Quality Control and Assurance

Services we provide

Resolution drives results, and high-resolution data is critical to the identification of structural trends, geologic boundaries, and key features. No one takes this more to heart than PGW,  as our advanced workflow was developed in-house and tailored to each individual survey. This ensures that you obtain the highest quality data right in the field to keep your overall costs down.

PGW’s Quality Control approach incorporates:

  1. Pre-survey calibrations - We review all required pre-survey calibrations at predetermined sites prior to authorizing mobilization of the survey crew and system.
  2. Data acquisition - We review all ongoing calibrations and tests, review all acquired data, designate reflights when necessary, and authorize demobilization of the survey crew once all data are accepted. PGW carries out a range of proprietary analyses in addition to the standard tests to optimize data quality and works with the contractor to modify the acquisition parameters for local conditions.
  3. Survey deliverables. We monitor and remain in contact with the contractor throughout the data compilation process and review all draft and final deliverables. This includes data interpretation and integration if required.

Over the past ten years, PGW conducted survey quality control of more than 4 million line kilometers of data on surveys ranging in all sizes from small-scale (Ontario Geological Survey, Lesotho) to large-scale (Nigeria, Uganda, Saudi Arabia), to country-wide (Botswana, Togo).


  • PGW aims to be your partner in discovery using geological knowledge to enhance and constrain the geophysical interpretation of your data.
