Depletion of the reservoir through normal production causes pressure drops across the fractures and perforations. The pressure drops can often result in damage due to:
• Scale formation from produced waters
• Organic depositions from the produced fluids
• Wettability alterations due to insufficient surfactant applications/loadings
• Emulsions from pH shifts
• Incompatible or contaminated base fluids
• Polymer damage sustained during the initial fracturing process from guar and polyacrylamide friction reducers
Hydraulic fracturing is a well stimulation technique used in shale reservoirs that forces water, chemicals and proppant into the formation. The mix is applied under high pressure to penetrate cracks and open or fracture new flow channels, allowing hydrocarbons to flow back into the well.

LATERALSCIENCE ENGINEERED COMPLETIONS
LATERALSCIENCE完井技术
C&J Energy Services’ LateralScience process provides a reliable, cost-effective answer product that delivers the information necessary for successful completion placement on every well. This value-added technique enables operators to engineer the completion design using existing drilling data on every completion, whether a new well or a refracture operation, resulting in significant productivity improvement without any significant increased cost or additional wellsite activity.
•Cost Effective
The LateralScience process uses existing drilling data to determine completion placement. No additional data acquisition costs are required.
•Efficient
Since existing drilling data is utilized to determine completion placement, no additional rig time, processes or equipment is needed. Operational efficiency, critical in today’s market, is maintained.
•Scalable
LateralScience’s straightforward workflow makes the process deployable in high volume, multi-well applications and delivers results reliably and accurately.
•Direct impact on your bottom line
Intelligent placement of the completion and perforations help increase production by accessing bypassed reserves in refracturing operations and optimizes your completions in new wells.
How is this accomplished?
LateralScience uses commonly available drilling measurements and mud motor parameters to derive Mechanical Specific Energy (MSE). The MSE parameter is a good proxy for Unconfined Compressive Strength, a valuable reservoir parameter commonly used in frac designs. The result is a facies-based answer product that enables the operator to position perforation clusters so that they breakdown at a common treating pressure, resulting in uniform fracture treatment within each frac stage.
To date, LateralScience has been applied successfully on over 100 wells. It is validated through comparison to openhole wireline logs and by comparing productivity to offsetting wells or additional wellsite activity.

Re-Con Stimulation Service
Pipe integrity issues can prevent high pressure treatments from being a viable option. When this is the case, C&J’s proven Re-Con Stimulation Service is the solution.
By cleaning the wellbore and subsequently cleaning the existing fractures, perforation and formation damage can be remediated without the possibility of damaging the casing. This treatment uses a diverting process that ensures a near complete diversion of the treatment across any size lateral. Utilizing the latest in advanced chemistries and several leading-edge technologies, we provide the highest probability of engineered success for each well treatment.
Acid Wash Service
Well performance is affected by many factors. Once production begins to decline, identifying the right solution is critical. Refracturing a well is often not necessary—acidizing to remove damage is often overlooked as a solution.
