cementing operations
Course Description
The course covers aspects of primary, squeeze and plug cementing, and primary cementing calculations. Cement chemistry is introduced to understand the process involved in achieving a satisfactory cement job. Additives used to affect various properties of the slurry and set cement are addressed. Rheological models used during cement job design and requirements for effective mud removal will be covered. Cementing aids and job quality evaluation methods are dicussed.
Classroom exercises as well as an introduction to cementing design and evaluation software are included.
Audience
Drilling professionals with some understanding of the drilling process.
Prerequisites
Basic knowledge of the oil & gas industry. Some understanding of cement use is strongly recommended. Participants will need to provide a hand calculator and be prepared to perform exercises in class.
Course Schedule
| 1 | Primary Cementing Overview & Calculation - Review purpose of primary cementing, primary cementing calculation, types of casing, typical cementing procedures from conductor, outside cementing, thru-tubing, and two-stage cementing to liner cementing, mixing equipment and casing hardware. Cement Chemistry - Fundamental information regarding the manufacture, hydration and classification of Portland cements. Evaluation of the effects of various chemical and physical parameters on performance. |
| 2 | Cement Laboratory Equpiment - Performance evaluation of slurries and equipment used to evaluate thickening time, rheology, fluid-loss, free water, compressive strength, and slurry stability. Rheology - Review of rheological models used in cementing – Newtonian, Bingham Plastic, Power Law and Herschel Bulkley. Cement Additives - Mechanism of action and use of different categories of cementing additives – accelerators, retarders, extenders, weighting agents, dispersants, fluid-loss additives, lost circulation control agents, and speciality additives - to improve and reduce job costs. |
| 3 | Mud Removal - Effective mud removal criteria. Displacement selection in laminar and turbulent flow; application of washes and weighted spacers. Importance of stand-off. Gas Migration Control - Consequences of gas migration, gas migration paths, root causes for gas migration, gas-migration-control slurries. Cementing Temperature - Overview of API Schedules, heat transfer in a well, software temperature module, temperature in deep-water conditions, static temperature determination, misuse of temperature from MWD/LWD tools, TOC temperature evaluation. |
| 4 | Squeeze Cementing - Applications (when to use), squeeze techniques - high and low pressure, running and hesitation techniques, squeeze tools, slurry design and volume estimation, injection test, downhole tools, conventional and coiled tubing placement. Cementing Plugs - Applications, plug placement, plug location, slurry volumes, plug balancing, avoiding contamination. |
| 5 | Introduction and review of cementing design and evaluation software Special purpose cements Course review |
