At the Oil and Gas Institute - National Research Institute, research works were undertaken in order to solidify drilling-related waste with the use of Portland cement CEM I 32,5R, hydraulic binder SCQ 25, as well as an additive of sodium water glass fulfilling a function of the binding activator. The paper presents the optimal methods of management of drilling-related waste containing the remains of drilling fluid. Attempts of solidification were conducted according to the bases of operation of modern waste management, taking into account the possible harmfulness of the generated waste on the environment. The test material was the drilling-related waste from B-1 and P-1 opening drilled with the use of bentonite drilling fluid and salted polymer-potassium drilling fluid, while the disposal through solidification was conducted by offering a new technology of solidification developed at INiG - PIB with the use of binding agents selected based on laboratory tests (sodium water glass + additives of hydraulic binder / Portland cement CEM I 32,5R as well as the SCQ 25 binder). The obtained results of the analyses of leachability of harmful substances after solidification of drilling waste prove that the solidified samples do not meet the criteria for acceptance of the obtained semi-finished products to be deposited at a landfill. This is associated with exceeding the acceptable content of dissolved organic carbon (DOC), despite the fact that the obtained (TDS) and remaining indicators were within the range acceptable by the standard. The presented method of immobilization of drilling-related waste allows properly selecting the quantitative and qualitative composition of immobilizing agents in the future.
