The Good, the Bad & the Ugly of Fluid Systems by Thomas Welton, Shrieve Chemical Products
As horizontal wells get longer, the challenges of fluid selections increase. Fluid system formulations can vary widely depending upon the reservoir conditions and operational needs. The products required are evolving to meet these needs.
The products being highlighted have challenges since it is difficult to develop and deploy chemicals that function in a wide variety of temperatures and salinities while still maintaining ease of use, additive-additive compatibility, and cost effectiveness. First, selection and compromises made with gelling agent selection will be discussed along with the strengths and weaknesses of xanthan compared to other polymers available. Based on the results of these strengths and weaknesses, a product development case study will be provided that will focus on a high stability, blended polymer and its application. Second, different types of lubricants will be presented as well as performance characteristics. A field example will be provided of evaluating a new lubricant. This will be followed by a discussion of asset integrity chemistries along with an overview of biocide selection, compatibility, and handling best practices.
Finally, suggestions for designing fluid systems will be presented along with potential pitfalls and solutions for balancing performance goals, temperature, salinity, and additive-additive compatibilities of gelling agents, lubricants, and biocides.
