STAG Geological Services

ISO 9001: 2008 Quality Management Case Study Systems

STAG is recognised as a leading provider of practical solutions to

its expanding customer base of major multinationals & emerging independents worldwide.

STAG Geological Services Limited formed in 1995 with a small, select group of wellsite and operations geologists. Client companies appreciated the straightforward approach of Stag, and the competence of the personnel offered. Stag grew with the development of a training arm and the establishment of two lecture rooms as comfortable venues in newly built offices.


Dr Chris Bamber of OLC acting as quality consultant to STAG helped implement new quality practices and appointed third party assessors DNV to certify the newly developed quality management systems.


Building a quality system certified by DNV would be immediately recognised in the industry as a commitment to quality provision of geological services.

The Vision

To position STAG as a quality assured provider of geological services to the worldwide oil and gas industry.

The Process

OLC carried out an initial audit and gap analysis of the STAG Geological Services Ltd operational activities in Aldermaston, UK. This led the way for a process of developing a quality management system that satisfied ISO 9001: 2008 requirements. Firstly, the key process of STAG were identified and documented within a business system model which became the central tenet of their quality management manual.

OLC trained James Tidey in the skills of quality auditing and continuous improvement which in turn led to improvement of operations. After a period of systems development and consultation with OLC, the STAG quality management system was ready for third party assessment. The most appropriate of the certifying bodies for the industry STAG operated was considered as DNV. It was in January 2011 that the initial assessment was carried out and the certification visit was conducted in March of that year, leading to certification of STAG quality management system to ISO 9001: 2008 later that month.

The Benefits

The consulting process with OLC identified key areas of improvement for the business which led to certification, with DNV, of the STAG Geological Services Ltd quality management system within one year of the project start. STAG have confirmed their position within the oil and gas industry as leaders in the field of Geological Service provision.
