         148 . A method of recovering water from SAG-D slop oil comprising:
 mixing a first quantity of water with a first quantity of a chemical blend to create a water/chemical mixture, the chemical blend comprising: (i) Malcera 508MM and Malcera 1507AK (ii) acceptable alternatives to Malcera 508MM and Malcera 1507AK mentioned herein (iii) Malcera 508MM and acceptable alternatives to Malcera 1507AK mentioned herein or (iv) acceptable alternatives to Malcera 508MM mentioned herein and Malcera 1507AK;   heating and stirring the water/chemical mixture;   adding to the mixture SAG-D slop oil create a water/chemical/slop oil mixture;   heating the water/chemical/slop oil mixture; and   separating individually the water, the oil, and solids from the water/chemical/slop oil mixture.   
     
     
         149 . The method of  claim 148 , wherein the water/chemical mixture is heated and stirred until the mixture reaches about 50-70 degrees C. and the water/chemical/slop oil mixture is heated until the mixture reaches about 50-100 degrees C. 
     
     
         150 . The method of  claim 148 , wherein the water/chemical mixture is heated and stirred for about 10-30 minutes and the water/chemical/slop oil mixture is heated for about 30-60 minutes. 
     
     
         151 . The method of  claim 148 , wherein the chemical blend comprises Malcera 508MM and Malcera 1507AK. 
     
     
         152 . The method of  claim 151 , wherein the chemical blend comprises at least 0.010% Malcera 508MM and at least 0.03% Malcera 1507AK. 
     
     
         153 . The method of  claim 151 , wherein the chemical blend comprises 0.010-0.25% Malcera 508MM and 0.030-0.5% Malcera 1507AK. 
     
     
         154 . The method of  claim 148 , wherein the chemical blend comprises acceptable alternatives to Malcera 508MM and Malcera 1507AK mentioned herein. 
     
     
         155 . The method of  claim 154 , wherein the chemical blend comprises 0.010-0.50% Malcera 508MM alternative and 0.03-0.50% Malcera 1507AK alternative. 
     
     
         156 . The method of  claim 154 , wherein the chemical blend comprises 0.05-0.25% Malcera 508MM alternative and 0.1-0.5% Malcera 1507AK alternative. 
     
     
         157 . The method of  claim 154 , wherein the chemical blend comprises 0.075-0.12% Malcera 508MM alternative and 0.25-0.4% Malcera 1507AK alternative. 
     
     
         158 . A process for cleaning drill cuttings comprising:
 to a first quantity of OBDC containing solids and oil adding 0.05-3.0% by volume of a first chemical blend with stirring and heating to create a mixture of OBDC and chemical blend;   to this mixture adding with stirring and heating a quantity of diluent which is approximately the same as the first quantity and 0.05-3.0% by volume of a second chemical blend to create a diluent/OBDC/chemical mixture;   stirring the diluent/OBDC/chemical mixture for a period of at least one hour at a temperature of not less than 150 and not higher than 185 degrees F. (66-85 degrees C.);   allowing the diluent/OBDC/chemical mixture to cool down to room (ambient) temperature (about 70-90 degrees F. (21-32 degrees C.)), wherein,   the first chemical blend comprises at least one blend from the group consisting of Malcera 508MM and a Malcera 508MM alternative, and the second chemical blend comprises at least one blend from the group consisting of Malcera 1507AK and a Malcera 1507AK alternative.   
     
     
         159 . The process of  claim 158 , wherein about 2.0% of the first chemical blend is used and about 2.0% of the second chemical blend is used. 
     
     
         160 . A composition including the ingredients listed in Rows 1-12 of Column 1 and/or Column 2 of Table 2 in the specification, wherein at least one ingredient is included from each row.
