Wireline logging was invented by Conrad Schlumberger in 1926. This I have confirmed from my copy of Petroleum Production Engineering (Uren 1924) which contains no references to wireline logging at all.
But oilfield standards have rightly changed over time, the above referenced book for example shows well control devices being fitted after a blow-out whereas BOPs are mandatory equipment today.
So I can confirm that up to 1926 cuttings were used to establish the presence of oil and reserves.
The SEC was established in 1934. I can find no evidence that cuttings have ever been accepted by the SEC to substantiate proven reserves.
A Society of Petroleum Engineers review of reserves reporting (December 2005) states:
- The SEC rules for proven oil reserves were established in 1978.
- Additional disclosure of probable and possible reserves is prohibited by the SEC.
- The SEC requirement for proven reserves is that a well test is mandatory and can be only avoided in the Gulf of Mexico (GOM) deep water if the estimate is fully supported by seismic, wire line conveyed sampling, logs and cores.
On a separate subject, the items in the 8K that Treaty advised the SEC they would do to properly integrate and produce the well are only half complete.
I hope Treaty progress the actions they need to do in Belize to: Prove (if) they have proven oil reserves; And if appropriate: Preparation of a development plan and EIA for oil production; Confirmation of a Commercial Discovery; Field development; Establishment of an oil export route, and Oil production.
I also hope that Treaty start employing Belizeans soon, as their current way of doing business with equipment and people imported from the USA iritates me and the Belizean people. BNE, who operate two oilfields is a significant local employer, provinding employing between 200 and 400 Belizeans.
