THE Chairman opened the session by indicating the arrangement it was proposed to make for the presentation of the papers and for their discussion. As he said, production covered a very wide sphere and it would be impossible to do justice to the subject in the time per mitted, or in the papers with their limited length. He informed the meeting that the papers did not by any means cover even the major problems which confronted this side of the industry. There were thirteen papers, and these had been arranged in five sections in order to facilitate their presentation and discussion. The arrangement of the five sections was in what might be considered the natural sequence, starting with the theoretical aspect of the problem, then proceeding on to the second section dealing with the collection and investigation of data from the reservoir fluids themselves. The third section dealt with generalised production problems and focussed attention on various aspects. In the fourth section had been placed those papers dealing with artificial methods of lifting oil to the surface; and in the fifth section an important paper dealing with the treatment of crude oil emulsions had been submitted. He proposed during the morning session to present, or have presented, the papers in the first three subdivisions, and to devote the afternoon session to the fourth and fifth subdivisions.
He informed the meeting that they were fortunate in having the authors of several of the papers present. Professor Dr. Versluys of Amsterdam was, he said, too well known to introduce to.the meeting, and he doubted whether there was anyone present who had not read Professor Versluys' published works. He proposed to call on Professor Versluys to indicate the important features of his paper, and perhaps in addition to speak to the Congress of some of the other researches on which he was a recognised authority. In addition, a paper by Mr. Frank Dabell had been placed in the first section.
Unfortunately, he, the Chairman, had not had an opportunity of studying this paper, as it had not been received in time to be printed, so that he would have to ask Mr. Dabell, who was present, to indicate the main features.
In the second section they had three papers dealing. with the collection and application of data from bottomhole samples. Fortunately two of the authors, Captain Comins and Mr. Pym, were present and would be able to introduce their own papers.
In the third section -the authors were abroad and he proposed to present these papers.
At the opening of the afternoon session the Chairman informed those present that he had been requested to continue the morning's discussion and not to commence with the papers on lifting methods until further opportunity for discussion had b
