AGIP-K and AGIP-M Hydrodynamic Logging and Formation Testing Equipment



  • Oil and gas open holes


  •  Oil and gas open holes
  •  Oil and gas cased wells



Tool modular design enable to operate in two modes:

1. formation testing in one trip, taking one representative sample of fluid with a volume of 500 mL and measuring reservoir pressure;    

2. hydrodynamic logging, involving multiple surveys (up to 40) of reservoir pressure;


- dual packer module, enabling to isolate the desired interval with two inflatable packers;

- optical fluid analyzer for separation of sampled fluids by its fractional composition;

- flow control module, flow rate monitoring during fluid sampling;

- pump-out module, providing fluid sampling out of formation and pumping it out into borehole;

- multisampler module, containing six chambers to take representative fluid samples for PVT-analysis;

- crystal quartz and piezometric pressure gauges – to measure reservoir and hydrostatic pressure;

- single-probe module, the probe being designed as side-wall pad

- multi-probe module, multiple probes being designed as side-wall pads, containing drawdown probe and two logging pressure probes: horizontal and vertical


  • Easy operation
  • Possibility to operate with any logging system produced in Russia
  • At the start of well stimulation, the maximum drawdown enables to recover residual fluid from the near zone of formation, which stay immobile in well operation, and further to evaluate reservoir saturation behavior based on it
  • Lifting of oil and gas samples to surface in a sampler
  • Cost of equipment and downhole services are 10-100 times less than similar foreign services
