PGA Ltd is a geological consultancy based in Manchester, England, providing consulting services and multi-client studies, primarily on the Middle East, also on Onshore UK, the North Sea, Western Europe and Australia. The company has managed the production of all the Middle East Multi-Client Reports described on this website, principally under the supervision of Grenville Lunn. Grenville joined PGA in 1980 having obtained a BSc degree in geology and geophysics from the University of Leicester. He became manager of the PGA UK office in 1987 and managing director of PGA in 2014.

PGA Ltd was established in 1979 by Dr. John Scott. He served as managing director from 1979 to 2014 and continues to work as a consultant to the company. John holds a PhD in geology from the University of Reading and is also managing director of our sister company PGA Consultants Pty Ltd, based in Perth, Western Australia.

The areas of expertise on which our consulting work and multi-client studies are focused include regional exploration evaluations, sedimentological studies, petrophysical and exploration geochemical evaluations. In addition to the multi-client studies, PGA has undertaken consulting projects in the Middle East on SE Turkey, Bahrain, Jordan, Iraq, the U.A.E., Yemen and Egypt.


Quantock Geological Services was the trade name of Mick Storey. He died on 20 October 2002 in his 60th year. Mick was a consultant production geologist based in Taunton, England. He contributed to all the reports described on this website. His primarily responsible was for the regional stratigraphic framework, tectonic and structural summaries, and the organisation and interpretation of show, test and production data presented in the reports. He also supervised the lithological logging for the first geochemistry report. The group of geologists who have produced these reports will find it impossible to fill the gap that Mick leaves. He was our friend as well as our partner. His monument as a Middle East Geologist remains in the reports.


Saker Geological Services is the trade name of Dr. Augustus Wilson, a sedimentary petrologist and regional geologist based in Houston. Dr. Wilson has a PhD in geology from the University of North Carolina, and served as a postdoctoral fellow in computer applications at the Kansas Geological Survey. Later he was an exploration geologist in the Rocky mountains for Amerada Hess, and then worked for eight years for Aramco before resigning to become an independent consultant in 1982. A portion of this time with Aramco was spent in the regional geology group including working on the Aramco Arabian Basin source rock project (Ayres et al., 1982, AAPG) and later setting up and supervising a petrographic analysis group. Dr. Wilson undertook the petrographic logging for the majority of the wells in the petroleum geology reports and made the regional synthesis of the petrographic logs and other data.


The University of Reading provided access to the collection of well and outcrop samples upon which these reports are based. This collection, which we term the Middle East Archive, is largely composed of material collected by the Iraq Petroleum Company and includes samples from wells and outcrops in Iraq, Syria, Lebanon, Jordan, Palestine, Qatar, UAE, Oman, Yemen, Farasan Islands, Iran, Egypt, Turkey and Cyprus. The University recently sold this entire collection to a major oil company. In addition to access to samples the university has also provided certain analytical services to the projects including SEM and XRD analyses under the direction of Dr. Andrew Parker. The late Professor Bruce Sellwood produced the petrographic logs for several of the study wells.


Petra-Chem Limited undertook the geochemical analyses and interpretation for the report "Petroleum Geology and Geochemistry of the Middle East" under the direction of Trevor Doran and Dr. Sally Doran, who were both geochemists with British Petroleum and Palaeochem Limited, prior to forming Petra-Chem Limited.

Petra-Chem Limited have completed multi-client and single-client studies on the UK and world-wide, including, in the Middle East area, Jordan and Turkey.
