The invention relates to a procedure for the admixture of silicon oxide to a hydraulic cement slurry, particularly for well cementing, and is characterized by amorphus silica with particles smaller than 1 micro-metre being mixed with water to a liquid micro-silica, silica flour with particles from 2 to 200 micro-metres being mixed in said liquid micro-silica and the thereby obtained silica ...
Optimum Casing centralization in the open hole section should aim for at least 70%. Before Cementing Casing Before start of the Primary cement job operations, condition the mud to at least the original specifications, bringing down mud PV to about 30 mPa.s and YP to about 10. Gel strength of the mud should be as low as possible and not progressive.
Drl & Rig Eqpt ratings: ... That is a pretty straightforward procedure and takes only a few minutes to do. The only point of difficulty in the procedure is deciding on the magnitude of the design factors to use. ... Once flow has stopped, operations that follow, casing and cement must be suitably placed to set, and seal the annulus zone for ...
Casing Cementing Primary cementing is the introduction of cementacious material into the annulus between casing and openhole to: Provide zonal isolation, Support axial load of casing string and other strings to be run later, Provide casing protection against corrosion, Support the borehole, Secondary cementing or Remedial jobs:
1- Design and execute different types of cement job for drilling and work over rigs. 2- Inventory control and COGS management. 3- Operate multi type of stage tools ( + 100 job done successfully) 4- Develop local best practices procedures related to cementing. 5- Lead in introducing new technology tailor to customer challenge.
- Execution of casing cementing programs and calculating cement and mud volumes required for the job; - Optimize drilling hydraulics and monitor real time drilling parameters; - In case of kick situations follow company's procedure in cooperation with rig contractor's; - Well Control - Killing gas wells with 3, 5 …
This prevents casing splitting and virtually eliminates cement cracking. Little casing damage occurs with conventional bullet guns. Jet guns with exposed charges, such as strip or capsule type guns, can cause deformation, splitting, and rupture of the casing, and appreciable cracking of cement.

Production casing may be exposed to loads associated with other tubulars, particularly the production tubing:. Hydrostatic-set packers (see Section 12.6.3.3 and the loads illustrated in Table 12.8) are installed by pressurizing the entire tubing/production casing chamber.Depending on the particular packer, the production casing can be exposed to significant internal pressure.
