Development of Instant Linear Gel for Coal Bed Methane Gas Operations| Stephy Publishers

Abstract: Previously we prepared fracturing linear gel with fossil
diesel, bio-diesel and also used suspending, anti-settling agents and
emulsifiers. But through this research, a novel and efficient method for the
preparation of linear gel directly mixed with water, guar gum and sodium
acetate together instantly. In this instead of diesel, we used water and no
need to mix anti-settling agents, suspending agents, emulsifiers that resulted
in 30 viscosity linear gel. Ammonium persulphate or Ammonium peroxidisulphate
and enzyme-G are used for oxidation purposes to break the gel gradually at a
particular static temperature. The degradation pattern observed from the
breaker test showed that a reduction in gel viscosity depends on time,
temperature & breaker concentration. Observations from experiments revealed
that a small concentration of breakers provides rapid break compared to
oxidative breakers. This article, designing of fracturing fluids describes how
to use the fluid's viscosity generated by the gelling agents like guar gum for
CBM operations.
Keywords: Breakers, CBM operation, Fragmentation, Linear gel,
Viscosity properties
Introduction
Hydraulic
fracturing typically involves millions of gallons of fluid that are pumped into
oil or gas wells at high pressure to create fractures in the rock formation
that allow oil or gas to flow from the fractures to the wellbore.1 The main
functions of fracturing fluids are to open the fracture and to transport
propping agents along the length of the fracture. They are four types of
fracturing i.e. water fracturing, gelled fluids, linear gels, crosslink gels.2
The chemistry of commonly used fracturing fluids and additives are guar Figure
1. Guar has a long polymer chain and high molecular weight Figure 2. Gymer
composed of Mannose and galactose sugars has a high affinity for water. When
the powder is added to water, the guar particles swell and hydrate, which means
the polymer molecules become associated with many water molecules and unfold
and extend out into the solution which tends to overlap and hinder motion,
which elevator the viscosity of the solution.
