Completion tools

Completion, in petroleum production, is the process of making a well design for production (or injection). This principally involves preparing the bottom of the hole to the required specifications, running in the production tubing and its associated down hole tools as well as perforating and stimulating as required. Sometimes, the process of running in and cementing the casing is also included.

Barefoot completion

This type is the most basic, but can be a good choice for hard rock, multi-laterals and underbalance drilling. It involves leaving the productive reservoir section without any tubulars. This effectively removes control of flow of fluids from the formation; it is not suitable for weaker formations which might require sand control, nor for formations requiring selective isolation of oil, gas and water intervals. However, advances in interventions such as coiled tubing and tractors means that barefoot wells can be successfully produced.

Open Hole

The production casing is set above the zone of interest before drilling the zone. The zone is open to the well bore. In this case little expense is generated with perforations log interpretation is not critical. The well can be deepened easily and it is easily converted to screen and liner. However, excessive gas and water production is difficult to control, and may require frequent clean outs. Also the interval can not be selectively stimulated.

Open hole completion

This designation refers to a range of completions where no casing or liner is cemented in place across the production zone. In competent formations, the zone might be left entirely bare, but some sort of sand-control and/or flow-control means are usually incorporated.

Openhole completions have seen significant uptake in recent years, and there are many configurations, often developed to address specific reservoir challenges. There have been many recent developments that have boosted the success of openhole completions, and they also tend to be popular in horizontal wells, where cemented installations are more expensive and technically more difficult. The common options for openhole completions are:

Well Construction Projects

The reason of each oil and gas well, in spite of complexity, is the cost-effective revival of hydrocarbons. Well-organized and economical Well Construction is a fundamental piece of this attempt. supervision Well Construction Projects require a methodical understanding of all facet of the good procedure, from geology to production, with the aptitude to put together industry best practices and cutting border oilfield technologies. neoz Project Management team start with a wide pre-planning process to completely understand the risk and objective of each project. The input to this approach is to work together with all stakeholders to totally understand each condition and then expand a solid design and an effectual program for your high-quality construction project.
