mine air analysis will give the analytical data of

concentration methane which would ensure the safety in

mines.
