iCem® Service

Furthering the pursuit of delivering wellbore integrity, Halliburton invested two years and significant resources in developing the most advanced analytical tool in the industry, iCem® Service.  Based on computational fluid dynamics and finite element analysis, the simulations run with iCem service help enable the evaluation and optimization of cement designs.  iCem service simulations have been tested for accuracy by an independent laboratory in Adelaide, Australia.   

Selecting a cement composition for individual wells that has adequate pumping time, sufficient strength development (without excessive wait-on-cement time), and balanced displacement force is complicated business.  iCem service helps simplify the complexities of achieving a reliable annular seal.  

iCem Service is operated by Halliburton-certified technical professionals globally, iCem service evaluates the effect of changes to variables including mud displacement, slurry properties, casing/pipe movement & centralization, fluid volumes, pump rates, and temperature/pressure differentials in order to optimize the cement placement and sheath design for the life of the well. Prognostic models simulate fluid-flow interaction, displacement phenomena, and stresses in set cement to optimize designs for primary cementing, a reverse-circulation job, a balanced plug job, or a post-cementing job evaluation. It appraises the cumulative effect of stress to the cement sheath from events such as pressure and well testing, injection and stimulation treatments and production cycling. Different results can be compared simultaneously for vigorous design evaluation and in real time during operations, enabling continual improvement from pre-job planning through to post-job analysis.

iCem service is a scientifically-grounded analytical tool to help operators, regardless of the asset they are developing, make better decisions faster.  Simulations that took days to develop and execute are now reduced to 2-3 hours. Such time savings calculated against the global volume of wells planned yearly is the equivalent of the annual man hours for 60 technical professionals, enhancing overall productivity. With a uniform platform and single data entry, iCem service simplifies complexities while enhancing reliability, simulating the cement sheath at any point in the life of the well, helping answer questions before the job is run, enabling the pre-determination of the true top of cement, the fluid intermingling effect on cement purity, and the extent of mud channeling. Such specific investigative modeling helps operators improve well economics with an annular barrier that serves as a foundation for helping increase ultimate recovery.  iCem service enables prediction of required material choices and volumes, potentially reducing the cost of an operation.  iCem service runs various simulations according to specific wellbore architecture design data provided by the operator, enabling cementing solutions to be specifically designed to meet the needs of individual wells in assets worldwide ranging from geothermal to deepwater, unconventional to thermal recovery.

The 3D simulator models multiple aspects of mud displacement and cement placement. Based on computational fluid dynamics, it demonstrates the effect of the key mud-displacement variables that affect successful cement placement during cementing operations:

Mature Fields:

Completion Operations EfficiencyiCem® Service - Predicting Cement Placement

Many mature oilfields represent viable resources. However, mature fields create a variety of challenges in well construction. The primary challenge is the low pressures created by years of production. These low pressure zones create many difficult hole conditions that lead to issues such as lost circulation, unknown fluid levels, long horizontal sections, and poor hole cleaning, just to name a few. All of this has the potential of resulting in poor cementing operations and unacceptable zonal isolation.

Life of the Well:

Achieve Effective Fracture System VolumeiCem® Service for the Life of the Well Cement Sheath Stress Analysis

Wells are subjected to substantial stresses from operationally induced pressure events and temperature cycling. The annular seal can succumb to the cumulative effect of these forces, compromising zonal isolation and reducing the economics of the well by inhibiting production and/or requiring costly remediation.

The University of Adelaide in Australia was selected to assess the dynamic evolution of fluid concentration in the wellbore as a function of time. This flow visualization study assessed the dynamics of fluid-to-fluid displacmeent in eccentric annuli.
Summary Summary iCem Service - Increasing the Probability of Wellbore Integrity
iCem Service enables operators to evaluate critical variables before the cementing operation. iCem Service is the most robust cementing design tool in the industry and it helps to dramatically increase the probability of wellbore integrity.
Summary Summary Casing Rotation
Once casing has been run to depth and the mud circulated and conditioned; the casing is cemented. During cementing; the casing string can be rotated and/or reciprocated to enhance excess wall-cake removal and assist with cement placement to help establish the hydraulic seal. The following video simulates cement placement without casing rotation versus with casing rotation.
Summary Summary Casing Standoff from Annulus (centralization)
Casing is often closer to one side of the borehole; leaving a wide side and a narrow side of the annulus. Fluid velocity differs between narrow and wide annular space and can affect cement placement.
Summary Summary Fluid Rheology
Compatible fluids and spacer rheology are critical to replacing formation-burdened drilling fluid with solids-free fluid to prepare the wellbore to receive cement. Halliburton�s iCem service models fluid properties and relies on a laboratory-proven rheological hierarchy to help determine optimum displacement plan.
Summary Summary Fluid Volume
Spacer fluid is intended to provide sufficient separation of cement slurry from drilling fluid (mud); in order to avoid cement contamination. Thus; spacer fluid volume is important.
