Conoco tests

The best scientific study comparing the LWD logs with the wireline logs has been done in the framework of a project sponsored by the oil and service companies in Conoco test facility, Kay County, Oklahoma in 1990. 

Before the individual pieces of equipment are started, they should be checked out. Conoco, as part of its prestartup procedure, sent observers to the manufacturer s plant to observe the fabrication and to test the equipment before it was shipped. They found, among other things, at least 5 pumps with defective seals. These errors were corrected by the vendor before the items were shipped. This checking was in addition to checks performed during the construction phase. 

In order to overcome these problems, the flow schemes as shown in Figures 1 and 2 were developed. These incorporate the use of Kerr-McGee Corporation s Critical Solvent Deashing and Fractionation Process (CSD) for recovery of the SRC. The Kerr-McGee Process adds extra flexibility since this process can recover heavy solvent for recycle, which is not recoverable by vacuum distillation. EPRI contracted with Conoco Coal Development Company (CCDC) and Kerr-McGee Corporation in 1977-1978 to test these process concepts on continuous bench-scale units. A complementary effort would be made at the Wilsonville Pilot Plant under joint sponsorship by EPRI, DOE, and Kerr-McGee Corporation. This paper presents some of the initial findings. 

A few LNG spill tests on organic liquids carried out at Conoco by Yang (1973) led to reproducible explosions. When saturated hydrocarbons from Cj through Cg (including many isomers) were used, immediate explosions were noted. Delays of 5 sec or longer were recorded before they occurred on methanol, acetone, or methyl ethyl ketone. Few or none were recorded for higher alcohols or for hydrocarbons above Cg (or benzene). 

Both Phillips and UOP have employed additives dissolved in the liquid HF. The objective is to reduce the tendency to form, as a result of an accident, highly toxic aerosol clouds. Claims have been made that the additives reduce the amount of the HF that enters such a cloud by 65-90%. Although such a reduction is obviously important, no information is available on the hazards that still exist or how far toxic levels of HF might still be transferred. The additives eventually need to be separated, recovered, and recycled. The concentrations of the additives in the HF have apparently not been reported in any detail. Additives increase operating costs significantly. Somewhat high-quality alkylates are, however, produced in at least some cases when additives are used. Conoco-Phillips use sulfolane as their additive while UOP has tested both pyridine and picolene. These additives likely form hydrogen bonds with HF, and also affect the interfacial areas of the dispersions. 

Phase II - Pilot Plant Testing. This phase of coal gasification materials evaluation involves exposure of metals and refractories in selected test locations in current pilot plants. Corrosion testing in this effort began during 1974 with four pilot plants and now involves six HYGAS, CONOCO COAL, Synthane, BI-GAS, Steam-Iron, and Battelle. 

Two exposures have been completed in both the CONOCO COAL gasifier and regenerator. Linearly extrapolated corrosion rates for selected alloys exposed in these CONOCO COAL test locations are presented in Figs. 

The objective of this paper is to present Conoco s current methodology for the systematic evaluation of different gel systems for permeability modification. First, the beaker and core test techniques used in the evaluation of gel systems are reviewed. Then, the experimental approach followed for a complete gel evaluation is discussed. Laboratory results are included in this discussion to Illustrate the Importance of the various steps in the evaluation process. In addition to the general overview of our testing program, results are presented that demonstrate the usefulness of the beaker tests in identifying trends observed in core tests.
