GA, HB, JD, KE, LF, MG, and OI are the major reservoirs.

Retarded mud acid treatment as needed for formation damage.

Induction electric logs (SP, GR, resistivity) + sonic, FDC-CNL, dipmeter, sidewall cores.

Routine wireline sidewall cores; drill-stem testing in major sands; conventional coring in selected wells & intervals; pressure transient analysis.

Surface to TD: monitor total gas, rate of penetration, pressure, chlorides, & shale densities; catch cuttings, gas chromatography.
