Stimulation services and fracturing services
Our single or multiple fracturing stimulation uses coiled
tubing for wells with multiple or bypassed pay zones.
Jereh's Polymer- and solids-free fluids increase effective
fracture half-length to maximize fracture conductivity,
meanwhile Increase permeability and production
cost-effectively. We also offer real-time, on-site,
microseismic hydraulic-fracturing monitoring. Operators are
developing more difficult-to-access reservoirs and thin
formations that were previously uneconomical to produce.
Working with collaborator together, Jereh offers innovative,
cost-effective fracturing technologies to help achieve this
goal.
When surface pumping equipment pump liquid with higher
pressure than absorbency capacity of the formation, the
pressure nearby the well wall will be increased and exceed
the minimum crustal stress and tensile strength, thereby the
fracture is created in the formation. As liquid with
proppant is injected into the fracture, the fracture is
extended far-forth to form certain length, width and
height.As a result of high conductivity of created fracture,
oil and gas can flow into the well, which has played a role
of stimulation. |
1.Premium fracturing proppant
Select fracturing fluid technology should consider five
factors such as viscosity, liquid friction losses,
filtration, flowback and compatibility with reservoir rock
and fluid, the other two factors should be taken into
account and sources.
2.Optimum design of fractruing
Considering of the
maximum economic net present value, optimization fracturing
design generally include below three elements:
a.Daily oil & gas production under the different fracture
length and conductivity
b.Ensure the operation design of above fracture length and
conductivity includes dosage of fracturing liquid and
proppant, and sand adding procedure.
c.ombine above 1 & 2 to get fracture length basing on the
highest NPV |
3.Fracturing procedur
a. Separate-layer fracturing
b. high proppant concentration,Sand fallout on the end,
refracturing
c. Make use of artificial barrier layer to control
fracture height |
