DME, Drilling Mud Emulsifier

Introduction

Emulsion based drilling fluids have emerged as an important class of drilling fluid systems, which have gained a significant interest in modern drilling operations. Oil-in-water (O/W) emulsion mud is widely used for low pressure and depleted oil and gas reservoirs.

The stabilization of the emulsion systems is achieved with the help of suitable surfactants. The polymers and bridging agents are used to control the rheological and filtration properties of the drilling fluid systems.

It is also important to pay attention to the environmental and waste disposal considerations of these drilling fluids at the drill site. So different Emulsions have been designed for this purpose.

DME is a mixture of special emulsifying agents which when used in drilling mud, gives a stable emulsion of oil in water. Water used for drilling mud may be fresh, potable, salty, or seawater.

DME is an emulsifier that is applied to water-based drilling mud when other convectional emulsifiers fail to emulsify diesel fuel in mud texture. It provides a uniform, stable, and durable emulsion in all tough conditions of oil well drilling.

Advantages

The use of DME can substantially enhance drilling efficiency and completion quality.
DME reduces the formation damage and allows trouble-free drilling under abnormally low reservoir pressure conditions.
DME increases production rates above those planned.
DME allows the use of conventional drilling equipment that does not require the time and cost of rig reconstruction, as is required in the case of oil-based mud (OBM)
DME is suitable for low porosity and permeability conditions.

Features

It creates excellent emulsion drop dispersion and system stability.
It gives a stable emulsion of oil in water.
It provides a uniform, stable, and durable emulsion in all tough conditions.

Packaging and Storage

DME is packaged in a 220-liter polyethylene or steel drum. Customized packaging is also available on request.

DME store in a dry, well-ventilated area. Keep the container closed. Keep away from heat, sparks, and flames. Store away from incompatibles. Follow safe warehousing practices regarding palletizing, banding, shrink-wrapping and/or stacking.

Shelf Life

DME has a shelf life of at least six months from the date of manufacture when stored in the original sealed containers in a cool and dry place.

Safety and Handling

DME must be handled as an industrial chemical, wearing protective equipment and observing the precautions as mentioned in the MSDS.
