About this Item
Black 12-ring binder gilt-titled to front 24x29cm. Approx (137)pp including Contents (1)pp, Legend and Explanation (4)pp, and logs for 65 wells of which 63 are (2)pp each and 2 are (3)pp each, printed single-sided in colour and b/w on facing pages. The binder is very good with handling marks, the interiors near fine with all logs present. This extremely rare and detailed in-house operational manual would have been used by IPC's geologists and managers. There is only one reference to it online (in Al Anzi et al, Siliciclastic Reservoirs of the Arabian Plate, AAPG, 2019, Chapter 7). The Contents are dated 23 October 1961 with each log dated individually during 1960-61, which facilitated regular replacement and updating when needed. The date is significant as it follows OPEC's creation (Sept 1960), and the enactment of Law 80 by Qasim's government which took 99.5% of the IPC concession without compensation, immediately halting exploration (12 Dec 1960). This did not affect Zubair and Kirkuk, but brought other territories under state control, with the Iraq National Oil Company formed in Feb 1964 to operate them. IPC came under increasing pressure in the 1960s, and was finally nationalised in 1972. The logs are arranged alphabetically from Adaiyah 1 to Zubair 38, each consisting of a Graphic Summary, and a Synopsis of Gas, Oil and Water shows. The Graphic Summary gives map reference, scale, spudding and completion dates and durations, total depth, objective, results, present status, details on production tests, and compilation date. The Synopsis features two geological sections with detailed annotations, one showing findings at each depth, the other based on the age of each "rock unit". An example from Kirkuk 116 - Objective: "Sited as a Cretaceous test on the Avanah dome of the Kirkuk structure. After testing the most promising intervals of the Cretaceous, drilling was continued to the limit of capacity without reaching the Jurassic". Result: "The Shiranish was not fractured and was dry. Heavy dark unproducible oil was found in the Mushorah. The Upper Qanchuga / Jawan was water-logged, with a small show of heavy gravity oil in its upper part. No production was obtained from the Lower Cretaceous". Present status: "Plugged to 3,525 feet, blanked-off and abandoned". Examples of production tests from other logs: "test failed", "no fluid ingress", "retaining valve leaked" etc. Seller Inventory # 4280
