Chemical Tracer Flowback Data Help Understanding of Fluid ...

This paper presents a data set involving the pumping of multiple, unique chemical tracers into a single Wolfcamp B fracture stage. The goal of the tracer ,test, is to improve understanding of the ,flowback, characteristics of individually tagged ,fluid, and sand segments by adding another layer of granularity to a typical tracer-,flowback, report.

Description. Large amounts of aqueous based ,fluid, are used in hydraulic ,fracturing, of tight formations to enhance gas ,production,. The pumped aqueous-based ,fluid, is not fully recovered during ,flowback, of well after the treatment resulting in increased water saturation, water blockage, clay swelling, reduced relative permeability, and long-lasting formation damage that impedes gas ,production,.

Post-treatment ,production, tests often show only 30 - 100 ft of effective fracture length even for relatively large treatments designed for longer length. Not only is ,production, limited by these shorter-than-designed half-lengths; excessive fracture width combined with low closure stress often leads to serious sand ,production, problems.

However, the blank ,test, with the presence of a molecular sieve (without Ni and Fe) showed that the oxidative gel breaking effect of electrolytic brine on ,fracturing flowback fluid, was decreased with the addition of the molecular sieve, which was due to the introduction of potassium hydroxide in the molecular sieve preparation process and resulted in an alkaline surface of the molecular sieve.

Leonard24 evaluated the ,flowback, process by comprehensively using ,fluid, and proppant tracer ,test,, micro-seismic, records of pumping, ,production, logging, and ,production, data. Catlett et al 25 used hydrocarbon tracer technology to obtain oil ,production, for each ,fracturing, stage, and the reason for low ,production, was an-alyzed combined seismic data.

Volatile organic constituents have been shown to be present in fracturing fluid flowback wastes at levels that exceed drinking water standards. For example, testing of flowback samples from Texas have revealed concentrations of 1,2-Dichloroethane at 1,580 ppb, which is more than 316 times EPA’s Maximum Contaminant Level for 1,2-Dichloroethane in drinking water .
