ANALYSIS OF DRILLING FLUID COMPOSITION
- Analysis of drilling fluid composition for compliance to actual subsurface conditions during drilling. Development of recommendations for optimization of composition, if required. There are no "all purpose“ drilling fluids.
- Drilling fluid compositions are selected in order to achieve the properties which provide the most effective drilling in the given subsurface conditions and to maintain such properties during drilling.
- Drilling fluid which has been correctly selected and prepared ensures not less than 50% of successful drilling without complications and accidents.
- IES specialists perform selection and optimization of compositions to suit the given subsurface conditions taking into consideration characteristics of the region where the works are performed.
- IES specialists perform selection and optimization of compositions to suit the given subsurface conditions taking into consideration characteristics of the region where the works are performed. We practise an individual approach to the selection of drilling fluids. This allows to ensure efficiency of drilling and optimization of expenses.
CONTROL OVER LABORATORY TESTS
Laboratory tests are an important element in the well construction process. American Petroleum Institute (API) has developed standards for field and laboratory testing of drilling fluids: API Recommended Practice for Field Testing Water-Based and Oil-Based Drilling Fluids (API RP 13B-1, 13B-2 for field testing and API RP 13I for laboratory testing of drilling fluids).
Conducted laboratory tests are aimed at accomplishment of the following specific objectives:
- Testing and selection of drilling fluid compositions to be applied in specific subsurface conditions.
- Study of rheological, filtration, inhibitive and lubricating properties of drilling fluids, clay colloidity.
- Control over quality of chemical agents and lubricating additives.
- Study of granulometric and compositional content of solid phase of dispersed systems.
Our specialists are equipped with equipment from the leading foreign companies which enables to perform testing in full, on high technical level and in accordance with international standards. Set of testing equipment includes apparatus for determination of standard drilling fluid properties: density, funnel viscosity, fluid loss, stability, sand content, rheological properties etc.
Our specialists also check laboratory equipment for compliance with API standards, period of validity of chemical reagents for testing, calibration of laboratory equipment. Failure to comply with the standards causes incorrect values, which in their turn may lead to making wrong decisions.
DRILLING FLUID QUALITY CONTROL
- Drilling fluid quality control is aimed at obtaining true information about the current values of its parameters in order to timely identify their deviations from the designed values and take effective measures to adjust the properties and avoid complications.
- Mixing water quality control.
- Control over contamination of drilling fluid.
- Control over solids phase content.
- Significant part of complications during drilling is caused by non-conformity of drilling fluid properties with subsurface conditions. Elimination of complications requires more money and time than taking preventive measures.
ENGINEERING CALCULATIONS
- Determination of hydraulic losses in annulus and equivalent circulating density of drilling fluid.
- Calculation of required volumes of drilling fluid.
- Calculation of consumption of chemical agents for mixing or treatment of drilling fluid.
CONTROL OVER QUALITY AND CONSUMPTION OF CHEMICAL AGENTS
- Carrying out audit of storage place of chemical agents.
- Checking storage conditions and validity term of chemical agents.
- Checking certificates of quality of chemical agents for compliance with ISO 13500.
- Provision of recommendations for substitution of chemical agents for their analogues (if needed).
- Control over consumption of chemical agents.
AUDIT OF CIRCULATION SYSTEM AND SOLIDS CONTROL SYSTEM
Audit represents a structured process of collection of independent information about efficiency, reliability and productivity of all elements of circulation system and solids control system, as well as development of measures to remedy identified flaws.
Audit of circulation system covers: tanks, mixing hoppers, mud reserve tanks, sand traps, trip tanks etc., as well as correct layout and quantity of equipment. The following is checked: type, model, technical specifications, availability of the basic consumable materials for all the elements mentioned above
Audit of solids control system covers: shale shakers, desilters, desanders, centrifuges, degassers etc., as well as correct layout and quantity of equipment. The following is checked: type, model, technical specifications, availability of the basic consumable materials for all the elements mentioned above.
