... Abstract Majority of gas fields in Tarim Basin are HPHT (high-pressure/high temperature) reservoirs with buried depth more than 5000m. The special geological conditions made it a challenge for underground well testing due to safety issues. Additionally, wellhead pressure fluctuation is widely...

... of yield stress, the volume of suspended single bubbles increases, the gas suspension concentration increases, and the height at which the gas can rise is reduced. When the yield stress of drilling fluid is 2 Pa, the increment of wellhead pressure decreases by 37.1% compared with that without considering...

... approximately 3,000 BOPD under flowing wellhead pressure of 800 to 900 psig, with oil gain of over 3-fold compared with previous oil rate; water cut reduction from 30% to zero; better blended oil quality handled to medium crude; and saving artificial-lift cost. This process may be widely applied in the similar...

Additionally, the operator previously had negative experiences on the same well with other CT companies who tried to perform a PBU test with fiber optics, resulting in three missed runs and production loss.

... for wells with high flowing wellhead pressure such as deep gas wells and wells with rig-up space restrictions such as small offshore platforms and/or jackets. However, one of the main drawbacks for M_PL is that its data can't be quality controlled in real-time, which is important if real-time decisions need...

... caused by opening the well (without switching on the ESP). Operations observed high pressure on wellhead and decided to open up the well to let it naturally flow from time to time when the wellhead pressure built-up and then shut in again when the pressure dropped. This will be discussed in more detail...

...), Permeability Thickness (kh), Tubing Size, and Flowing Wellhead Pressure. The model shows that for high kh (Permeability Thickness) completions, tubing size has only a minor effect on the reservoir abandonment pressure. Actual field data confirms the model's predicted results. Refer to the result of the study...
