Tubing/Packer System

a suitably selected packer by using also operations efficient. Wireline pressure and logging operations go faster and smoother. Longer fliess life will be achieved with the use of a packer through the optimal use of gas energy. Technical Data about in this  field explained in petroleum courses in Rawalpindi.

Carry out the use of a packer in a gas well with a tail pipe with the perforations, will alleviate the problem of gas sources headline, with water loading and die prematurely. (The water is continuously generated as a mist and is not allowed to build up over the perforations.) This use of a packer and tailpipe will not control the natural water flow, but will keep the water along to disposal at the time transportable pressure is less than the pressure required to flow. Some more details of petroleum courses in rawalpindi are as under.

Where Packers are not used:

Packers are not in rod-pumped wells, unless exceptional circumstances such as Dual final call for a run. Electric submersible pumped wells would have no Packer, except when used with uphold subsurface safety valves by government safety regulations for offshore wells required. Many naturally flowing, high-volume, Sweet Crude Wells are the ring without Packer produces up; to be good and to kill (circulate) or for the execution of specific protocols or gauge a small tubing runs. Dry, sweet gas wells often produce up both the tubes and the ring and have no packer.

Well Operational modes:

There are four operating modes, which each could well occur where: (1) shut-in; (2) Preparation of (either liquid, gas or a combination); (3) injection (hot or cold liquids or gases); or (4) treating (high, low or medium pressures and volumes).

The usual mode of operation is only one of the factors that must be considered when a particular type of packer selection are well used in a. Subsequent operations and its pressure and temperature changes are likely to be extremely important to be successful utilization Packer. Typical 2,3-temperature vs. depth profiles are shown in FIG. 4.9. These profiles are similar to those measured in wells in one of four modes: shut-in, production, injection or treatment. Coward. 4.9a shows a typical geothermal gradient, with the temperature with the depth of the bottom hole temperature increases (BHT). Every time a well closed in, the operating temperature profile will begin towards the shape of the natural geothermal profile move. The production and temperature profiles for gas and oil, are shown in Figs. 4.9b. The wellhead temperature of an oil well is a little less than BHT. The amount of as a crude cooling flows at the surface depends on several factors: (1) the relative amount of oil and water, (2) the specific heat of the oil and water, (3) the flow velocity, (4) the gas / liquid ratio, and (5) of the vertical flow pressure drop, the gas freed controls and related cooling effect. The temperature profile of a gas well may have a wellhead temperature lower than the ambient temperature. In any case, the temperature of a gas well wellhead on the BHT will depend on the flow velocity, the pressure drop in the pipeline, the specific heat of the gas, and other factors.
