Research & Development Department P. 0. Box 579^ Niagara Falls, N.Y. July 2k, 1968 MEMORANDUM SUBJECT: Drilling Fluids - Vlsbestos (S-G200) and Supervestos (S-G210) Should Make Good Additives in Clear Packer Fluids, Namely, Salt Solutions FROM: E. J. Markiewicz (l)"Packer fluids are those fluids, either clay-laden or without solids, which are left in the annular space between the tubing and casing. The primary purpose of a packer fluid is to maintain fluid pressure on the casing interior and tubing exterior for the purpose of preventing the development of potentially danger ous pressures on the casing." In reviewing potential Calidria applications, my memorandum dated September 27, 1967 clearly shows the effect of High Purity Asbestos in five salt solutions. With all our experience and data, there is no reason why we cannot apply S-G200 and S-G210 to these salt systems in drilling fluids. Possibly we should furnish this information to Montello, Inc. for their field sales and development. We could evaluate S-G200 and S-G210 in applicable salt solutions as the information is re quired. We may also supply samples of these slurries for the A.I.M.E. display Montello is attending in September. In summary, S-G200 and S-G210 should be compatible in clear packer fluids. EJM:dnrp f EV J.

These are: First paragraph, line 3-4 - reads "electropositive" This should read "electronegative" First paragraph, line 7 reads "Vanadye". Should read "Vanadyl" Also page 3, line 2 If it is not too late, could these be corrected prior to issuance by your department. Very .truly yours. RGW/bsn R. G, Woolery A 17293 R- O. Me W.E.Ko!. A.

August 2, 1568 MEMORANDUM SUBJECT: Repulpability of Asbestos: Dispersibility of Asbestos Pellets in Aqueous Systems FROM: E. J. Markiewicz Program goals and objectives are covered in ny memorandums of September 27, 1967 and July 10, 1968. To reiterate, an easily repulped pellet must be supplied to our customers to be repulped in their existing equipment. The laboratory data attached show the various reagents that will aid in repulpability of Calidria asbestos pellets. S-G200 was used for all tests since ve are presently concerned with supplying Montello, Inc. customers with repulpaole S-G200. All repulping was done with a small laboratory-size magnetic stirrer. Cur previous repulping problems have been discouraging only- in the respect that customer and our approach to repulping missed one point. Mixing and repulping are defeated in any system that does not use proper baffling to control fluid flow to the point of agitation. The A.P.I. standard mixing cup should be baffled either at its base (the easiest method) or furnished with one obliquely mounted baffle similar to the baffles in the Hermann disintegrator mixing vessel. This was easily proved in the laboratory since all repulping done for this memorandum was with a magnetic stirrer utilizing one baffle. All pulping was done for only a period of 7 minutes except for Test 6 which was baroid filtered and needed 12 minutes of pulping time. The S-G200 pellets even repulped sufficiently for drilling fluid application. All our procedures were concerned with peripheral speed and not with the fluid flow to maximize the energy input. These repulped products would meet the +65 mesh per cent retained test, but 100 mesh was picked to encourage our per cent repulpable material to meet a <1% + 100 mesh value. The wet attrition circuit at King City with the present set up or very little modification could meet this quality control specification easily. In summary, we could supply a more easily repulpable pellet, but we face problems of filtration, extrusion, and drying which could be answered by our pilot plant operation in Building 158. We also must examine the compatibility of the re pulpable pellet in the drilling fluid system and the paper systems for K.P.P. A 17296 Memo re Repuipability of Asbestos: Dispersibility of Asbestos Pellets in Aqueous Systems 2 August 2, 1963 An interesting aspect from this study is the potential of producing specialty products that are more amenable to drilling fluid and paper mill systems. We could sell experimental tonnage shipments from Niagara which should help offset any expense this might entail. Also, we could furnish data to King City for plant production and the parameters involved. EJM:dmp Attach. E.'J.
