GREEN CHEMISTRY FOR SOUR GAS WELLS
The well treated here produces sour gas with 14 mol% H2S and 9 mol% CO2 at a bottomhole temperature of 135°C. Therefore, the tubular consists of L-80 with some internals made of Incoloy 925 and alloy 28.
For the removal of residual scales in the tubing shoe section of this horizontal well, we used our biodegradable acid system SSB-007. Prior to the actual job, the extreme low corrosivity of SSB-007 was confirmed via intensive lab testing with an environmental-friendly corrosion inhibitor.
5 m3 of this state-of-the-art treatment fluid were pumped through tubing and displaced employing a booster unit with natural gas. According to our customer, the performance of this application was satisfactory, thus establishing SSB-007 to their standard system for acidizing sour gas wells.

MANY CHALLENGES: ONE PARTNER
We proudly announce that our 7 5⁄8′′ x 9 5⁄8′′ LINER HANGER application was a complete success. Here, the vast experience of our DOWNHOLE TOOLS team was an essential factor for this positive outcome. In this context, we pumped a specially customized light-weight cement slurry at a density of 1.4 kg/L. Through many applications, this system has already been established for CEMENTING geothermal, as well as oil & gas wells.
For effective loss zone isolation, we additionally employed two 5 1⁄2′′ INFLATABLE PACKERS in the openhole section of the well. After finishing the job, the upper inflatable packer was successfully retrieved. The extremely short mobilization time was further testimony for our trademarks: FLEXIBILITY, RELIABILITY AND CUSTOMER ORIENTATION.

1.20 SG HOZLITE SLURRY –IDEAL FOR PREVENTINGLOSSES IN WEAK FORMATIONS
During cementing three oil wells in France, we encountered the challenge of low fracture gradient and consequently potential losses into the formation. For proper zonal isolation combined with strong mechanical properties, we successfully employed a 1.20 SG HOZlite slurry. For further information, please feel free to contact us directly.
HIGH-DENSITY CEMENT SLURRY FOR GEOTHERMAL PROJECTS
Fangmann Energy Services has successfully cemented a 7” liner employing its customized heavy weight slurry of 2.15kg/L –one of the highest densities pumped in Europe; if not the highest ever used for cementing a liner in a geothermal well. For more information, please feel free to contact us anytime.
THREE-STAGE CEMENTING OPERATION FOR GEOTHERMAL WELL
It is distinctly seldomthat geothermal energy clients call for specially customized solutionsto cement a string at shoe + top intervalonly. The reasonbehind wasto allow future testing and production from a formationlayer situated in between. To addressthischallenge, Fangmann Energy Servicesprovided an innovative casing hardware setting, comprising a TAM CAP and double-staged elements positioned at specific intervals. In thisway, employinga five-plugsequence, exact placement of the cement slurry was possible.
