We’ve revolutionized the concept of displacements, actively analyzing recovered fluids, performing post-job analyses, and continuously improving upon mechanical tool designs.

Integration of all considerations—chemical (including spacer design), pit cleaning, filtration, mechanical, and hydraulic components—combine to remove all drilling fluid, residual mud solids, and mud film on the first attempt. This approach also creates a template to meet well cleanliness requirement as measured in common parameters of nephelometric turbidity units (NTUs) or percentages of solids (%v/v solids) of the effluent from the well during displacement.

From every standpoint—technical, financial, environmental—the M-I SWACO custom approach to displacement ensures that this critical operation is both successful for your operation and an improvement upon previous designs. Our cleanup tools prepare the casing, risers and BOPs while our filtration services produce meticulously clean completion fluids. Our software support is state-of-the-art and embraces fluid-flow dynamics for extra accuracy.

The services and equipment we supply are intended for increasingly complex well completions. Our integrated tools and services are used in combination to deliver new-concept displacements.

We offer:

• Cleanup and displacement chemicals
• Filtration of surface and downhole fluids
• VIRTUAL COMPLETION FLUIDS* software
• Torque reduction
• Specialty wellbore cleanup tools
• Specialty pit cleaning accessories
• Waste management throughout the entire process
• Post-displacement laboratory analysis

Spacer Chemistry

M-I SWACO excels at spacer chemistry design and possesses the largest data-based technology in the industry. We base our analysis on the reality of the thousands of displacement operations we have performed. We’ve applied our experience and learning to improve our engineering toolkit to model an effective spacer program that takes the restraints dictated by logistics and wellbore parameters into consideration.

Displacement spacers are tailor-made for case-specific applications according to the type of mud being displaced, the function of the individual spacer in the system and the volume of spacer that is required to provide adequate contact time at the specified pump rate.
