Sentence examples for wellbore system from inspiring English sources

We determined that considering the initial loaded state can cause substantial differences in the estimated stress distribution of the entire wellbore system.

This concept is underpinned by the assumption of consistency in the behaviour of the wellbore system matched by different operating conditions.

According to the multi-phase flow theory, the density of the drilling fluid mixture and the bulk elastic modulus of the wellbore system can be expressed as Eq. 4 5.

The model is derived according to the elastic mechanics theory, which can consider the loading history of the entire wellbore system and take account of its initial loaded state.

The wellbore system becomes unstable when the integrity of the wellbore and surrounding formation can no longer hold or is threatened due to induced stresses or the weakening of the wellbore or formation materials.

Designing and maintaining the long-term integrity of an entire wellbore system is important to all its operations and to prolonging the service life of the oil and gas well.

Wellbore systems are designed to isolate fluids in the subsurface and are typically engineered for a 30 50 year service life.

Case studies including oil water and oil gas flow in horizontal wellbore systems are conducted, together with detailed interpretation of fluids thermal behaviors.

A set of base-case mudcake parameters as well as other parameters of the mudcake-wellbore system are reported in Table 1.

For highly deviated wells, in situ stress interpretation based on stress indicators is carried out by transforming the regional stress field into the wellbore coordinate system.

This paper describes how the thermal behavior of a tubular-wellbore-reservoir system is altered during mud loss, as well as its consequent impact on near-wellbore state of stresses and critical mud weights.
