Well Kick Simulation 

Well control simulation is a very useful tool for supporting well plan evaluation and drilling operation (Simulation While Drilling). We offer transient multiphase flow simulations of different blowout scenarios to identify and evaluate the well kick risk and determine the best ways to prevent well control incidents. The transient Simulation of Well kick involved the fully dynamic behaviour of the wellbore and near wellbore interaction with the reservoir. The outcome will assist operators to better plan a safe operation with optimised drilling parameters. 

Dynamic Kill simulation

The transient simulation is an essential method to prepare the contingency plan to control the well blowout risk as Dynamic Kill is a transient technique combining the static head of kill mud with frictional pressure losses in order to suppress the reservoir pressure and kill the blowout.

Dynamic Kill Analysis Features and Benefits
 

  • A variety of well control scenarios examined

  • Live graphics display visualization over the period of the dynamic kill operation

  • Engineering support for multiple kill scenario evaluation and modeling the Transient Simulation of the Dynamic Kill Analysis provides vital information to better prepared for well control Contingency Plan:

  • Dynamic kill pump rate

  • Kill fluid density

  • Minimum kill fluid volume

  • Dynamic kill pump pressure

Bottom-Hole Hydraulics Analysis  

Thermal-Hydraulics tools generate, model, optimise and develop accurate temperature and pressure profiles, downhole fluid behavior throughout the trajectory of the wellbore such that Bottom Hole Pressure (BHP) remains closer to the pore pressure. These tools also maintain narrow windows of drilling pressures between pore pressures and fracture gradient pressures. This increases borehole stability, lessons formation damage and avoids drilling fluid losses or gain.

The Thermal-Hydraulics modeling tools include the following factors and parameters, which affect wellbore instability and hydraulics.

  • Bottom Hole Pressure (BHP)

  • Thermal expansion of drilling fluid

  • Heating-cooling effect of drilling fluid

  • Equivalent Circulation Density (ECD)

  • Equivalent Static Mud Weight (ESMW)

  • Annular Pressure Build-up (APB) (dynamic)

  • Annular Frictional Pressure (AFP) (dynamic)

  • Choke backpressure (if Managed Pressure Drilling operation) (dynamic)

Wellbore Fluid Analysis

While drilling (under flowing conditions), when Equivalent Circulation Density (ECD) of drilling fluid causes dynamic BHP of the wellbore to be less than pore pressure, results in kicks or when BHP crosses fracture gradient pressure, results in losses. Kicks and losses are the main sources of NPT and associated drilling risks.

During non-flowing conditions (not drilling), movement of the drill string when pulling out of the hole causes the bottom hole pressure to decrease. This is referred to as swab pressure, results in a kick (formation fluid influx). Whereas rise in the bottom hole pressure due to running in the hole is called a surge pressure, results in drilling fluid losses, formation breakdown and wellbore instability.

The Thermal-Hydraulics modeling tools plan and optimise pulling Out of Hole (POOH) and Running-In-Hole (RIH) operation to reduce kicks or losses.

Well Design & Optimization

Well Design and Optimisation Services deliver optimum Casing and Tubing Design (Sections lengths, Casing/liner Sizes) based on safety factors, stress and load analysis derived from Well Performance profiles (hydraulics and thermal profile). Dynamic simulation of well operation provides the well production profile for a variety of operating conditions throughout the well life cycle. These profiles provide the vital insight in well design to ensure efficient production from well over its life span. We offer well Design simulation services for both;

  • Production Well

  • Injection Well (CO2 & Water Injection)

Risk & Integrity Management 

We derive efficient drilling parameters, based on Thermal-Hydraulics modelling tools, within narrow drilling window between pore pressure and fracture gradient pressure for compliance purposes. Our services identify, evaluate all possible risks, (wellbore instability, formation damage due to kicks or losses, differential sticking in conventional wells, casing rupture or equipment failure in HPHT wells) leads to NPT and compromise well integrity and provide a platform to prepare mitigation plan to assure better wellbore integrity with no formation damage and less NPT.

 

Well Plan & Drilling Program 

We use the output from our thermal-hydraulics modelling tools to write well and drilling programs, that include wellbore thermal-hydraulics analysis, well geometries, casing programs, mud considerations, well control concerns, initial bit selections, offset well information, pore pressure estimations, economics, and special procedures, etc. by aiming for characteristics, such as safety, minimum cost and usability.
