Cutting of damaged pipes, of windows; Deforming of pipes in boreholes or wells; Reconditioning of well casings while in the ground by explosives or by thermal or chemical means Abstract. A method of removing a downhole tool from a wellbore comprising contacting the tool with a heat source wherein the tool comprises at least one load-bearing component comprising a thermally degradable material.

A method of reducing the structural integrity of a downhole tool comprising fabricating the load-bearing components of the tool from a thermally degradable material. A method of removing a downhole tool comprising mechanically milling and/or drilling the tool from a wellbore wherein the tool comprises at least one load bearing component comprising a phenolic resin wherein the phenolic resin comprises a rosole, a novalac or combinations thereof.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT Not applicable.

REFERENCE TO A MICROFICHE APPENDIX Not applicable. FIELD OF THE INVENTION The present invention relates to consumable downhole tools and methods of removing such tools from well bores. More particularly, the present invention relates to downhole tools comprising materials that are burned and/or consumed when exposed to heat and/or an oxygen source and methods and systems for consuming such downhole tools in situ.

BACKGROUND A wide variety of downhole tools may be used within a well bore in connection with producing hydrocarbons or reworking a well that extends into a hydrocarbon formation. Downhole tools such as frac plugs, bridge plugs, and packers, for example, may be used to seal a component against casing along the well bore wall or to isolate one pressure zone of the formation from another. Such downhole tools are well known in the art.

After the production or reworking operation is complete, these downhole tools must be removed from the well bore.

The Uganda Sports Day Festival UK will look to five objectives; To promote a healthy lifestyle among Ugandans living/working in the United Kingdom. Celebrating the Sports Day will highlight the role that sport plays as a factor in creating healthy communities/institutions at both physical and psychological levels To acknowledge the past and recognize current sports achievers.

There are a number of Ugandan sportsmen/women, administrators who have represented this country with honor at the international level in the United Kingdom, but who have long been forgotten or should be honored for their contributions to sport. These will be honored on this day To offer a platform that will strengthen relationships among the Ugandans living in the United Kingdom. To educate/update the Ugandan community in the United Kingdom of the available business opportunities and potential partners in Uganda. And finally to raise support (financial and logistical) for the unprivileged youngsters striving to build their careers through sport. Background to the Uganda Sports Day UK Festival For years, Ugandans based in the United Kingdom have not shared a platform that would unite them, reinvigorate their enthusiasm for sports or remind them of the responsibility to live a healthy life. It must be noted that the population of Ugandans living in the United Kingdom is quite substantial.

The 2001 UK Census recorded a total of 55,213 people born in Uganda resident in the UK. The 2011 UK Census recorded 59,227 Ugandan-born residents in England.

The Office for National Statistics estimates that in 2014, 51,000 people born in Uganda were resident in the UK. A mapping exercise undertaken by the International Organization for Migration in 2006 reported that community representatives estimated that there were between 300,000 and 750,000 Ugandans in the UK, including Ugandan Asians. And a majority of these Ugandans live in and around London. Clearly these are statistics that should not be ignored and the Uganda Sports Day UK will be the easiest platform to bring this Ugandan community together using the power of sports.
