Utilization of oil-based mud drilling cuttings

A large amount of oil-based mud drilling cuttings (OBMDC) are generated during shale gas extraction, which adversely affects the environment. In order to realize the resource utilization of waste, the High temperature and a large salt content weaken the surface hydration ability of clay particles in drilling fluid, reduce zeta potential, agglomerate clay particles, increase particle size, and destroy the stability of drilling mud. A filtrate reducer is required, therefore, to maintain the zeta potential of the clay, prevent the agglomeration of clay Synthesis and Evaluation of Betaine Copolymer Filtrate

Experimental investigation of the cementation and tensile

Cement sheath is an annular structure situated between casing and formation, which is designed to seal the formation and reinforce the borehole. However, owing to the surface irregularity and drilling mud residue, the interface between the cement sheath and the formation is one of the weakest parts for fluid leakage causing well Abstract. The innovative lightweight slurry 85 lb/ft3 (pounds per cubic foot) was prepared using three blended materials with a combination of 20% micro silica, 44% cenosphere and class-g cement, a special hydraulic binding material to forms strong bonding energy due to a combination of moderate sulphate-resistant and high sulphate Development of innovative lightweight slurry in oil well

1. Introduction. Well cementing is the most important operation during drilling and completion of oil and gas wells. A good cement job ensures efficient zonal isolation and protection of casing. 1,2 Based on prevailing wellbore conditions and cementing objectives, different admixtures are incorporated into the cement slurry design Coal fly ash (CFA) is a major global pollutant produced by thermal power plants during the generation of electricity. A significant amount of coal fly ash is dumped every year in the near vicinity of the thermal power plants, resulting in the spoilage of agricultural land.

‘Level-off’ cement plugging method to cure lost Springer

Controlling lost circulation during drilling operations in a reservoir prone to fluid losses is typically remedied by cement squeezing or plug setting as the last resort. The aim being to minimize or stop drilling fluid losses and to regain full returns at surface, and to maintain wellbore integrity. Different placement methods of cement plugs have been Naturally occurring radioactive materials (NORMs) and the presence of toxic metals in drilling fluids/their additives have raised research interests in recent times owing to the risks associated with the exposure times for drillers of petroleum wells. In this study, two drilling fluids A and B were formulated, while two other Mud Samples C and D Radiological and toxicity risk exposures of oil based mud:

Analysis of the Possibility of Using Cenospheres in the

Cenosphere-based cement composites have been tested at room temperature [51,52,53] and at high temperatures [48,54,55,56,57]. The concept of this research work included evaluating the possibility of using cenospheres as a cement substitute in the production of cement mortars. This research was also aimed at determining the influence ofDrilling waste has a significant effect on the water quality and the aquatic environment. Therefore, the harmless solidification treatment of drilling waste mud is important in terms of protecting the water environment.
