Description: A wireline insert, Surface Contror permission to publish this paper. A special thanks to BJ tools specialiolled Sub-Surface Safety Valve (SCSSV), has been successfully installed for an operator in the Gulf of Mexico, in a well, which had lost control line integrity. The new Control line was installed "thru-tubing", using capillary tubing and wireline disciplines.

Application: The Minerals Management Service (MMS) reluctantly grants variances to oil and gas operators who request permits to install storm chokes, on wells which have lost control line integrity. Storm chokes do not allow for surface control and are less safe than the mandated SCSSV's. The new system has been MMS approved and offers operators a safer alternative, which is less costly than a workover and more flexible than a strom choke or velocity valve.

Results, Observations, Conclusions: The new system was installed and the well is flowing trouble free whilst having complete surface control capability. Subsequently, the operator has had the flexibility to substantially increase the production rate avoiding the necessity of adjusting differential pressure settings as with a velocity type valve.

This system has an enormous impact on the environment and economics. The most reliable method of controlling a subsurface safety valve is with a direct hydraulic system. Preserving use of a direct control system has historically been a focus of operators and encouraged by governing bodies. Reconnecting direct control of the safety valve relieves operators and governing officials from having to make difficult decisions regarding a safety issue. Aside from the apparent safety advantage, the system presents economical advantages as well. Operators maintain the option for flowing at maximum rates and are relieved of frequent maintanence expenses associated with velocity type devices. Case in point, the operator has had the ability to adjust production rates from 1 mmcfd to 5.2 mmcfd.

Significance of Subject Matter: This system has an enormous impact on economics and the environment. Considering the single pod well, the operator now has the option to negate the bi-annual inspection of a storm choke or velocity valve, which would require a lift boat operation each time. Additionally, this API 14A product will prevent the necessity of a workover, avoiding costs which may render the remaining reserves, uneconomic.
