3. Planning for Drilling Fluid products:

iOG serves its clients by providing complete analyses on how drilling fluid products would behave in the downhole environment and optimize drilling performance to minimize the risk associated with fluids-related problems.

a. Drilling Fluid Systems & Products

iOG helps client in implementing drilling solutions that help out clients maximize Rate Of Penetration (ROP), eliminate Non-Productive Time (NPT), achieve QHSE performance objectives, and obtain quality data from the wellbore.

b. Completion Systems, Fluids & Tools

Our focus here is the safeguarding of well completions and formation stability by delivering techniques, technologies, fluids, tools and expertise that ensure the optimal condition of the wellbore and fluid systems.  Everything in our product line is rooted in our conviction that a clean wellbore, properly prepared, is the foundation for higher production and longer service over the life of your well.

c. Solids Control Systems & Products

One of the most effective ways to reduce drilling costs is to maintain drilling-fluid condition at an optimum level.  Controlling the amount and types of solids present in the fluid system, as well as fluid temperatures, can result in higher ROP, fewer lost-circulation problems and a reduction in well-control incidents.  iOG helps clients in using equipment and technologies that help our clients remove efficiency-robbing solids and keep the materials that boost productivity: lost-circulation and wellbore-strengthening products.

  • Performance of Modal Analysis to determine BHA deflected modal shapes.
  • Determination of the high solicited drillstring zones.

Our team replicates a real drilling operation in drilling software solutions dynamically and provides accuracy not possible with simpler steady-state models. The tool is then used in an Integrated environment for geoscience and drilling from well design to geosteering

Following are some of our offerings and applications of Drilling Simulation:

  • Simulation of all the aspects of Drilling operation, including the complex hydraulics involved, pressure control, well control, and blowout control.
  • Replication of drilling features like
  • Circulatory and Rotary systems,
  • Hoisting systems,
  • Blow-out prevention and Well Control system &
  • Downhole Effects

Geosteering is the process of continual adjustment of the placement of drillhead, taking into consideration the real-time changes and data coming from different sources about the immediate and surrounding areas to the drilling rig. Minimizing uncertainty and adopting a fit-for-purpose geosteering strategy is crucial to drilling productively. Real-time identification of reservoir layers enables directional drillers to adjust well trajectory to maximize reservoir exposure, even in thin, dipping, and fractured reservoirs.
