Conceptual, organizational and technical solutions proposed concerning drilling cuttings disposal during the well construction in offshore territories

Introduction. The problem of ensuring environmental safety associated with the formation of drilling waste during field development is relevant all over the world. The accumulation of large volumes of drilling waste leads to the need to find alternative ways to dispose of this type of waste. The accumulation of high drilling waste volumes leads to the necessity of searching for alternative waste disposal methods used in practice. Its transformation into a secondary raw material resource can be the one.

Aim. Improving the environmental situation, ensuring the environmental safety of the areas of development of offshore hydrocarbon deposits and the waters of ports through the processing of drilling sludge.

Materials and methods. The methodology of studying samples of drilling mud and soil mixtures for the study of chemical, toxicological and physico-mechanical properties included a complex of theoretical, experimental and bench studies, including: granulometry, petrography, electron microscopy, biotesting. Mathematical and statistical methods were used to process the research results.

Results. In this paper, a conceptual technological scheme for the preparation of solid drilling waste to be used as a basis for the production of building materials is proposed as an option. The main technological solutions for processing are focused on obtaining products using as building materials «in the field» — to strengthen the slopes inside oil field roads and cluster pads, in low-rise construction including enclosing structures, ancillary buildings, etc.

Conclusion. This research determined that during the preparation of cuttings for disposal, the volume of transportation of drilling waste is signifi cantly reduced leading to the possibility of its disposal both on the platform and on the coastal base as part of raw materials for the production of building materials.
