Abstract: Cementing is one of the most important and fundamental phases of any oil and gas wells drilling operations. In addition, by increasing the oil and gas production, the reservoir becomes depleted. Thus, for production rate enhancement, new wells are drilled. Cementing jobs at low pressure or fractured layers must be conducted by light or ultra-lightweight slurries.  Therefore, the formation damage that is caused by slurries, reduces essentially. One of the latest technologies for ultra-lightweight cementing jobs is the foamed cement formulation. In this thesis, the new foamed cement formulation and designing for Iranian liner and casing cement jobs are investigated. Foamed cements are prepared at high shear rates by sodium lauryl ether sulphate (SLES) as a foaming agent. The optimum concentration for SLES and optimum mixing procedure are evaluated and other additives for a particular property are added to the slurry. 

Different tests such as foam stability, density measurement, rheology, free water, thickening time, compressive strength, fluid loss, porosity, permeability, microscopic photography and CT scan image processing are conducted for each of cement samples. The results of these experiments for FBJ (best-formulated foamed cement in this study) are compared to other common lightweight cements that are used in Iranian fields, for instance, the south Azadegan oil field. The FBJ foamed slurry consists different components, for best-foamed cement properties and formulation, that are 778gr net class G cement, 350gr distilled water, 0.78gr (0.1% BWOC) SLES as a foaming agent, 0.78gr (0.1% BWOC) JR120 as a retarder and 0.78gr (0.1% BWOC) boric acid. The results illustrate that the FBJ has one of the lowest densities in the Iranian cementing industry with enough compressive strength. The density of FBJ is 75pcf with more than 1300psi compressive strength. Its thickening time is near 3 hours and its rheology becomes better in wellbore condition and this is a result of bubbles ball-bearing effect. Due to the foamy structure of FBJ, this slurry has no free water and fluid loss. The porous media of FBJ’s set-cement are not interconnected and this is proved by porosity, permeability, microscopic photography and CT scan tests. Also, CT scan analyses show that FBJ’s foamy structure is saved in the set-cement in high pressure- high temperature (HPHT) condition.

B.Sc. in Petroleum Engineering (Area of Interest: Reservoir Engineering)

Thesis: “Laboratory Design of an Apparatus for Evaluation of Formation Damage Caused by Various Drilling Muds” 

Advisor: Dr. Masoud Riazi

Abstract: Drilling fluid selection seems to be a usual and ordinary section of a drilling job. However, this part of an operation is very critical and precise. The selected drilling mud must have several features to optimize a drilling operation such as:

  • Transferring appropriate hydraulic pressure to the wellbore (controlling formation pressure);

  • Minimizing formation damage;
  • Cool, lubricate, and support the bit and drilling assembly;
  • Remove cuttings from well and suspend and release cuttings;
  • Facilitate cementing and completion;
  • Minimize impact on the environment, etc.

All of these properties are obtained by formation features. Thus, different experimental tests are conducted on drilling fluids to reach the mud with adequate traits. One of the properties which are hard to estimate is how much the drilling fluid cause formation damage?

Therefore, in this research, an apparatus has been designed to evaluate formation damage. This instrument has two parallel cylinders that had been filled with the sand pack by particular porosity and permeability. The interior cylinder is a model of a well and the external one is a model of the reservoir. The drilling mud is pumped to the modeled well and permeability changing is calculated. Hence, formation damage can be evaluated by this plan. Also, this apparatus can be used for injection process modeling in production and EOR operations for different fluids.

Moreover, various drilling fluids, their additives and their effects on the formation damage are introduced in this project.

Furthermore, in the last chapter (Appendix), for better investigation of modeling of drilling fluid flow in the reservoir porous media and its interactions with reservoir rock/fluids have been described. In addition, drilling mud effects on the fine migration phenomenon are presented in this section.
