[ 1 ] - Improvement of Cement Properties Using a Single Multi-functional Polymer
Cementing of the casing pipes inside the wellbore is considered as one of the most expensive and difficult operations during the well construction process. A low quality cementing job leads to further repair operations, which are usually costly and time-consuming to conduct. Polymer cements are being used for decades in the oil and gas industry due to their improved properties such as sedimenta...
[ 2 ] - Sedimentation Stability of Oil Well Cements in Directional Wells (TECHNICAL NOTE)
Unsuccessful cementing operation can jeopardize the whole well construction process, resulting in further costly and time consuming repair operations. The quality of cementing job is dependent on the cement composition and its properties. Design of cement composition is based on the available geological condition, materials and technical situation at well location. The cement properties like fl...
[ 3 ] - Considerations of Well Cementing Materials in High-Pressure, High-Temperature Conditions (RESEARCH NOTE)
As worldwide demand of hydrocarbon is growing fast, the oil and gas companies have been forced to explore reservoirs with more hostile conditions, such as high-pressure, high-temperature conditions. Improved technology, material selection and testing procedures are required to overcome the common problems in these conditions. One of the main phases of well construction is cementing job. Appropr...
[ 4 ] - Optimization of Cement Spacer Rheology Model Using Genetic Algorithm (RESEARCH NOTE)
The primary cement job is a critical step in successful well completion. To achieve effective cementing job, complete mud removal from the annular is recommended. Spacer and flushers are used widely to achieve this goal. This study is about weighted cement spacer systems containing a surfactant package, weighting agent and rheological modifiers. Weighted spacer systems are utilized when a high ...
