Investigation of hydraulic fracture optimization in on Infill well in low permeability reservoirs

Well infilling has become an effective approach to enhance oil recovery (EOR) for many years. Closely spaced wells and water injections can help maintain reservoir pressure and enlarge producing pressure drop, which are beneficial to the low permeability reservoir development. After more than 20 years of water injection in the Ansai low permeability oil reservoir (Changqing Oil Field, China), water cut of wells now...

A practical approach to the evaluation of subcritical multiphase flow through down-hole safety valves (storm chokes)

A practical approach to the evaluation of subcritical multiphase flow through down-hole safety valves (storm chokes) is presented. This method which is independent of the continuous phase is based on the composition of the flowing mixture and the operating temperature and pressure. In the event of single phase flow, the method can also be applied. With this method, we can easily size subsurface safety valves (SSSV)...

Transfer matrix technique for determining the resonance conditions in retrieving stuck drill pipes with a top vibratory suspended drive

A stuck drill pipe has been recognized as one of the most costly and non-productive challenges in drilling operations. Fishing jars are routinely used to un-lock or loosen the stuck (jammed) pipes which in many cases are expensive and the time taken to complete the job can reach several days of continuous jarring. The use of surface mounted vibratory systems has offered an alternative cost effective means to free the...
