Abstract: Currently, the biggest concern of different industries is the disposal of waste generated. The liquid effluents in general have more elaborate studies realizing alternatives for their treatment by reducing their toxicity or changing specifications for a return to the process, an internal recycling or even studying alternatives for recycling outside. In the case of solid waste, there are many papers on reuse. In general, the studies involve alternatives to reduce the possible toxicity and subsequent disposal. In some cases, the studies dealt with the residue already involve their use as material for construction (bricks). This work aims to evaluate two types of waste, namely, the drilling mud to clay-based generated by the activity of exploration and exploitation of oil and solid waste generated in the production process and catalyst for fluid catalytic cracking plant. In both cases, is currently the destination for industrial landfills, and the generating unit has to bear all expenses related to material handling. Our purpose in studying this waste, will initially study the temperature profiles. The dry material being ground and with a pre-determined size will be tested for physical-chemical, such as X-ray fluorescence (XRF) to see the composition and ASAP to analyze the surface area and pore volume. With this material treated in bench tests will be performed to assess the capability of removing nitrogen and sulfur contaminants in lighter fractions of petroleum. Preliminary tests with the industrial base of sorbent clay and zeolite showed a good result. These tests serve as a basis for comparison with material obtained in the laboratory.

Abstract: This paperexplainedthe use ofsolventnon-reactive technique with catalyst based on solution polymerization. The polymerization of Lignin as a raw material could produce a new compound as Lignin Graft Copolymer (LGC) which can be used in oilfield operation to solve fluid loss problems. In this technique, Lignin polymerize with superabsorbent polymer (SAP) using different parameters such as; heat, staring, time, and amount of catalyst. The Lignin was extracted from soda pulping process of Oil Palm Empty Fruit Bunch (OPEFB) long fibers. Lignin functional groups were characterized using Fourier TransformInfrared(FT-IR) spectroscopy.This product required further laboratory experiments to enhance its industrial applicability as a drilling fluid reducer.

Abstract: In oil drilling the failures of PDC drill bits are exhibited as erosive wear, dropping and breaking of cutters, so the erosion and corrosion resistance of the matrix is one of the key factors affecting the quality of PDC bits. In order to understand the degradation mechanism of matrix materials for drill bits, a kind of loop recirculation rig is adopted to measure total mass loss TML, mass loss E by pure mechanical erosion, and then through calculation the mass loss C+S by corrosion and synergy is obtained. The tested and calculated results show that TML of matrix materials is not only caused by pure mechanical erosion, but also by corrosion and their synergy of mechanical erosion and corrosion. In the discussed scope of this paper the volume loss produced by corrosion and synergy is 24.16% of the total volume loss (TVL) at most, which tells us that the corrosion resistance of matrix materials should be considered carefully besides their erosive resistance in the design and selection of PDC drill bits used in the corrosive drilling muds.
